The blowing air volume is controlled as follow:
1. When strong wind blows at outdoor side, the operation of heat pump continues with the fan motor stopped.
2. Whether the fan is locked or not detected, and the operation of heat pump stops and an alarm is displayed if the fan is
locked.
3. According to each operation mode, by the conditions of outdoor temperature (TO) and compressor revolution, the
speed of outdoor fan shown in the table is selected
008 size
1. The outdoor fan is controlled by TE, TD, and TO sensors and also revolution frequency of the operation. The outdoor is
controlled by every 1 tap of DC fan control (15 taps).
2. Only during 60 seconds after the operation has started, the fan is fixed with the maximum fan tap which corresponds to
the zone in the following table. After then the fan is controlled by TE sensor temperature.
3. Considering a case that TE sensor has come out of the holder, the fan is controlled so that revolution frequency of the
fan increases regardless of TE if temperature of TD sensor has risen.
