1) Cooling fan control
Q
The outdoor fan is controlled by TE, TD, and TO sensors and also revolution frequency of the opera-
tion. The outdoor is controlled by every 1 tap of DC fan control (15 taps).
R
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.
S
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.
(The operation frequency differs according to the model type.)
