1. Check the voltage of "CO1H"
on the remote controller.
2. Check the temp. sensor of
remtote controller.
1. Check the voltage between PIN
1 and 2 of CN-A cycle/CN-B
cycle ON the main PCB.
2. Check the temp. sensor of
remtote controller.
1. Check the voltage between PIN 3
and 4 of CN-A cycle/CN-B cycle.
2. Check the temp. sensor of
indoor pipe.
1. Check the voltage between
PIN 1 and 3 of CN-TEMP
OUT on the main PCB.
2. Check the temp. sensor of
outdoor room.
1. Check the connecting wire
between main PCB remote
controller.
2. Check the input voltage of
remote-controller.
3. Check the wiring of
remote-controller.
