Parameter
Return flow temp. points 1 to 4
NOTICE
To ensure that the preset return flow temperature limit can be met, make sure that
– the heating characteristic is not adjusted to ascend too steeply,
– the speed of the circulation pumps is not set too high,
– the heating systems have been calibrated.

Condensate accumulation control

Activate the Limit deviation for OPEN signal function to start up condensate accumulation
plants, in particular to avoid problematic excess temperatures. 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 control valve to close remains unaffected.
Note: The condensate accumulation control function can only be activated when the control cir-
cuit concerned is controlled using a PI algorithm (three-step control).
