3. "Fan overrun" operating mode
Thefanrelayisswitchedoncontinuouslyduringthecoolinginthisoperatingmode.
The fan relay initially remains switched on when defrosting starts. The fan relay switches off if the parameter
Lüfter Überattheevaporatorsensorisexceeded.Whendefrostingisfinished,thefanrelayswitchesonagain
iftheparameterLüfteranlaufontheevaporatorisundercutagain.
Insingle-zoneoperation,onlytheevaporatorsensorR1.1isusedforthefancontrol.
BothevaporatorsensorsR1.1andR1.2areusedforthefancontrolintwo-zoneoperation.Iftheevaporator
sensor R1.2 is not attached, then only the evaporator sensor R1.1 is also used for fan control in two-zone
operation.
The fan relay does not change its state during any possibly parametrised drip time. The
parameterLüfter Überisalreadyevaluatedduringapossiblyparametrisedwaittime.
