7.3.1.5Heating circuit temperature limit

NOTE This function is not active if the heating circuit control is used as constant control (CC).

Function This function limits the flow temperature of a heating circuit. The minimum and maximum temperatures set in the relevant parameters of a heating circuit do not exceed or fall below the setpoints.

Minimum temperature limitation is not active:

•in case of switch-off in standby mode above the frost protection limit

•in case of switch-off in reduced automatic mode with the activated ECO function above the frost protection limit

•in case of switch-off in continuously reduced mode with activated ECO function

•in case of automatic summer switch-off

Application • Floor minimum limit

•Ventilation pre-adjustment (warm air curtain)

•Convector heating

ATTENTION

To protect the floor heating systems against accidental overheating (malfunction - manual mode) a controller- independent maximum temperature limit must be provided. For this purpose, we recommend a strap-on thermostat, the switching contact of which is looped through the control phase of the respective heating circuit pump. The thermostat is to be set to the maximum permissible system temperature.
