Wiring Error Check
 Designed to provide convenience for the system to
correct wiring errors itself.

For unclear local wiring in the case of buried/hidden
piping.

This function works by letting refrigerant flow from
port A and on onward. The indoor coil temperature is
detected one by one to check for matching between
the piping and wiring.

If wiring is corrected or change a new controller,
wiring check has to be carried out again.
Technical Training
INVERTER Y MULTI SPLIT
Wiring Error Check
For example:
If wiring from Port A is correctly connected to Room A,
but piping from Port B instead.
 After self-correction, when unit is turned ON,
OD will change the add in memory so that EXV A is
link to Port B.

Wiring Error Check

Press SW3 button to activate wiring check function:
•
•
•
The red LEDs will start blinking one after another.
The compressor is set to run at fix frequency.
Wiring to each ID unit is checked in sequence.
It takes 10~15min to complete the check and correction.
Result


Red LEDs blinking in sequence – self correction complete, unit ready to run.
• All LEDs blinking together – fail to self correct, recheck wire and piping.
•

This function is subjected to following conditions:
After unit is first turned ON, need to wait for about 30 seconds for system
initialization.
• OD ambient > 5C.
• To complete 3 minutes standby after unit stops.
• Indoor units are not having any other problem.
•
Technical Training
INVERTER Y MULTI SPLIT
Priority Room Setting

Allow user to set a particular room which takes precedence
over the operation mode of other rooms.

For example, if Room A is the priority room, when COOL
mode is selected in Room A while Room B, C & D are
operating in the following mode:
Operation mode in Room B, C & D
Status of Room B, C & D
COOL or DRY or FAN
Current operation mode is maintained
HEAT
The unit enters Standby Mode. Operation resumes when
Room A unit stops operating.
AUTO
If the unit is set to COOL mode, operation continues.
If set to HEAT mode, it enters Standby Mode.
Operation resumes when Room A unit stops operating.
Technical Training
INVERTER Y MULTI SPLIT
Priority Room Setting

This setting must be done when the unit is first installed.

Make sure setting is only done for 1 room.

Slide SW4 dip switch to the ON side for the
corresponding indoor unit to be set as priority room.
