operation via external signal or automatically
via a CHANGEOVER 230V AC input IN2.
Applies to 2 pipe system.
Night reduction / setpoint offset
Obtained by setting DIP-3 to "ON" and giving
a 230 V~ signal via an external timer or a
switch to IN1. The setpoint value changes -3
°C during winter operation and +3 °C during
summer operation.
External on/off
By setting DIP-3 to "OFF" and connecting
a 230 V~ signal to IN1, the fan convector
switches off.
Accessories
With PCR2 only one fan convector can be
controlled. If more than one fan convector
is to be controlled by the same control unit,
external regulation PCER2 is used. Each unit
must be supplied with a slave unit PCAS.
(E.g.: 2 x PCW, 2 x PCAS and 1 x PCER2)
Limit thermostat PCT
Secure the limit thermostat between the fins
on the water coil.
Winter operation
During winter operation the fan only starts
if the water temperature is greater than 38
°C and switches off if the temperature of the
water falls below 34 °C.
Summer operation
During summer operation the fan switches
off if the water temperature is greater than 24
°C and restarts when the temperature of the
water falls below 21 °C.
