7.5Condensate accumulation control

Activate the Condensate accumulation control 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.

In systems Anl 6 and 9, the limitation applies to all control valves; in all other systems, it applies to the control valve with the highest flow temperature set point.

In systems with DHW heating on the primary side (Anl 7 and 8), the Condensate accumulation control function must configured separately under Co4.

Note!

The condensate accumulation control function can only be activated when no on/off control has been configured, i.e. Co5 -> Fb14 = ON.

7.6Compensating for time delays

The controller regulates the control circuit with the highest flow set point with the secondary flow sensor. If the sensor is placed on the secondary side directly downstream of the heat exchanger and the setting Co5 -> Fb06 = ON configured, any time delays due to changes in temperature at a distant flow sensor do not occur anymore. This measure used with a condensate accumula- tion control means that the control can intervene before the control valve releases unproportionally too much heat exchanger area.
