2)Heating fan control

Q The outdoor fan is controlled by TE sensor, TO sensor and the operation frequency. (From Min. W1 to Max. are controlled according to the following table.)

R During 3 minutes after start-up, the fan is fixed

with the maximum fan tap corresponding to zone in the following table. After then the fan is controlled by temperature of TE sensor.

S If status, TE > 24°C continues for 5 minutes, the operation stops. This status is same to the usual Thermo-OFF which has no alarm display, and the fan restarts after 2 minutes and 30 seconds. This intermittent operation is not abnormal.

T When the above status R occurs frequently, it is considered that the filter of suction part of the indoor unit is stain. Clean the filter and then restart the operation.

(The operation frequency differs according to the model type. The case of SM1102 is shown in the table below.)

	Temp. range	Below 33 Hz	Above 33 Hz below 51 Hz	Above 51 Hz

	10°C < TO	W7	W8	W9
Maximum	5 < TO < 10°C	WA	WB	WF
Maximum	TO < 5°C	WF	WF	WF
	TO < 5°C	WF	WF	WF

	TO error	WF	WF	WF

5.Coil heating control

1)This control function heats the compressor by turning on the stopped compressor instead of a case heater. It purposes to prevent slackness of the refrigerant inside of the compressor.

2)As usual, turn on power of the compressor for the specified time before a test run after installation, otherwise a trouble of the compressor may be caused. As same as a test run, it is recommended to turn on power of the compressor beforehand when starting operation after power of the compressor has been interrupted for a long time.

3)A judgment for electricity is performed by TD and TO sensors. If TO sensor is defective, a backup control is automatically performed by TE sensor. For a case of defective TO sensor, judge it with the outdoor LED display.

4)Coil heating is controlled by TD and TE sensor.

5)For every model, the power is turned off when TD is 30°C or more.
