HC108 Heating limit For mixer and uncontrolled heating circuits a heating limit can be set in the user menu
above which the heating mode is blocked.
HC109 Room infl uence
Above this outside temperature, no further heating demand is generated by the
heating circuit. The heating limit is deactivated with the setting 0.
The room infl uence factor shows to what extent the control system reacts to the room
temperature.
HC110 Heating curve
If the room unit is assembled in a room affected by other heat sources (e.g. a tiled
stove) a smaller proportion should be selected. The temperature of the room in which
the room unit is assembled, also affects the heating of the other rooms.
Note: Parameter is only visible in the case of confi gured room unit.
Given the steepness of the characteristic heating curve, the relation of the outside
temperature to the required fl ow temperature is established.

The greater the steepness of the characteristic curve is set, the higher the fl ow
temperature for the heating depending on the outside temperature as well as on the
heating and cooling limits.
Parameter for the desired room temperature during Normal Cooling mode.
Parameter for the desired room temperature during ECO Cooling mode.
HC153 Cooling fl ow Parameter for the desired cooling circuit fl ow temperature.
HC154 Dew-point gap This shows the minimum temperature difference between the dew-point (room humidity
sensor) and the set fl ow temperature.
HC108 Cooling limit Below this outside temperature no further cooling demand is generated by the
cooling circuit.
