Parameters
Rücklauftemp. max
(max. return flow temperature)
Rücklaufbegrenzung
(mit P-Algorithmus)
(return flow limitation
with P algorithm)
Steigung, Rücklauf
(gradient, return flow)
Niveau, Rücklauf
(level, return flow)
Fußpunkt Rücklauftemperatur
(return flow temperature foot)
The return flow temperature can also be monitored by a thermostat. The input of the return flow
sensor is defined as the binary input:
– UE9 of the controller for RüF1 (heat exchanger WT1)
– UE8 of the controller for RüF2 (heat exchanger WT2)
– UE1 of the controller for RüF3 (heat exchanger WT3)
Note: To be able to keep to the defined return flow temperature limit, make sure that the hea-
ting characteristic is not selected too steep and the speed of the circulation pumps is not too
high.

Condensate accumulation control

To start up condensate accumulation plants, in particular to avoid problematic excess tempera-
ture, the condensate accumulation control can be activated by setting an attenuation intensity
(between 2 and 10 °C). The controller response to set point deviations which cause the primary
valve to open is attenuated. The controller response to set point deviations which cause the con-
trol valve to close remains unaffected.
