Table 10 Basic settings of heating circuits
Actuator runtime 5...120...600 s Setting the runtime of the available mixing
valves
Generally, servomotors have a runtime of
120 s.
If the mixing valve constantly oscillates, the
control characteristics can be slowed down by
reducing the operating time of the mixing valve.
Boiler temperature increase 0...5...20 K The flow temperature for the heating circuit is
obtained by adding the increase in boiler
temperature to the calculated/required flow
temperature.
If a heating circuit is controlled with a mixing
valve, a higher set value should be set for the heat
source than the normal set value for the heating
circuit.
DHW priority No/Yes The pumps of all heating circuits are switched
off during the water heating phase.
In heating circuits with mixer, the mixing valve is
moved in the “close” direction (colder).
Pump blocking protection Off/On Setting that determines whether or not a pump/
mixer is to be regularly switched on for short
periods to prevent it from seizing up during
extended downtimes.
Overrun time 0...2...60 min Setting that determines how many minutes a
pump should remain switched on once the
switch-on condition no longer exists.
Third party WF control
settings
None Switching the operating mode of the heating
circuit via an external contact (connecting
terminal WF) at the FM-MM and FM-MW module
