2) Heating fan control
Q
This control function lowers fan tap according to
TE sensor value when outdoor temperature is
high.
R
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.
S
If 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.
T
This control function does not work for 30 min-
utes after activation, 1 minute after defrosting,
and during defrost operation.
Control for fan tap by outdoor temperature in normal operation
1) Cooling fan control
Q
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).
R
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.
S
When 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.
T
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.
