Check Pins; Double Speed Of Time For The Timer; Outdoor Pcb (Printed Circuit Board) - Sanyo SPW-CR363GVH8 Service Manual

12. Check Pins

12-1. Indoor PCB (Printed Circuit Board)
If the check pins on the indoor PCB (Printed Circuit Board) are short-circuited, output operation for each unit can be
performed independently.
If the FORCED OPR pins (CN5, white) are short-circuited, the indoor unit enters the operation mode listed in the table
below.
Without connecting the remote controller, the indoor unit can be operated independently.
1 Relay 2X
2 Relay RY2
3 Electronic refrigerant control valve

12-2. Outdoor PCB (Printed Circuit Board)

If the check pins on the outdoor PCB (Printed Circuit Board) are short-circuited, output operation for each section can be
performed independently.
If the CHECK pins (CN26, red) are short-circuited after turning off the power to the outdoor unit, and the power is turned
on again, output is executed for 3 seconds for each section. After the output is completed, the outdoor unit enters the stop
mode.

4 Relay RY10
5 Relay RY6
6 Relay RY7
7 Relay RY8
8 Relay RY9
9 Relay RY3
10 Relay RY4
11 Relay RY5
If the double speed pins (TEST PIN) (CN27, yellow) on the outdoor PCB (Printed Circuit Board) are short-circuited
after the above operation, the outdoor fan and compressor operate in the cooling mode. However, if the protection
device is activated, they will enter the alarm operation mode.
NOTE
If you do not want to activate the compressor, disconnect the compressor wiring from the magnetic contactor.

13. Double Speed of Time for the Timer

If the double speed pins (TEST PIN) (CN27, yellow) on the outdoor PCB (Printed Circuit Board) are short-circuited,
the time for each delay timer on the outdoor side is shortened.
NOTE
If the outdoor unit is turned on and off repeatedly in the double speed mode, the compressor will be damaged.
So operates the double speed mode with care. (Normally set this mode to OFF.)
