When the power is restored to a unit, a reset is caused (from pressing the reset button), or a watchdog resets the unit, the compressor is kept turned OFF for a certain amount of time. When cooling mode (for Normal and Heat-Pump systems) or heat mode (for Heat-Pump systems) selected on a thermostat calls for compressor usage, the short cycle protection delay will prevent the compressor from turning ON and OFF constantly due to the user changing thermostat settings.
In cooling mode (for Normal and Heat-Pump systems) or heat mode (for Heat-Pump systems) with fan set to ON: When the thermostats signals to turn ON the compressor (after it has signaled to turned the compressor OFF), the fan remains ON and compressor turns ON approximately in 5 minutes (This is a compressor short cycle delay , it can vary by system).
The compressor may turn ON within 5 minutes, if it has remained OFF for some time during the use of another mode (the time satisfies part the short cycle protection delay).
The Clicksav device controls the following: If the thermostat CSCD is bypassed (advance technical diagnosis) or the reset button of the Clicksav device is pushed after the compressor has turned ON, both fan and compressor will be OFF. The fan may turn ON within 30 seconds from restart. The compressor turns ON within 3 minutes afterwards.
Note: thermostats may vary their own delay during the process of switching to cool from heat or OFF mode (this includes reaching the set temperature in the room) .
In automatic mode, this may affect timing and whether the fan turns ON before or at the time the compressor turns ON. If the fan is at least 30 seconds OFF, it may turn ON afterwards regardless of the status of the compressor.
