− The limiting factors 'KP' of the return flow sensor (CO1, 2 > F03) functions apply during
cooling control as well.
− The request for a signal by downstream control circuits or externally (when a pre-control cir-
cuit 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 trans-
mitting the signal for required cooling. The 'Set point boost (pre-control circuit)' parameter
can only generate higher and not lower set points in the pre-control circuit.
6.13 Differential temperature control
In systems Anl 1.0 and 16.0, the differential temperature control causes the delivery rate of
pump UP1 to be adapted through the 0 to 10 V output depending on the difference between
the secondary flow temperature and the secondary return flow temperature. In system
Anl 1.0 the sensor input RüF2 is automatically activated for this purpose with the setting
CO1 > F23 - 1. In system Anl 16.0, the sensor inputs VF2 and RüF2 are automatically acti-
vated. The KP (influence factor) determines how strongly the controller responds when the
temperature deviates from the set point of the differential temperature control.
