Operation

Heatingmode operation

Operating frequency of compressor depend on the difference of the temperature (= compressor off temp. - intake air temp.)

Compressor off temp. = setting temp.+3.0°C

on temp. = setting temp.

If compressor operates at some operation frequency, the operating frequency of compressor cannot be changed within 30 seconds.

Condition of compressor turned off

-When intake air temperature reaches +3°C above the setting temperature.

Condition of indoor fan turned off

-While in compressor on:indoor pipe temp. < 30°C

While in defrost control, between the indoor and outdoor fans are turned off.

Compressor 2minutes delay

-After compressor off, the compressor can restart minimum 2 minutes later.
