5.5.8.4 Fan control - Controller type UA 131 DD
Fan control works with the first defrost sensor of a zone and a relay.
R1.1: Evaporator sensor
R1.3: Evaporator sensor (optional in two-zone operation)
Fan1:Fancontrolrelay
The fan continues running during cooling and is stopped during defrosting. With external toggling of setpoints
from Set 1 to Set 2 - but not vice versa - the fans stop for a definable time. This is necessary to ensure trouble-

If a thermal fan delay has been set, the fan is initially not switched on after the defrosting in order not to blow
any heat into the display case. The fan relay is the normally closed (inverted) type:
the relay contact (15/16) is open when the controller switches on the fan;
the relay contact (15/16) is closed when the controller switches off the fan.
Fan relay: inverted activation
Single-zone: R1.1 acts on fan relay
Two-zone: R1.1 and R1.3 acts on fan relay
