5. Short interrupted operation preventive control
1) Even when a thermostat OFF signal is received from the indoor unit, the compressor may not stop during
3 to 10 minute period after startup in order to protect the compressor.
This operation is not a trouble condition. ( The continuous operation time for compressor differs
depending on the operational status.)
2) When operation is terminated by using a remote controller, operation will not continue.
6. Electrical current release control
An AC current detection value from T10 on the control board is used to suppress the revolution number of
the compressor so that the input current of the inverter does not exceed a specified value.
4. Defrost control
1) During heating operations, defrost operations are performed when the temperature from the TE sensor
satisfies any of the conditions in the A to D zones.
2) During defrosting operations, defrost will be terminated if the temperature from the TE sensor continues
at 12°C or higher for 3 seconds or if the temperature is 7°C
≤
TE < 12°C for 1 minute.
Furthermore the defrost operation will be terminated if defrosting operations have continued for 10
minutes even if TE sensor temperature is less than 7°C.
3) After defrost operations have been reset, the compressor restarts heating operations without stopping.
