Toshiba RAV-SM2244AT8Z-E, RAV-SM2804AT8ZG-E, RAV-SM2244AT8ZG-E Coil heating control, To ˚C

14.Coil heating control

1)This control has the function of heating the compressor by applying a current to the compressor when not operating instead using a case heater.

This control is for the purpose of preventing stagnation of the refrigerant inside the compressor.

2)Malfunction in the compressor may result if a current is not applied for a specified time before a test run after installation as was previously the case.

Similarly, starting operation after turning the power OFF and not operating for a long time also requires application of a current before starting operation, in the same manner as the test run.

3)Application of current is determined by TD and TO sensors.

When the TO sensor is defective, a backup control is automatically performed by the TE sensor. When TO sensor is defective, make a determination using the LED display of the outdoor interface board.

4)The power is turned off when TD is 30°C or more.
