3.Coil frost prevention Temperature control

When indoor coil thermistor detects following temperature for 90 seconds, operational frequency of compressor is controlled according to the following table.

Temperature of indoor coil thermistor	Operation frequency

50°F or more	Normal (variable)

46°F to 50°F	Raise 6Hz

43°F to 46°F	Fixed

37°F to 43°F	Lower 3Hz

	Lower 6Hz
37°F or less	Compressor is turned OFF for 5 minutes when temperature of
	indoor coil thermistor continues 37°F or less for 5 minutes or more.

The indoor fan maintains the actual speed of the moment.

4.Low outside temperature operation

If the outside temperature falls to 64°F or less during operation in COOL mode, the unit enters the low outside temperature operation mode.

(1)If the unit enters the low outside temperature operation mode, the outside fan rotation speed gets slow down.

(2)Even when the unit is in the "thermostat-off" status under the low outside temperature operation mode, the outside fan rotation does not stop.

(3)In this mode to detect the exact outside temperature the compressor turns OFF with the outdoor fan ON for 3 minutes once 1 hour; if the outside temperature rises over 64°F, the unit goes back to the normal COOL mode, and if the outside temperature is still 64°F or less, the unit stays in the low outside temperature operation mode.

(4)Dew drop prevention

When the ambient temperature thermistor RT65 reads 10°F or less, as coil frost or dew drop from indoor unit may occur, the compressor turns OFF with the outdoor fan ON for prevention of them.

WOther protections work as well as in the normal COOL mode.
