Air outlet
: Setting before communication error occurs
Air inlet
: Setting before communication error occurs
Blower fan speed
: HI
Set temperature
: Setting before communication error occurs
- If a communication error exists between the front air control's CPU and the ASIC, the air conditioning system is controlled under the following conditions:
Compressor
: Control is normal operation
Air outlet
: Control is normal operation
Air inlet
: Control is normal operation
Blower fan speed
: Control is normal operation
Set temperature
: Control is normal operation
