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.

		ƒ When TE ≥ 24°C continues for 5 minutes, the
TE [˚C]		compressor stops.
	–2 taps / 20 sec. (Down to W1)	It is the same status as the normal THERMO
		OFF without error display.
24	Stop timer count	The compressor restarts after approx. 2 minutes
	–2 taps / 20 sec. (Down to W1)	30 seconds and this intermittent operation is not
21		abnormal.
	–1 tap / 20 sec. (Down to W1)	„ In case that the status in item ƒ generates
18		frequently, stain on filter of the suction part of
	Revolution frequency hold	the indoor unit is considered.
15		Clean the filter and then restart the operation.
	+1 tap / 20 sec
	(Up to the maximum tap of each zone)

4.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 stagnation 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 and left as it is for a long time.

3)SP80 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 outdoor LED display.

Using TD sensor and TE sensor, SP56 judges the power-on.

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