Power transistor Used to troubleshoot DC
check compressor. Inverter waveforms
are output without wire connections
28 to the compressor. It is useful to
determine whether the relevant
trouble has resulted from the
compressor or inverter PCB.
Capacity priority Cancel the low noise level control if
setting capacity is required while low noise
29
operation or night-time low noise
operation is in progress.
Demand 1 Used to make a change to the
setting targeted power consumption level
when the demand 1 control signal
is inputted.
30
Demand 2 Used to use a targeted power
31 setting current level when the demand 2
control signal is input.
Normal demand Used to set permanent demand 1
32 setting or 2 control without inputting any
external signal.
Indoor fan tap Indoor fan speed is limited to L tap
setting depending on connection capacity
and outdoor air temperature (Ta).
Indoor condition A: Temperature
difference average of (indoor air
temperature – set temperature) is
less than 1.5°C (2.7°F).
Indoor condition B: Temperature
difference average of (indoor air
temperature – set temperature) is
3°C (5.4°F) or more.
