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) Using TD sensor and TE sensor, RAV-SP180AT2-UL judges the power-on.
4) The power is turned off when TD is 86°F (30°C) or more.
REQUIREMENT
In some cases, the sound of power-ON may be heard.
It is not abnormal.
REQUIREMENT
While heating the coil, the power sound may be heard. However it is not a trouble.
5. Short intermittent operation preventive control
1) For 3 to 10 minutes after operation start, in some cases, the compressor does not stop to protect the
compressor even if receiving the THERMO OFF signal from indoor.
However it is not abnormal status. (The operation continuance differs according to the operation status.)
2) When the operation stops by the remote controller, the operation does not continue.
6. Current release control
No. of revolutions of the compressor is controlled by AC current value detected by the outdoor P.C. board so
that the input current of the inverter does not exceed the specified value.
