1)Cooling fan control

•The 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).

‚At 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.

ƒWhen 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.

„When 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

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

‚When 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.

ƒIf the status in item ‚ 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.

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