2.30 min. after the unit is stopped, pre-heat control is turned ON for 15 or 30 min. and turned OFF for 30 min." This is repeated as shown in the graph until the breaker is turned OFF.

When outside temperature is 68 °F or below, pre-heat control is ON for 30 min."

When outside temperature is 69.8 °F or above, pre-heat control is ON for 15 min."

NOTE: When the unit is started with the remote controller, pre-heat control is turned OFF."

Compressor uses 50 W when pre-heat control is turned ON.

2. Coil frost prevention

The compressor operational frequency is controlled to prevent the indoor heat exchanger temperature from falling exces- sively.

Compressor is turned OFF for 5 minutes when temperature of indoor coil thermistor continues 37.4 °F or less for 5 min- utes or more.
