The House Heating Curve
The heating curve is the central part of the product’s control system. It is the heating
curve which determines the compensated flow temperature requirements for your
property dependent upon the outdoor temperatures. It is important that the heating
curve is correctly adjusted, so that you achieve the best operation and economy
possible.
One property requires a radiator temperature of 30 °C when the outdoor temperature
is 0 °C, whilst a different property requires 40 °C. The difference between different
properties is determined by the radiator surface area, the number of radiators and how
well insulated the house is.
!
The set heating curve is always given priority. The room sensor can only increase
or decrease the compensated flow temperature to a certain extent above the set
heating curve. Where operating without a room sensor, the selected heating curve
determines the flow temperature supplied to the radiators purely from the outside
temperature reading.
Adjustment of Default Values for the Heating Curve
You define the heating curve yourself for your property by setting two values in
the product control system. This is achieved by selecting the options Inclination or
Adjustment under the Installer/Settings/Radiator system menu. Ask your installer to
help you set these values.
It is extremely important to set the heating curve and, in some cases, unfortunately,
this process may take several weeks. The best way of doing this, upon the initial
start-up, is to select operation without any room sensor. The system then operates
using the outdoor temperature reading and the property’s heating curve only.
During the adjustment period it is important that:
• the night reduction function is not selected.
• all thermostat valves on the radiators be fully opened.
• the outdoor temperature is not higher than +5 °C. (If the outdoor temperature is
higher when the system is installed, use the factory set curve until the outdoor
temperature falls to a suitable level.)
• the radiator system is operational and correctly adjusted between different
circuits.
Appropriate Default Values
During installation you can seldom achieve a precise setting for the heating
curve instantly. In this case, the values given below may provide a good starting
point. Radiators with small heat-emission surfaces require a higher primary flow
temperature. You can adjust the gradient (heating curve gradient) for your heating
system under the Installer/Settings/Radiator system menu.
Recommended values are:
8
Floor heating only
Inclination 35
Low temperature system (well insulated houses)
Inclination 40
Normal temperature system (factory setting)
Inclination 50
High temperature system
(older houses, small radiators, poorly insulated)
Inclination 60
CTC EcoZenith i250
General Information
Adjusting the heating curve
The method described below can be used to adjust the heating curve correctly.
Adjustment if it is too cold indoors
• If the outdoor temperature is lower than 0 degrees:
Increase the Inclination value by a couple of degrees.
Wait 24 hours to see if any further adjustment is required.
• If the outdoor temperature is higher than 0 degrees:
Increase the Adjustment value by a couple of degrees.
Wait 24 hours to see if any further adjustment is required.
Adjustment if it is too warm indoors
• If the outdoor temperature is lower than 0 degrees:
Decrease the Inclination value by a couple of degrees.
Wait 24 hours to see if any further adjustment is required.
• If the outdoor temperature is higher than 0 degrees:
Decrease the Adjustment value by a couple of degrees.
Wait 24 hours to see if any further adjustment is required.
!
If the values set are too low, this may mean that the desired room temperature
is not being reached. You then need to adjust the heating curve, as necessary,
following the method shown above.
When the basic values have been set more or less correctly, the curve can be
finely adjusted directly using the Room temp. shown on the home menu screen.
Description of inclination and adjustment
Inclination 50:
The value set is the outgoing temperature of the water supplied to the radiators at an
outdoor temperature of –15 °C, e.g. 50 °C. A lower value is selected where a radiator
system has large radiator areas (a low temperature system). Floor heating systems
require low temperatures. A low value should therefore be selected. The value must be
increased for high temperature systems to achieve a high enough indoor temperature.
Adjustment 0:
The adjustment means that the flow temperature can be raised or lowered at a specific
outdoor temperature.
Adjustment 0 means 50 °C primary flow when the outside temperature is -15 °C.
Adjustment -5 means 45 °C primary flow when the outside temperature is -15 °C.
For example:
Inclination 50 means that the temperature of the water supplied to the radiators will
be 50 °C when the outdoor temperature is –15 °C (if adjustment is set to 0). If the
adjustment is set to +5, the temperature will be 55 °C instead. The curve is increased
by 5 °C at all temperatures, i.e. it is parallel displaced by 5 °C.

General Information
Examples of Heating Curves
You can see in the diagram below how the heating curve
changes with different Inclination settings. The gradient of
the curve shows the temperatures that the radiators require
at different outdoor temperatures.
Primary Flow Temperature
Curve Inclination
The inclination value which is set is the primary flow
temperature when the outside temperature is –15 °C.
Outside Temperature
Heating off, out
Adjustment
The curve can be parallel displaced (adjusted) by the
desired number of degrees to adapt to different systems/
houses.
Inclination 50 °C
Adjustment +5 °C
Primary Flow Temperature
Inclination 50 °C
Adjustment 0 °C
Outside Temperature
Heating off, out
An example
Inclination 60 °C
Adjustment 0 °C
Primary Flow Temperature
In this example, the maximum outgoing primary flow
temperature is set at 55 °C.
The minimum permitted primary flow temperature is 27 °C
(e.g. summer-time basement heating or the floor circuits in
a bathroom).
Outside Temperature
Summer-time operation
All properties have internal heat gains (lamps, oven,
personal heat etc.), which means that the heating can be
switched off when the outdoor temperature is lower than
the desired room temperature. The better insulated the
house is, the earlier the heating from the heat pump can be
switched off.
The example shows the product set at the default value of
18 °C. This Heating off value can be changed under the
Installer/Settings/Radiator system menu.
When the heat is switched off in this way, the radiator
pump stops and the mixing valve is shut down. The heating
starts up automatically when it is required again.

General Information
4. CTC EcoZenith i250 design
The picture below shows the basic construction of CTC EcoZenith i250.
If a heat pump is connected, the energy in the air or bedrock/ground is drawn
up by the cooling system. The compressor then increases the temperature
to a usable level. Afterwards it releases the energy for the heating system
and hot water. The built-in immersion heaters help when additional heat is
needed or when a heat pump is not connected.
Fresh Water Connections
Here you connect the
property’s fresh water
connections. The cold water
is fed down and heated in
the lower part of the coiling.
Bivalent Mixing Valve
The automated mixing valve
ensures that an even heat is
continuously supplied to the
radiator system.
Upper part
In the upper part of the coil
the hot water is then heated
to the desired temperature.
Insulation
The heat pump’s tank is
insulated with die-cast
polyurethane foam for minimal
heat loss.
Finned Coil for Hot Water
The EcoZenith i250 is
equipped with a welldimensioned finned coil made
of copper. Since hot water is
not stored, there is no risk of
legionella bacteria.
Upper immersion heater
Built-in upper immersion
heater. When connected to
a heat pump, the immersion
heater acts as additional heat.
Lower immersion heater
Built-in lower immersion
heater. Not used in normal
operation when the heat
pump is connected.
Draining/expansion vessel
connection
Two connections in the
lower part of the product
where water from the boiler
and radiator system can be
drained and an expansion
vessel connected.
14
Heat pump pipes
The CTC EcoZenith i250 L
is equipped with connection
pipes for top connection
CTC EcoZenith i250
Lower part
In the lower part of the coil
the hot water is pre-heated by
the water heated by the heat
pump. The major section of
the coil is located in this part.
Expansion connection
15 mm.
Diverting valve
The heated water from the
heat pump heats up the
upper or lower part of the
tank alternately.
Heat medium pump
The adjustable-speed charge
pump transports the cold
water from the boiler to the
heat pump where the energy
from the air or bedrock/ground
is drawn up and taken back to
the boiler.
The boiler is supplied with a
circulation pump for a heat
pump of up to 12 kW!

ensures that you are provided with optimum function
and economy. These values are easy to change as and
when required. Ask your installer to help you determine
the correct values.
Heat pump
On delivery the CTC EcoZenith i250 is ready for
connection to a CTC heat pump – either the CTC EcoAir
400 outdoor air heat pump, the CTC EcoAir 520M or
the CTC EcoPart 400 bedrock/ground source heat
pump.
NB: Note that the connection of the CTC EcoAir 520M
inverter is dealt with in a separate section!
This means that the control system already contains all
the controls for the heat pump. When the heat pump
has been defined (On) the CTC EcoZenith i250 senses
which heat pump has been connected
Installer/Define/Heat pump
Once this has taken place the menus for the heat pump
are displayed. On delivery the compressor is blocked
and must be set to permitted. This is done under the
Installer/Settings/Heat pump menu.
Menu structure
The product’s menus are described on the following

Faults
!
If a fault occurs with an outdoor sensor, the product
triggers an alarm and an outdoor temperature of -5 °C is
simulated so that the house does not get cold.
The thermostats of the radiators
must be fully open and well
operating when the system is
tuned.
If a fault occurs with a room sensor, the product triggers
an alarm and automatically switches to operating
according to the set curve.

For example:
“Inclination 50” means that the temperature of the water
supplied to the radiators will be 50°C when the outdoor
temperature is -15°C, if the adjustment is set to 0. If the
adjustment is set to +5, the temperature will be 55°C

General Information
Inclination (default setting)
50(25...85)
Inclination means the temperature your property needs
at different outdoor temperatures. See more detailed
information about this in the chapter on Your property’s
heating installation. The value set corresponds to
the temperature of the radiators when the outdoor
temperature is -15ºC. After this default setting, fine
adjustment takes place in the “Room temperature”
menu.
Adjustment
0 (-20...20)
The curve adjustment means that the temperature
level can generally be raised or lowered at all outdoor
temperatures. After this default setting, fine adjustment
takes place in the “Room temperature” menu.
Room temp. reduced
-2 (0...-40)
“Room temp. reduced” is displayed if a room sensor is
installed.
You define here how many degrees the room
temperature will be reduced by during the various
scheduled reduction periods, e.g. Night reduction,
Holiday, etc.
Example:
Room temp red -2 means that the room temperature is
reduced by 2 °C from its normal temperature.
Example:
As a general rule, a Prim reduced value of 3-4 °C is
equivalent to a 1 °C reduction in room temperature in a
normal system.
Prim reduced
-3 (0...-40)
If there is no room sensor installed, “Prim reduced” is
displayed instead.

General Information
8.7.3 Electric heater
Upper boiler °C
50 (30...60)
Temperature when the immersion heater kicks in
and helps EcoZenith i250 to produce domestic hot
water when there is great demand. A low setting is
recommended.
The immersion heater is also responsible for providing
the house with additional heating. If the house requires
a higher temperature than that selected, the control
system compensates by automatically raising the
temperature of the immersion heaters.
This temperature also reflects the settings chosen under
DHW.
Upper boiler add heat °C
57 (30...70)
The temperature of the boiler when EcoZenith i250
calls for assistance to reach the high temperature; the
immersion heater then works up to this value after the
set time delay on the mixing valve.
Upper boiler extra DHW
60 (30...70)
This means the boiler is to provide extra DHW. This
setting determines whether the electric heater should
help to produce extra hot water. Set the temperature
of the electric unit to the desired value when the option
for extra hot water is activated under the DHW menu.
A lower value means that the heat pump produces the
majority of hot water, not the immersion heater.
Upper boiler max. kW
5.5 (0...9.0)
You set the max. permitted power for the immersion
heater here.
Setting for the maximum permitted power for the electric
unit. 0 to 9.0 kW in steps of 0.3 kW.

Specify here whether operating thermostat function is

want to charge your EcoZenith from a water-jacketed
stove, or another heating source.
However, this function cannot be combined with the
same function in a solar heating system (when e.g. an
EcoTank is connected to an EZ 250). This is because
the same outlets and sensors are used for both
functions.
Information about the Differential thermostat function will

General Information
9. Operation and
Maintenance
When the installer has installed your new system, you should check along
with the installer that it is in perfect operating condition. Let the installer show
you where the switches, controls and fuses are so that you know how the
system works and how it should be maintained. Bleed the radiators after
around three days of operation and top up with water if required.
increase
decrease
Boiler and radiator system safety valve
Check around four times a year that the valve is working by manually turning
the control. Check that water is coming out of the safety valve discharge.
Mixing Valve
The mixing valve is operated automatically from the control system, ensuring
that the radiators reach the correct temperature, no matter what season it
is. However, where a fault occurs, you can operate the valve by pulling out
the knob on the motor and turning it clockwise to reduce the temperature or
anticlockwise to increase it.
Draining the tank
The CTC EcoZenith should be disconnected from the power source when
it is being drained. The drain valve is positioned at the bottom left of the
unit when viewed from the front, behind the front of EcoZenith. When
draining the whole system, the mixing valve should be fully open, i.e. turned
anticlockwise as far as it will go. Air must be supplied to the closed system.
!
Do not forget to reset the mixing valve
to the automatic
position by pushing
in the knob again.
Operation stop
The CTC EcoZenith i250 is shut down using the operating switch. If there
is a risk of the water freezing, all the water should be drained from the heat
pump and the radiator system (see drainage above).
The DHW circuit, which contains around five litres, must also be emptied.
Disconnect the cold water connection to CTC EcoZenith i250. Feed a hose
into the cold water connection to CTC EcoZenith i250. The hose must go
down to the bottom of the coil for all the water to be drained. Draining is
carried out by siphoning out the water.

General Information
10. Troubleshooting/appropriate measures
The CTC EcoZenith i250 is designed to provide reliable operation and high
levels of comfort, and to have a long service life. Various tips are given
below which may be helpful and guide you in the event of an operational
malfunction.
If a fault occurs, you should always contact the installer who installed your
unit. If the installer believes the malfunction is due to a materials or design
fault, then they will contact Enertech AB to check and rectify the issue.
Always provide the product’s serial number.
DHW
Many people want to gain maximum benefit from the CTC EcoZenith i250’s
low operating costs.
!
The control system is equipped with three comfort levels for hot water. We
recommend starting at the lowest level and if there is not enough hot water,
increase it to the next level. We also recommend that you operate a regular
hot water pattern.
Check that the hot water temperature is not being affected by a poor mixing
valve, whether in the CTC EcoZenith i250 or possibly the shower mixer.
The Heating System
A room sensor, which should be fitted when possible, ensures that the
temperature in the room is always suitable and stable. For optimal running,
radiator thermostats should always be fully open in the area where the room
sensor is located.
!
Avoid running hot
water at the highest
flow capacity. If you
run a bath at a rather
slower rate instead,
you will get a higher
temperature.
Avoid placing the
room sensor close
to the stairway due
to the uneven air
circulation.
A correctly operating heating circuit is of significant importance to the heat
pump’s operation and affects energy savings.
When adjusting the system, always do so with all radiator thermostats fully
open. The thermostats can be individually adjusted after a few days in rooms
where lower temperatures are desired.
50
CTC EcoZenith i250
!
If you do not have
radiator thermostats
on the upper floor,
you may need to
install them.
General Information
If you do not achieve the set room temperature, check:
• that the radiator system is correctly adjusted and is functioning
normally. that radiator thermostats are open and the radiators are
equally warm all over. Touch the entire radiator surface. Bleed the
radiators. The CTC EcoZenith i250's economical operation demands a
radiator system that functions effectively.
• that EcoZenith is operating and no error messages are displayed.
• that there is sufficient electrical power available. Increase if necessary.
Also check that the electric power output is not limited due to
excessively high electricity loads in the property (load monitor).
• that the product is not set to the “Max. allowed primary flow
temperature” mode with a too low set value.
• that “Primary flow temperature at –15°C outdoor temperature” is set
sufficiently high. Increase if necessary. More can be read about this in
the chapter on The house heating curve. However, always check the
other points first.
• that the temperature reduction is set correctly. See Settings/Radiator
system.
• that the mixing valve is not in the manual position.
If the heat is not even, check:
• that the placement of the room sensors is appropriate for the house.
• that the radiator thermostats don’t interfere with the room sensor.
• that no other heat sources/cold sources interfere with the room sensor.
• that the mixing valve is not in the manual position.
CTC EcoZenith i250

General Information
Current Monitor
The CTC EcoZenith i250 has an integrated current monitor. If the system
is fitted with a current sensor, the property’s main fuses are continuously
monitored to ensure they are not overloaded. If this should happen, electric
stages are disconnected from the CTC EcoZenith.
The electrical power of the CTC EcoZenith i250 may be restricted where high
heating requirement levels are combined with, for example, single-phase
motor heaters, cookers, washing machines or tumble dryers. This may result
in inadequate heating or hot water temperatures. If the CTC EcoZenith is
restricted, “High current, elpower redu (X A)” appears in text form in the
display. Consult an electrician to determine whether the fuse size is correct
or the three phases in the house are evenly loaded.
Vent valve
Air problems
If you hear a rasping sound from the tank, check that it has been properly
bled. Turn the boiler vent valve so that any air can be evacuated. Top up with
water where required, so that the correct pressure is achieved. If this noise
recurs, call a technician to check the cause.
Unusual noise when shutting off DHW
In some cases, unusual noises may be produced by the house's pipe
system and the CTC EcoZenith i250 due to the jolts which occur when the
flow is quickly interrupted. There is no fault with the product, but the noise
may occur when older model outlets are used. More recent outlets are
often fitted with a soft-closing mechanism. If an unusual sound comes from
hard-closing dishwasher and washing machines, this can be remedied using
a shock arrestor. A shock arrestor can also be an alternative to soft-closing
water taps.
Motor protection (when heat pump is connected)
The CTC EcoZenith i250 constantly monitors the compressor’s operating
current and an alarm is triggered if the compressor is using an unusually high
current. When a fault occurs the message "Motor protect high current" is
displayed.
The cause of the fault may be as follows:
• Phase failure or mains interruption. Check the fuses, which are the
most common cause.
• Compressor overload. Call out a service engineer.
• Faulty compressor. Call out a service engineer.
• Inadequate circulation between the heat pump and boiler. Check the
heat medium pump (left pump, viewed from front). Call out a service
engineer.
• Abnormally high temperature in the brine circuit. Call out a service
engineer.
52
CTC EcoZenith i250

Don’t forget that the
radiators may also
need bleeding.

Alarm text
Description
Wrong phase order
compressor
The product’s compressor motor must rotate in the right direction. The
product checks that the phases are connected correctly; otherwise, an
alarm is triggered. In this case, two of the phases to the product need to be
changed. The power supply to the system must be shut off when rectifying
this fault. This fault generally only occurs during installation.
Alarm sensor
An alarm is displayed if a fault occurs with a sensor that is not connected or
has short-circuited and if the value is outside the sensor's range. If this sensor
is important to the system’s operation, the compressor stops. In this case,
the alarm is reset manually after the fault has been rectified. For the following
sensors the alarm is reset automatically after correction:
Sensor upper tank (B5), Sensor lower tank (B6), Sensor prim flow 1 (B1),
Sensor prim flow 2 (B2), Sensor out (B15), Room sensor 1 (B11), Room

The CTC EcoZenith i250 is designed to be fitted to an 18 l closed expansion
vessel. The expansion vessel is either fitted in the area under the tank or on
top of the product (see pictures). The expansion vessel with installation kit is
available as an accessory.

NB: If the heat pump is not connected, the
connections not being used must be capped off!
If you connect the product to an open system, the distance between the
expansion vessel and the highest placed radiator must not be less than 2.5
metres in order to avoid introducing oxygen into the system.
Note that no hot water circulation may be connected as it affects the
function of the EcoZenith and the system. If the EcoZenith i250 is connected
to another heat source, e.g. an existing boiler, the installations must have
separate expansion vessels.
Water taps
In some cases, unusual noises may be produced by the house’s pipe
system and the EcoZenith i250 due to the jolts which occur when the flow
is quickly interrupted. There is no fault with the product, but the noise may
occur when older model outlets are used. More recent outlets are often fitted
with a soft-closing mechanism. Alternatively, a shock arrestor can be fitted.
Keeping the jolting to a minimum also helps avoid unnecessary wear and
tear affecting the DHW system.

12.3 Connection to heat pump
The heat pump is connected to the top (CTC EcoZenith i250L, see figure
below) or bottom (CTC EcoZenith i250H).
The charge pump for the heat pumps is factory-installed in the
CTC EcoZenith i250L.
The CTC EcoZenith i250 L has pipes at the rear right edge for connection of
the heat pump.
The CTC Eco Air’s lower connection (5) is connected to the right connection
(2) when viewed from the front, so that water is pumped out to the heat
pump. The CTC EcoAir's upper connection (4) is thus connected to the left
connection (1).
The CTC EcoZenith i250 H heat pump is connected directly to the supplied
charge pump (3) located under the tank. The heat pump’s lower connection
(5) must be connected to the charge pump (3) so that water is pumped out
to the heat pump. The heat pump’s upper connection is connected to the
right diverting valve (viewed from the front).
Draining: A drain valve must be fitted to the EcoZenith’s left connection
(where the charge pump is mounted). It functions as drainage for both the
boiler and the radiator system.

13. Energyflex
Energyflex is a collective term that describes CTC's unique opportunity for
maximum flexibility and combining difference heat sources in a simple way.
The most common combination is a heat pump and electric boiler.
It is worth noting here that when installed the CTC EcoZenith i250 can serve
as an electric boiler alone, but it can subsequently be augmented with:
CTC EcoPart Heat Pump (ground source))
CTC EcoAir Heat Pump (air to water)
Solar Energy
The CTC EcoHeat/EcoZenith now has integrated functionality for simple
augmentation with
Solar Energy
Pool
Wood-Fired Heating
Regarding wood-fired heating:
The integrated "Differential thermostat function" control initiates the charge
from, e.g., the existing wood-fired system or fireplace when the temperature
is higher than it is in the CTC EcoHeat/EcoZenith i250
Bear in mind that it can also be a good idea to install an automatic charger
that can protect the wood-fired system from condensation, etc
If the wood-fired system needs more water than the 223 l contained in the
product, the system needs to be supplemented with an accumulator tank.
Example of wood-fired system with group
of chargers
!
Energyflex can also be used to draw energy, e.g. to heat
a swimming pool
Connecting external systems can seriously affect the EcoZenith’s operation and
performance and can therefore produce undesirable effects if the system is not
installed correctly.
If you are unsure how to make the connection, contact CTC for suggestions on
how to install the system.

System options, Energyflex
The flexibility in the CTC EcoHeat and CTC EcoZenith i250 is optimised
because the products contain functionality for five basic systems. These are:
Solar "system 1"
Solar "system 2"
Solar "system 3"
Diff thermostat function
Pool
Solar also offers the facility to recharge the drill hole or collect energy for an
extra tank, with or without a solar coil.
*The differential thermostat function can be connected to an existing PCB in
the CTC EcoHeat 400/CTC EcoZenith i250, while Solar systems 1, 2, 3 and
Pool require the product to be supplemented with the CTC Solar Control/
Expansion Card accessory.

Diff thermostat function
The differential thermostat function is used if you
want to charge your EcoHeat/EcoZenith from an
existing wood-fired boiler, a water-jacketed stove or
another cheap heat source.
The function compares the temperature in the
EcoHeat/EcoZenith and the external heat source.
Charging starts when it is warmer in the external
heat source.
NB: For certain heat sources, e.g. solid fuel boilers,
automatic chargers are recommended, among other
things to counteract condensation in the fire box.

14. Electrical installation
Installation and connection in the CTC EcoZenith i250 must be undertaken
by an authorised electrician. All wiring must be installed according to
applicable regulations. The boiler is internally connected by the factory and
set for a 5.5 + 6.0 kW power output. Depending on the country in which
CTC EcoZenith i250 is to be installed, it is available with a 400 V or 230 V
electrical connection.
Electrical connections are made behind the product's front panel. Undo
the screws on the top (2 screws), bend out and put the front to one side
(disconnect any network cables on the front printed circuit card for easier
access). The terminal blocks are located behind the electrical
connection box cover. Connection cables are inserted in the cable ducts
on the unit’s top cover, which exit at the same height as the bottom of the
electrical connections box. Sensor cables are inserted separately as far as
possible through the cable ducts to the right of the product’s top cover.
Safety switch
The installation should be preceded by an omnipolar safety switch according
to overvoltage category III, which ensures disconnection from all electric
power sources.
Circulation pump connection for radiator system
The radiator pump is connected electrically to the terminal board. Electrical
data: 230V 1N~. Internal fuse 10 A.

14.4.1 Communication
The CTC EcoAir 406-410, 520M or CTC EcoPart 406-412 heat pumps are
controlled from the EcoZenith i250. Other makes of heat pump cannot be
controlled from the EcoZenith. Communication between the products takes
place via an LiYCY (TP) communication cable, which is a 4-conductor shielded
cable, where the communication-bearing conductors are of twisted pair type.
The connection is made in the communication port on the PCB and in the heat
pump in accordance with its instruction manual.
G51 = Brown cable, G52 = white cable, G53 = green cable.

14.5 Extra low voltage protection
The following outputs and inputs have extra low voltage protection: current
sensor, outdoor sensor, room sensor, primary flow sensor, return sensor,
NR/SO, temperature sensor, level switch and PWM signals.
Connection of outdoor sensor (B15)
The sensor should be set up on the house’s northwest or north side, so that
it is not exposed to morning and evening sun. If there is a risk of the sensor
being affected by the sun’s rays, it must be protected by a screen.
Place the sensor at around 2/3 of the height of the facade near a corner, but
not under a roof projection or other form of wind protection. Do not place it
either above ventilation ducts, doors or windows where the sensor may be
affected by factors other than the actual outdoor temperature.
Connection of room sensor (B11) (B12)
The room sensor is fitted at a central point in the house, in the most open
position possible, ideally in a hall between several rooms. This is the best
position for the sensor to record an average temperature for the house.
Feed a three-conductor cable (minimum 0.5 mm2) between the heat pump
and room sensor. Then attach the room sensor securely in a position at
roughly two thirds of the way up the wall. Connect the cable to the room
sensor and EcoZenith.
!
Do not attach the
sensor cable permanently until you have
tested where the
best location is.
Connection of primary flow sensor (B1, B2) /return sensor
(B7)
Fit the primary flow sensor to the primary flow pipe, ideally after the
circulation pump. Fit the return sensor to the return pipe.
The sensing part is towards the end of the sensor (see sketch).

• Attach the sensor using the tie strap provided.
• Ensure that the sensor makes good contact with the pipe.
Apply contact paste to the front part of the sensor between the sensor
and the pipe if good contact is otherwise difficult to obtain.
• Important! Insulate the sensor using pipe insulation.
• Connect the cables to the EcoZenith’s terminal board.

Installation
14.5.1 Remote-controlled temperature reduction
The night temperature reduction function can be activated via a closed
function on the electricity remote control input, pins G33 and G34 on the
terminal board. The function can be controlled remotely using “Minicall”, for
instance.
While the input is short circuited, the temperature reduction is activated,
regardless of other settings. When the short circuit ceases, the product
returns to ordinary settings.
The size of the reduction is set in the menu: Installer/Settings/Radiator
system/Prim reduced.
NOTE: the input function can be selected according to the following:
• NR = Night reduction of temperature (time-controlled lowering of
temperature)
• SO = Shut off (compressor and power output blocked by the electricity
supplier)
• DHW = Extra hot water button (accessory)
14.5.2Current sensor connection
The three current sensors, one for each phase, are fitted on the fuse panel in
the following manner.
Each phase from the electricity distribution board supplying the EcoHeat
is channelled through a current sensor before termination at the relevant
terminal. This allows the phase current to be sensed all the time and
compared with the value set for the heat pump's load switch. If the current
is higher, the control unit drops to a lower heat output on the immersion
heater. If this is insufficient, the heat pump is also limited. When the power
drops back to the set value, the heat pump and immersion heater are
reconnected.
This means that the current sensors, along with the electronics, prevent
more power being supplied than the main fuses can tolerate.
The current sensors’ holes for cables are 11 mm in diameter.
Use at least 0.5 mm2 cable.

Installation CTC EcoAir 520M
15. Connection of CTC EcoAir 520M
heat pump
The CTC EcoAir 520M is a modulating heat pump that is fully designed to
work with the CTC EcoZenith i250L.
The following applies when installing the CTC EcoAir 520M with the
CTC EcoZenith i250 H/L:
• Powered separately. The products are switched on separately. Control
cabling only between the products.
• CTC circulation pump item no. 586988301 (7.5m HP) can be added to
handle flow requirements with normal installation.
• The heat pump strives to deliver the correct temperature to the
primary flow water. The setpoint for the upper tank or lower tank. If
there is insufficient power the compressor speed increases. When the
temperature approaches the setpoint the compressor speed reduces.
The CTC EcoAir 520M is set at the factory to automatically
vary (modulate) the compressor speed between 20 and 90
rps in cold weather and to vary it between 20 and 50 rps in
warm weather as shown in the adjoining diagram.

This function starts the calculation of the optimal charge
pump speed. The function is activated by marking
the “Auto setting charge pump” line and pressing
“OK”. While calculation is in progress, “In progress”
is displayed below the “Charge pump” line. Once
calculation is compete the new value is placed in the
“Charge pump” line, e.g. 72%

Installation
16. First start
When the CTC EcoZenith i250 is delivered, the heat pump is blocked to avoid it
being started unintentionally. EcoZenith I250 can be installed and started before
the bedrock/ground source or air/water heat pump is put into operation.
The EcoZenith i250 can also be started without a room sensor being fitted as
the curve which has been set then regulates the heating. Deselect the room
sensor in the Settings menu. The sensor can however always be fitted for the
alarm LED function.
Before first start
1. Check that the EcoZenith I250 and system are full of water and have been
bled.
(The EcoZenith i250 is bled through the safety valve on the top cover Före

Installation
First start
Switch on the power using the safety switch. The display comes on.
CTC EcoZenith i250 now asks the following:
1. Select language and press OK
2. Confirm that the system is filled with water and press OK. Press next.
3. Size of main fuse Choose between 10 and 35 A.
4. Enter the supply voltage 3x400 (1x230/3x230 apply only to export
variants)
5. Specify the maximum electric heater power. Choose between 0.0 and
9.0 kW in different steps.
This applies to electric heaters in the upper tank.
6. Select the option permitting the compressor (if the collector system is
ready or the air/water pump is already installed). When the compressor
is started for the first time, it is automatically checked that it is running in
the correct direction. An error message is displayed in the panel display
if it is rotating in the wrong direction. Switch any two phases to change
the direction of rotation.
7. Brine pump On, Auto (Auto/10d/On) (For CTC EcoHeat/EcoPart only)
Auto means that the brine pump is automatically operating at the same
time as the heat pump (factory setting).
10d means that the brine pump is running continuously during the first
10 days in order to assist with bleeding.
“On” means that the brine pump is running constantly.
8. Specify max. primary flow 1 °C for radiator system 1.
9. Specify inclination 1 for radiator system 1.
10. Specify the adjustment for radiator system 2.
11. Current sensors identified. The CTC EcoZenith i250 then starts and the
start menu appears.
12. Enter the set values in the parameter list so that the customer knows
what has been set in addition to factory settings during installation.
