[2] FUNCTIONS
1. FREQUENCY CONTROL
2. OVER CURRENT PROTECTION
1) AC current peak control
DC over current detection, AC over current detection To protect
against over current due to sudden change in load, the compressor is
stopped if 55A DC is exceeded in the DC section. If the set value of
AC current is exceeded in the AC section, the compressor is stopped.
90 seconds after the compressor has been stopped, another starting
try will be made. Three retries are allowed. On the fourth retry, a complete stop request signal is sent to the indoor unit, and the outdoor unit
will remain stopped until the indoor operation is stopped. DC over current is detected by the power module. AC over current is detected by
CT1, on the outdoor PWB.
Cooling mode
16.5A
Heating mode
16.5A
2) Prevention control of outdoor heat exchanger overheating
If the temperature of the outdoor heat exchanger exceeds the overheating prevention line 1or 2 during cooling, the operating frequency is lowered by approximately 5 to 15Hz. After that, the
frequency is lowered approximately 5Hz once every 60 seconds or
approximately 15Hz once every 120 seconds. When the temperature of the outdoor heat exchanger goes below the overheating
prevention clear line, the frequency is raised by approximately 5Hz
once every 60 seconds, and normal operation is restored. If the frequency is lowered to minimum frequency without the temperature
of the outdoor heat exchanger decreasing and this condition lasts
for 1 minute, the compressor will be stopped.

3. COMPRESSOR PROTECTION CONTROL
If the temperature of the compressor exceeds 113C, the compressor
is stopped. In this case, the outdoor fan is not stopped until the temperature of compressor drops below 99C. In 90 seconds after the
compressor is stopped, if the temperature is below 90C, another
starting try will be made. Three retries are allowed. On the fourth retry,
a complete stop request signal is sent to the indoor unit, and the outdoor unit will remain stopped until the indoor operation is stopped.
Lower 5Hz once every
60 seconds
Lower 15Hz once
every 120 seconds
4. POWER TRANSISTOR MODULE PROTECTION
3) Prevention control of compressor overheating
If the temperature of the compressor exceeds approximately 108
C, the operating frequency is lowered approximately 5Hz. After
that, the frequency is lowered approximately 5Hz once every 60
seconds. When the compressor temperature drops below approximately 108C, the frequency is raised approximately 5Hz once
every 60 seconds, and normal operation is restored. If the frequency is lowered to minimum frequency without the temperature
of the compressor decreasing, and this condition lasts for 1 minute,
the compressor will be stopped.
If the temperature of the chips in the power transistor module exceeds
100C, the compressor is stopped. In this case, the outdoor fan is not
stopped until the temperature of power module drops below 85C. In
90 seconds after the compressor is stopped, if the temperature is
below 85C, another starting try will be made. Three retries are
allowed. On the fourth retry, a complete stop request signal is sent to
the indoor unit, and the outdoor unit will remain stopped until the
indoor operation is stopped.
5. SERIAL SIGNALS
4) Prevention control of indoor heat exchanger overheating
Serial signals consist of all 96-bit signals. If the condition as outdoor
unit unable to receive a serial signal from the indoor unit continues for
30 seconds, it closes the expansion valve which corresponds to the
room which can not be communicated. If all indoor units can not communicate with the outdoor unit, the compressor is stopped.
Two minutes after room several decrease If the temperature of any
of indoor heat exchangers exceeds the overheating prevention line
1 or 2 during heating, the operating frequency is lowered to minimum frequency. When the temperature of all of indoor heat
exchangers go below the overheating prevention line 1, the frequency is raised by approximately 5Hz once every 60 seconds,
and normal operation is restored. If the condition that the frequency
is minimum lasts for 2 minutes, the compressor will be stopped.
6. THERMISTOR OPEN OR SHORT
When compressor, heat exchanger, outdoor thermistor, suction thermistor (CN8A) are in OPEN or SHORT condition, even if they are in
the condition which an operation signal is transmitted from indoors, the
compressor will not start. If any suction thermistors (CN8C) become
OPEN or SHORT resistance, the protective procedure will work only
for the cycle corresponding to the malfunctioning suction thermistor.
<when normal >
If the temperature of any of indoor heat exchangers exceeds the overheating prevention line 1 or 2 during heating, the operating frequency
is lowered by approximately 5 to 15Hz. After that, the frequency is lowered approximately 5Hz once every 60 seconds or approximately
15Hz once every 90 seconds. When the temperature of all of indoor
heat exchangers go below the overheating prevention line 1, the frequency is raised by approximately 5Hz once every 60 seconds, and
normal operation is restored. If the condition that the frequency is minimum lasts for 2 minutes, the compressor will be stopped.

“Mis-wiring check” is conducted by detecting the indoor heat
exchanger temp. For example, when the expansion valve for only
room A is open, and the wiring is correct, the indoor heat exchanger
temp for room A will reduce. If the wiring is incorrect, the indoor heat
exchanger temp for a different room will reduce.

9. PUMP DOWN SWITCH
When the PUMP DOWN SWITCH (SW1) is pressed for 5 seconds or
more, the total A/C system will start its TEST RUN automatically and
the compressor frequency will be 55 Hz. When operating only the outdoor unit (cooling 55 Hz fixed mode) To make only the outdoor unit run
in cooling mode, and apply a voltage of 230 V AC to N and 1 on the
terminal board and push the pump down switch. (SW1) (Avoid operating the outdoor unit alone for long periods of time.)

10. CONTROL OF COMPRESSOR OR AND EXPANSION VALVE
For 90 seconds after turning on the AC power, the compressor will not
be activated even if indoor units request the compressor to do so. If
the compressor receives a request from one or more indoor units after
90 seconds have passed, it will be turned on and the expansion valve
corresponding to the requesting indoor unit will be opened. When the
indoor unit of a room requests for the cooling operation to the outdoor
unit and it runs responding to the request, requests for the heating
can't be accepted if the indoor units in other rooms send individual
requests. If the indoor unit in another room sends a request for the
heating operation, the operation lamp and timer lamp of the indoor unit
in that room start flashing in turn to inform that the unit is in the standby
mode. If the operation in one room is stopped while the indoor unit in
another room is in the stand-by mode, the operation mode requested
by the indoor unit which is now in the stand-by mode will be accepted.
At this time, the compressor will be temporarily stopped to switch the
four- way valve and restart after 90 seconds. During the cooling or dry
operation, the expansion valve corresponding to the indoor unit that is
not running is closed. Therefore, the refrigerant will not flow into those
units.However,if the heating operation is in progress, it is possible that
it flows into indoor units which are out of operation depending on the
cycle conditions. As a result, the indoor exchanger may be heated up
even if it is not activated. This is not abnormal. When the operations in
all rooms are stopped, the compressor is off and the expansion valves
in all rooms are fully opened.
The outdoor fan is s topped
The operating frequency is as shown in the table below.

for 5 minutes 3900 rpm
after that 3700 rpm
4) Defrost stop
When defrosting time exceeds 10 minutes When the temperature
of the outdoor heat exchanger rises above approximately 15C
Defrost stop is determined by either of the above conditions, and
the compressor is s topped. At the same time, the outdoor fan go
ON. The compressor is reactivated in the heating cycle 1 minutes
after it was stopped, and normal control resumes.
Defrosting begins during heating if the conditions for compressor
operation time and outdoor heat exchanger temperature are met.
When defrosting begins, the indoor and outdoor fans stop. Defrosting stops when the temperature of the outdoor heat exchanger
goes above approximately 15C or defrosting time exceeds 10 minutes.

4. MISWIRING CHECK
8) Fully open the stop valve (gas side) with hexagon socket screw
key. Turn all the way up to contact.
Miswiring check must be performed after installation, reinstallation and
service. This multi-type air conditioner is designed with a WIRE
CHECK SWITCH on the outdoor unit, and miswiring of unit-to-unit wiring will be self-corrected by microcomputer. Miswiring check may not
be performed when the outdoor temperature is below 5.
9) Disconnect the gauge manifold hose from the service port.
10)Replace the service port cap and both valve shaft caps tightly. Turn
until the torque suddenly increases. Now tighten a 1/6-turn more.
NOTE: *
*
Use a gauge manifold and hoses exclusive for R410A.
1) Complete the unit-to-unit wiring/piping and perform the air removing of the pipes. Turn the electrical circuit breaker ON. Before turning the circuit breaker ON, make sure no one is working on the
indoor units installation. Electrical shock or injury may occur.
After air removal, check the tube connections for gas leak
using a leakage detector or soapy water. Regarding leakage detector, use high-sensitivity type designed specially
for R410A.
2) Check that all LED (LED1, 2, 3, 4) on the display board unit are
flashing synchronously in a slow (one flash per second) cycle. If
either one or more of all LED is/are kept lighted on, check and correct the wrong wirings among, N, 1, 2, terminals so that all LED will
flash slowly, showing normal condition.

3) Press the WIRE CHECK SWITCH (SW2) on the display board unit
for 5 seconds or more. The flashing of all LED will change. Mis-wiring (mis-piping) check will start and the indoor and outdoor units
will start operating. (The red operation lamp on the indoor unit will
flash, and three BEEP will be emitted.) Miswiring of unit-to-unit wiring will be self-corrected.

4) Wrong piping works cannot be corrected, and will be detected as
an error. When an error is detected during checking, all LED will
show triple flash for eight times. The indoor and outdoor operation
will stop. Turn the circuit breaker OFF and check and correct the
miswiring (mispiping)*. After correction, return to step 1 and repeat
the miswiring (mispiping) check again. If error is still detected, or
other types of LED signal should be indicated, please contact a service technician. (Refer to wiring diagram attached inside the outdoor unit cabinet for self diagnosis signal.)

5) All LED (LED1, 2, 3, 4) will flash synchronously in a slow (one flash
per second) cycle when miswiring (mispiping) check is completed
with no error detection (3–6 minutes), and the operation of indoor
and outdoor units will stop. (The red operation lamp flashing on the
indoor unit will go off.)
3. Pump down
(Pump down is adopted in the case of unit removal for reinstallation,
abandonment, repair etc.) Pump down is to collect the refrigerant into
the outdoor unit by control of the stop valves and the compressor.
6) Place the control box cover back in the reverse order.
1) Turn the circuit breaker on.
*Correction points on error detection
2) Check that all LED (LED1, 2, 3, 4) on the display board unit are
flashing synchronously in a slow (one flash per second) cycle.
a) Are all piping the total multi air conditioner system connected?
b) Are the stop valves open?
3) Stop the air conditioner operation.
4) Remove both valve shaft caps of the stop valves.
5) Press the PUMP DOWN SWITCH (SW1) on the display board unit
for 5 seconds or more. The indoor/outdoor unit will start operation
in the pump down mode. (the OPERATION lamp on the indoor unit
will flash and three BEEP will be emitted.)
6) After 5 – 10 minutes, fully close the stop valve (liquid side) by turning the hexagon socket screw key clockwise.
7) After 2 – 3 minutes, immediately close the stop valve (gas side)
fully.
9) Replace the service port cap and both valve shaft caps tightly.
NOTE: Wait more than 90 seconds after finishing pump down, and
turn off the circuit breaker off.
