1) The pattern 1
[Control condition] Normally, the compressor operation frequency is raised in following start pattern.
[Control contents]
a) It starts the compressor at 55rps as target frequency.
b) Compressor speed acceleration fi nishes when the pressure diff erence becomes bigger than 0.34MPa in heating or
when the low pressure reaches 0.8MPa in cooling.
c) At 30 seconds after starting compressor, the target frequency changes to
A
rps and compressor is kept operation at
A
rps as fi xed frequency for
B
minutes.

2) The pattern 2
[Control condition] The initial start-up of compressor after turning the power source ON
[Control contents] According to the operation mode and the outdoor air temperature (Tho-A), the outdoor unit starts the
compressor with the following control.
a) It starts the compressor at 55rps as target frequency.
b) Compressor acceleration fi nishes, when pressure diff erence becomes bigger than 0.34MPa in heating or the low
pressure becomes 0.8MPa in cooling.
c) At 30 seconds after starting compressor, the target frequency changes to A rps and the compressor is kept operation
at
A
rps as fi xed frequency for
B
minutes.
