Overtemp prot pump circuit
In the case of heating plant with pump heating circuits, the flow temperature of the
heating circuit can be higher than the flow temperature called for by the heating curve,
due to higher requests from other heat consumers (mixing heating circuit, DHW
charging, external heat demand), or a parameterized minimum heat pump temperature.
As a result of this too high flow temperature, the pump heating circuit would assume
excessive temperatures.
Function “Overtemperature protection for pump heating circuits” ensures that the
energy supply for pump heating circuits corresponds to the demand from the heating
curve by activating / deactivating the pump.

For mixing, the actual value of the boiler flow temperature must be higher than the
required setpoint of the mixing valve flow temperature since otherwise that temperature
cannot be controlled. The controller generates the boiler temperature setpoint based on
the increase set here and the current flow temperature setpoint.
Selection of the type of actuator determines the way the control action impacts the type
of mixing valve actuator used.
For the 2-position actuator, the 2-position switching differential must also be adapted.
This is not required when using 3-position actuators.
