Parameter Meaning
Fan function (see picture above)
0: fan runs with relay
1: fan runs continuously except for defrosting (relay
2: fan runs during cooling (relay
Run-up/run-down delay of fan (Fan running function)
has the hysteresis F.Hy, remains generally locked during drip-off time.
off: no run-up/run-down delay (relay
on: run-up/run-down depends on the evaporator temperature
Run-up delay:
The fan only starts running when the evaporator temperature goes below
the fan setpoint F.SP by more than the amount of the hysteresis F.Hy (see picture).
Run-down delay with F.Fu=2
The fan keeps on running until the evaporator temperature
exceeds the fan setpoint F.SP .
Fan setpoint
Influences the running of the fan, depending on the evaporator temperature.
If it is set low enough, this will prevent any unnecessary distribution of warm air and
support the distribution of cold air in the cold store.
Fan setpoint hysteresis
The hysteresis is below the selected fan setpoint and,
consequently, influences the run-up/run-down behavior of the relay
