3-2) Heating fan control
The outdoor fan is controlled by TE sensor, TO sensor and the operation frequency.
(Control from minimum W1 to maximum (according to the following table))
For 3 minutes after the operation has started, the maximum fan tap corresponding to the zone in
the following table is fixed and then the fan is controlled by temperature of TE sensor.

When TE ≥ 75.2°F (24°C) continues for
5 minutes, the compressor stops.
It is the same status as the normal
THERMO-OFF without error display.
The compressor restarts after approx.
2 minutes 30 seconds and this intermit-
tent operation is not abnormal.
In case that the status in item
generates frequently, stain on filter of
the suction part of the indoor unit is
considered. Clean the filter and then
restart the operation.
