1. Introduction
Regulator DX4102 (in next text regulator or device) is determined to regulation system consists
of solar collectors and a warm exchanger to gain warm energy and propagate it to the other systems.
Warm exchanger could be for example boiler, water basin or central heating system.
Regulator distributes warm carrying fluid to warm exchanger using actuator (pump) according to
set up temperature.
Device is equipped with timing facilities (programmable), which could use subsidiary energy
source (electric heating alternatively gas kettle-drum), providing heat limitations in loop.
Alternatively device can control secondary loop pump with time delay function.
Device is able to count up the energy given to warm exchanger.
DX4102.G behavior can be set up according to requested system parameters - "programming",
Programming uses four keys and Liquid Crystal Display (LCD) located at front panel of the device.
There can be found Light Emitting Diodes for power supply indication, system failure.
Regulator is equipped with current loop for data communication with Personal Computer.
Software named “EkoSolar” allow user to watch, modify and archive all important data and solar
system parameters.

2. Control fundamentals
2.1 Regulation fundamentals
Regulator is one-loop (one-channel) differential regulator. Controlled system consists of solar
collectors, heat exchanger (A) and actuator, which distribute warm liquid to exchanger.
Regulator in a forever cycle watches temperatures at the exchanger and compares it with the
requested values. To pump warm liquid to exchanger two conditions must be fulfilled (in next text
abbreviated start pump conditions):
1. Insufficient heat exchanger temperature - measured exchanger temperature must be lower
than requested temperature (see "Menu-Temp"), set hysteresis 1 K.
2. Sufficient collector energy - collector temperature must be higher over minimum difference
"DeltaON" (see "Menu-Delta") than exchanger temperature to start pump. Pump stops if
difference falls below "DeltaOFF" - see 2.1. Parameter "Delta" is needed because of thermal
loss in piping between collector and exchanger.

Tex
t [sec]
Fig.1 Pump condition – sufficient collector energy
In case the pump conditions are fulfilled (exchanger has insufficient temperature and in collector
has sufficient energy), the loop will be switched on e.g. warm liquid will be pumped through this
loop. In case the loop has not fulfilled conditions for loading warm, pump stops.
Providing the loop have defined subsidiary energy source ("Menu-Service-Aux.Out=Heating")
and exchanger have insufficient temperature, but collector will not have sufficient energy for this
loop, it will be enabled subsidiary heating (see chap 2.6), that is time and temperature dependent.
2.2 Pump performance regulation
Device can control the pump performance with pulse-width modulation – to decrease
performance the pump is switched of for some tens of milliseconds. Performance regulation is
enabled if "Menu-Service-PWMmod" is set up less than 100% (minimal 20%).
Pump performance is controlled (see chap. 2.2) if temperature sinks (collector to exchanger)
below DeltaON level. The performance is decreased to Pmin till an average value of DeltaON and
DeltaOFF, than it stays on Pmin till difference falls below DeltaOFF

2.3 Collector temperature sensing
Collector temperature sensing is made by fixing collector sensor to collector corpus (see menu
Service-Sensor) and collector loop is "drain-back" type ("Sensor=Drain").
Drain-back system – is created of collector loop with FILL-in and FILL-out liquid (using solar
fluid tank) after an activation condition is fulfilled (collector temperature is over "DeltaT" value
greater than exchanger temperature). If it is true the pump is started for defined time A at full power
(the liquid is transported to collector fields), then the power is slowed down (necessary to keep the
flow level) for fixed interval B to get system niveau. In the end the collector loop is set to normal
process. After the finishing, (loading condition is false), the warm liquid is filled out from the loop
to fluid tank.
2.4 Collector overheating
If exchanger is full loaded (has enough energy) and the sun shines it could happen collector
overheating. That is why regulator is equipped with „overheating protection“ which can be
activated in menu (see chap. 3.2). As the collector temperature increases over 105 °C the primary
pump start running till the exchanger temperature reaches MaxTexc (see menu Service) or collector
temperature sinks below 100 °C. The overheating check stops if collector temperature increases
over 120 °C and will be started again if collector temperature falls below MaxTexc. This is
reasonable if the power (230V) is missing for some time (power failure).
2.5 Auxiliary output
Device is equipped with special output (X/Y), which can be used for cooperation with exchanger
or like standalone timer output. In case of exchanger the auxiliary output is used for:
1. subsidiary heating (see chap. 2.6)
2. secondary pump management (see chap. 2.7)
Stand alone timer output - non periodic timer – time window are give by table ( see "MenuTimer"). When configuring use of auxiliary output (see Servis – chap. 3.2) firstly the exchanger is
chosen then the way of its using (heating, secondary pump) and after the necessary parameters are
set.
2.6 Subsidiary energy source
Device is equipped with time functions ("Menu-Timer"), which is used to rank auxiliary
(subsidiary) energy source (electrical heating or gas kettle) for insufficient exchanger heat ("MenuService-Aux.Out=A-Aux.Out=Heating"). Auxiliary heating will be activated if (all conditions must
be fulfilled):
3. the time window condition is true, see menu "Timer"
4. the exchanger temp. is lower than start temp. (see "Servis-Aux.Out-...-Temp ON")
5. the exchanger (that with auxiliary heating) is not just being selected for warm loading
Auxiliary heating will be switched off, if some of conditions 1. and 3. is false, or the exchanger
temperature is higher than stop temperature (see "Servis-Aux.Out-...-Temp OFF"). There is left a
possibility to sense temperature in exchanger with another sensor which is fixed in top of
exchanger height - see example in Fig. 2 sensor Sh). Physically sensor is connected to S4
position.(see chap 4.2). This function will be activated automatically if sensor is present.
Aux.Out='–', then output XY will be controlled according to item "Timer", it means it is not bound
to loop conditions.
Auxiliary energy source will be automatically switched off at High Tariff (energy cost is
expensive), if the digital input is set to "Hi.Tarif" (viď "Service-Typ Inp"=" Hi.Tarif ") and
corresponding digital input is shorted.

2.7 Secondary loop pump
Regulator is able to use a secondary loop pump for a exchanger "Menu-ServiceAux.Out=Sec.Pump". If this is true then this output is is controlled together with corresponding
primary loop and it is stopped with preset time delay "Menu-Service-Aux.Out-...-PostPump".
Providing that exchanger sensor is localized at the pipe of secondary loop, the measured
temperature is real only for fluid circulating. That is why the regulator manages temperature check
function "Service-Aux.Out-...-CheckTem", where the regulator starts fluid pumping in a given
period "Service-Aux.Out-...-CheckTem-per", for a given interval "Service-Aux.Out-..
CheckTem- on", and it is enabled only if "sunshine" is set up (see chap.2.3
2.8 Regulation failures behaviour
If the sensor failure is found regulator behaves in a following way:
●
Collector sensor failure – warm liquid does not stop running (till the fault removing)
Exchanger sensor failure – the warm carrying fluid is pumped out till sensor malfunction
is removed, but only if collector temperature is higher than 60°C
●
Subsidiary sensor failure (S4) – subsidiary heating takes as reference value exchanger
sensor value (S2)
●
Return fluid sensor failure – temperature difference will be set 0 K, it means no instant
power (a energy will not be accumulated).
●
2.9 Energy measuring
Regulator can calculate the energy gained from collector. Energy is counted according the formula:
Q= c. m. dT, where c is relative warm capacity, m is mass and dT is temperature difference warm
carrying fluid (market name Solaren).
Fluid mass is evaluated as m= q. V, where V is volume and q is pumped fluid density (the value
is temperature dependent). The volume is either measured by flow-meter (see chap. 3.2) either
counted out from time of fluid flow and given flow per a minute.
The temperature difference is given like collector to exchanger output temperature (return fluid
sensor needed) or it is fixed difference set by DiffTemp (see chap.3.2). For the second case the
measuring is for informative purpose only.
Relative warm capacity and fluid density is assumed for SOLAREN (non diluted) !
Energy is counted up as cumulative number increasing for each period. Counter can be cleared
manually by user see “Service-Energy-Clear Ac” or “Records-Counter-date nul”. After reaching
10000 kWh it is cleared in automatic way. Day registers (32 days backward) - keep energy for each
day. The records can be seen in “Records” menu (chap.3.2).
Instant collector power represents (gained) energy amount per fixed period. Periode is given as
the delay between two flow-meter pulses or is set fixed one minute.

4.3 Installation instructions
An installation of the device should be made according to recommended application scheme
keeping following rules:
1. Firstly sensors, then actuators and in the end power line. For sensors is recommended
twisted pair line (MK 2x0.75/TP 03/41/MTP 226/70), keeping distance from power wires
(min.30 cm) and shield connect to PE wire.
2. Before screwing wires to terminal, put the sleeve endings to the end of the wires
3. Just before power supply connection check all input and output wires (sensors, actuating
terms) for disconnection or short-circuit
4. Turn on the safety fuse and test function of actuators in manual mode
5. Check measured temperature values at collector, then in the loops and set initial system
parameters.
4.4 PC connections
Device offers possibility for connection to serial port of personal computer. This connection
enable user to:
∗ comfortable set up all parameters of regulation
∗ not limited keeping records of gained energy
∗ watch regulation process from the living room „sofa“ and supervisor regulation
From the hardware side of connection, there is a necessity for communication (physical layer
converter for RS232 <=> 20 mA current loop) converter DX 5220, which is connected with two
wires to connector field (P+, P–). Keep polarity during connection, right connection forces LED in
DX5020 to light (pins of DX5020 should have about 2.7V), wrong connection (0,7V).
