(a) Compressor protection start I
[Control condition] Normally, the compressor operation frequency is raised in this start pattern.
[Control contents] (i) Starts with the compressor’s target frequency at
A
rps.
However, when the ambient air temperature (Tho-A) is 35°C or higher during cooling/
dehumidifying or the indoor return air temperature (ThI-A) is 25°C or higher during heating, it
starts at
C
rps.
(ii) At 30 seconds after the start of compressor, its target frequency changes to
B
rps and the
compressor is operated for 2 - 4 minutes with its operation frequency fixed at
B
rps.

(b) Compressor protection start III
[Control condition] Number of compressor starts is only 1 counted after the power supply breaker ON.
[Control contents] Operates by selecting one of following start patterns according to the operation mode and the
outdoor air temperature (Tho-A).
(i) Low frequency operation control during cooling/dehumidifying
[Control condition] Upon establishing the conditions of compressor protection start III, the low frequency
operation control is performed during cooling/dehumidifying.
[Control contents] a) Starts with the compressor’s target frequency at
A
rps. When the outdoor air temperature
(Tho-A) is 35°C or higher, it starts at
C
rps.
b) At 30 seconds after the compressor start, the compressor’s target frequency is changed to
B
rps and the compressor’s operation frequency is fixed for 10 minutes.

(ii) Low frequency operation control during heating
[Control condition] When the conditions of compressor protection start III are established and one of following conditions
a) is satisfied, the low number of revolutions operation control is performed during heating.
a) At 30 minutes or more after turning the power supply breaker on
[Control contents] a) Starts the compressor with its target frequency at
A
rps. However, when the indoor unit
return air temperature (ThI-A) is 25°C or higher, it start at
C
rps.
b) At 30 seconds after the start of compressor, the compressor’s target frequency is changed to
B
rps and the compressor’s operation frequency is fixed for 10 minutes.
