Set-Back Operation; Forced Charging Of The Dhw Storage Tank - Samson TROVIS 5573 Mounting And Operating Instructions

Activate priority in case of deviation has elapsed, the set point of the heating circuit with the
control valve is gradually reduced each minute until the flow temperature set point has reached
5 °C at the minimum. How strongly the controller responds is determined by the KP correction
factor .
Functions
Priority through reverse control
Priority through set-back operation 0

6.8.2 Set-back operation

In all systems with DHW heating and at least one heating circuit with control valve, DHW heat-
ing can be given priority by applying set-back operation. With the setting CO4 -> F08 - 1, the
temperature at sensor VFx can be monitored in the DHW circuit. In systems without the sen-
sor VFx in the DHW circuit (e.g. Anl 4.5, Anl 11.0), the temperature directly at the storage sen-
sor SF1 is monitored. If system deviations still occur after the time for Activate priority in case of
deviation has elapsed, the heating circuit with control valve is set to reduced operation.

Forced charging of the DHW storage tank

To provide the full network performance for room heating when the time-of-use of the heating
circuits begins, any storage tanks are charged one hour before the time-of-use of the heating
circuits starts.
For the individual controller, this means that storage tank charging is activated when the water
temperature in the storage tank falls below the adjusted deactivation value of T = DHW temper-
ature + hysteresis .
The forced charging of the storage tank does not take place when the DHW circuit is not used at
the beginning of the time-of-use set for the heating circuit(s).
Note: This function is not available when a storage tank thermostat is used.
