(2) Heating starting process
At the start of heating, the compressor is started by the following process. Compressor start-up
to change the 4 way valve. Capacity control returns to normal control after the end of the starting process.

< Starting process >
Compressor operates based on the required capacity at the start up, after that the target high-pressure
control begins.
*However, when the following condition (A) or (B) are satisfied, starting process is not performed.
< Conditions under which starting process is not performed >
(A) The compressor temperature 32 , when the room temperature reached to the setting temperature
