Functions of the heating circuit
Cooling control without outdoor sensor
When the cooling control function is activated in a control circuit without outdoor sensor, only
the adjustment limits for the day and night set points at the rotary switch as well as the 'Base
point for return flow temperature' can be adjusted in PA1 and/or PA2.

The limiting factors of the
return flow sensor RüF1/RüF2 (
CO
1, 2 > F03) functions apply
during cooling control as well.
−
The request for a signal by downstream control circuits or externally (when a pre-control
circuit is used) is based on the maximum selection. Therefore, systems (e.g. system Anl 3.0)
or systems in which the demand is requested using a 0 to 10 V signal are not suitable for
transmitting the signal for required cooling. The 'Set point boost (pre-control circuit)' pa
-
rameter can only generate higher and not lower set points in the pre-control circuit.
