3-1) Cooling fan control

•The outdoor fan is controlled by TL sensor, TO sensor and the operation frequency. The outdoor fan is controlled by every 1 tap of DC fan control (14 taps).

‚Only for 60 seconds 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 TL sensor.

∗ : WB for SP110

•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.

ƒWhen TE ≥ 24°C continues for 5 minutes, the compressor stops.

It is the same status as the normal thermostat- OFF without error display.

The compressor restarts after approx. 2 minutes 30 seconds and this intermittent operation is not abnormal.

„In case that the status in item ƒ generates frequently, stain on filter of the suction part of the indoor unit is considered.

Clean the filter and then restart the operation.
