4. "Delay after the defrost" operating mode
The fan relay is switched on continuously during the cooling in this operating mode. The fan relay switches off
at the start of a defrost. The fan relay remains switched off during the defrost. When the defrost is finished, the
fan relay switches on again if the parameter Lüfterverzöger on the evaporator is undercut again.
Insingle-zoneoperation,onlytheevaporatorsensorR1.1hastofallbelowthevalueofLüfterverzöger so that
the fan relay is switched on.
Intwo-zoneoperation,bothevaporatorsensorsR1.1andR1.3mustfallbelowthevalueofLüfterverzögerso
that the fan relay is switched on again. If the evaporator sensor R1.3 is not attached, then the fan relay is also
only controlled via R1.1 in two-zone operation.
Thefanrelayisswitchedoffduringanypossiblyparametrisedwaitordriptime.TheparameterLüfter
Überhasnoeffectinthisoperatingmode.
