1) Cooling fan control

QThe outdoor fan is controlled by TE sensor. (Cooling: Temperature conditions after medium term)

The cooling fan is controlled by every 1 tap of DC fan control (14 taps).

RAt the activation time, although the maximum fan tap in the following table are fixed for 60 seconds, after then the fan may not rotate with high speed for several minutes because the fan is controlled by TE sensor value. It is not an abnormal status.

SWhen the discharge temperature sensor is abnormal or the sensor comes off the holder, the fan does not rotate with high speed, but a protec- tive device works.

TWhen the outdoor fan does not rotate with high speed, judge a fan error by comparing the control data in the following table with TO and TE values.

2) Heating fan control

QThis control function lowers fan tap according to TE sensor value when outdoor temperature is high.

RWhen a status TE > 20°C is detected continu- ously for 5 minutes, the operation may stop. This status does not output an error code and is assumed as usual status of thermo-OFF. The fan restarts after approx. 2 minutes 30 seconds and this intermittent operation is not a trouble.

SIf the status in item R is frequently found, it is considered that the filter of suction part of the indoor unit is dirty. Clean the filter and restart the operation.

TThis control function does not work for 30 min- utes after activation, 1 minute after defrosting, and during defrost operation.
