The indoor control board is failure
The failure is detected when the room temperature sensor broken or shorted over 5 sec.
The failure is detected when the temperature sensor of heater exchange broken or shorted over 5 sec.
The failure is detected when each setting data is not match after the EEPPOM self-check two times.
The failure is occur when the grounding signal is not detected after the appliance power ON.
7-2. Test the jumper terminals
Note:
When the whole machine is powered up, if the external unit does not work, to rule out the
communications failures, adopt screening method such as short circuit on the jumper terminals to see if
the external unit can be started normally or similar method.
