3. Operating mode "overrun"
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thedefrostiscomplete,thefanrelayIsswitchedon
again if the parameter Lüfterverzöger is undercut again at the evaporator.
Only the evaporator sensor R1.1 is used for fan control in single-zone operation.
BothevaporatorsensorsR1.1andR1.3areusedforfancontrolintwo-zoneoperation.Iftheevaporatorsensor
R1.3 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.
