13. Fan motor operation and compressor protection
Fan motor operation :
1.When the temperature in Comp. sensor is lower than 20㷄;
Fan motor turns off with the power supplied 㸢 Turns on when the
temperature in Comp. sensor is higher than 80㷄 㸢 Turns off when
the temperature in Comp. sensor is lower than 20㷄 㸢 Turns on
when the temperature in Comp.sensor is higher than 80㷄
2. When the temperature in Comp. sensor is lower than 20㷄;
Fan motor turns on with the power supplied 㸢 Turns off when the
temperature in Comp. sensor is lower than 20㷄 㸢 Turns on when
the temperature in Comp. sensor is higher than 80㷄
Compressor protection:
(during Fan Lock)
Compressor stops operation when the temperature in Comp. sensor
reaches 100㷄. (Compressor protection)
Starts operation again when the temperature in Comp. sensor is lower
than 65㷄.
