6.11.16 Fan
Line no. Operating line
2441 Fan speed heating max
This parameter is used to limit the maximum output in Heating mode.
Line no. Operating line
2442 Fan speed full charging max
This parameter can be used to limit the maximum output with full charging in
connection with stratification storage tanks.
Line no. Operating line
2443 Fan sp start value inst WH
To ensure quick and stable control of the required output when DHW is consumed, a
modulation start value for the instantaneous water heater can be preset.
If, due to a small control deviation, the controller calls for a lower fan speed, this start
value ensures that the fan is controlled to a lower speed. If evaluation of the control
deviation demands a higher speed, the fan is controlled to a higher speed.
Line no. Operating line
2444 Fan speed DHW max
This parameter is used to limit the maximum fan speed for DHW heating. The
parameter is OSV-compatible. With OSV, the maximum fan speed applies to DHW
heating.
Line no. Operating line
2445 Fan shutdown heating mode
Off
On
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.
Off
Function is deactivated.
On
Function is activated.
