Time program 4 / DHW
For DHW heating, time switch program 4 of the local controller is used. The set
switching times of that program are used to switch between the nominal DHW setpoint
and the reduced DHW setpoint. This way, the DHW is heated independently of the
heating circuits.
Example:
2.4 Pump H1/H2
pump H1
Line no. Operating line
H1 H2
2008 2033 H1/H2 DHW charging priority
Off ¦ On
When using this setting, the connected pump H1/H2 can be excluded from / included in
the effect of DHW charging priority.
In the case of a ventilation system, for example, it is thus possible to ensure a constant
supply of heat with no impact from DHW charging priority.
2.5 Primary controller / system pump
flow temperature setpoint limitations
Line no. Operating line
2110 Flow temp setpoint min
2111 Flow temp setpoint max
Using this limitation, a temperature range for the flow temperature setpoint can be
defined. If the requested flow temperature setpoint reaches the relevant limit and the
heat request increases or decreases, the flow temperature setpoint will be maintained
at the maximum or minimum limit.
