duced each minute until the ow temperature set point has reached 5°C at the minimum.
How strongly the controller responds is determined by the 'KP' (inuence factor).
When 'Start' is set to 0, the priority operation is started regardless of the time and tempera-
ture in the system. The control valve of the corresponding heating circuit is closed.
The reverse control can be activated for each heating circuit separately in system Anl 4.5.

7.9.2 Set-back operation
In all systems with DHW heating and at least one heating circuit with a control valve, DHW
heating can be given priority by applying set-back operation. With the setting CO4 > F09 -
1, the temperature is monitored at sensor VFx in the DHW circuit.
In systems without sensorVFx in the DHW circuit (e.g. Anl 4.5, 11.0), the temperature is
monitored directly at storage tank sensor1. If system deviations still occur after the time set in
'Start' has elapsed, the selected heating circuit with the control valve is set to reduced opera-
tion.
When 'Start' is set to 0, the priority operation is started in all heating circuits regardless of
the time and temperature in the system.
The reverse control can be activated for each heating circuit separately in system Anl 4.5.
