Functions of the DHW circuit
set point has reached 5 °C at the minimum. How strongly the controller responds is deter-
mined by the 'Influence factor KP'.
When 'Activate priority in the event of a system deviation' is set to 0, the priority operation is
started regardless of the time and temperature in the system. The control valve of the corre-
sponding heating circuit is closed.

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 SF1. If system deviations still occur after the time set
in 'Activate priority in the event of a system deviation' has elapsed, the selected heating cir-
cuit with the control valve is set to reduced operation.
When 'Activate priority in the event of a system deviation' is set to 0, the priority operation is
started regardless of the time and temperature in the system. of all heating circuits.
