The function is used primarily in connection with heating systems with
only
little spare
capacity (e.g. low-energy houses). In such cases, the heating up time at low outside
temperatures would be too long. When the Reduced setpoint is raised, the rooms are
prevented from cooling down excessively, thus shortening the heating up time when
changing to the nominal setpoint.

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