− The limiting factors of the return ow sensor RüF1/RüF2 (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
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.
16.2.14 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owtemperatureandthesecondaryreturnow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(inuencefactor)determineshowstronglythecontrollerrespondswhenthe
temperature deviates from the set point of the differential temperature control.
