2446 Fan shutdown delay
This parameter belongs to function Fan shutdown K38.
This function is used to switch off the fan’s power supply. Power supply to the fan is
released as soon as the fan’s PWM control is active or whenever there is a request for
DHW. Fan shutdown is delayed and takes place after PWM control is switched off, or
when there is no more demand for DHW. This delayed shutdown can be set via Fan
shutdown delay (2446).
During the time a request for DHW is active, the fan’s power supply also remains
released when PWM control is inactive.
Fan shutdown heating mode (2445) can be used to select whether the fan’s power
supply shall also be released when there are requests for space heating, independent
of PWM control.
