Toshiba RAV-SM1100AT-E Outdoor fan control Object: SM560, Allocations of fan tap revolutions

5.Outdoor fan control (Object: SM560)

The outdoor fan is controlled by TO sensor and the revolutions frequency of the compressor (rps).

The outdoor fan is controlled by every 1 tap of DC fan control (8 taps). According to each operation mode, the fan is operated by selecting an outdoor fan operation tap in the following table based upon the conditions of TO sensor and the compressor operation (rps).

6.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.
