External safety circuit (K1)
Toguaranteethesafetyofthehumidicationsystem,monitoringtheoperationbymeansofasafetycircuit
isanabsoluterequirement.Toaccomplishthis,thepotential-freecontacts(250V/2A)ofexternalmonitoring

series to terminals 1 and 2.
Control or sensor signal
The control signal (signal Y) is connected to terminals 3 and 4. The air supply limit signal (signal Z) is con-
nectedtoterminals3and5.BydefaulttheCondairGSisconguredfora0…10VDCcontrolsignals.The
