9. HEATING
Heating circuit switched off means that the heating circuit pump is switched off and the mixer
closed. The flow temperature is boosted to maximum for rapid heat-up when the remote control
is set to rapid heat-up.
If the outdoor temperature sensor is defective, an error message will be indicated. For the dura-
tion of this condition, the maximum flow temperature -5 K is assumed as the set flow tempera-
ture in the Curve and Linear mode.
By means of the adjustment channels TFlowmax and TFlowmin the maximum and minimum
values for the set flow temperature can be defined.
The Constant mode aims to keep the set flow temperature at a constant value which can be
adjusted by means of the parameter TFlowset.
Set flow temperature = TFlowset + remote control + day correction or night correction
NOTE:
The controller uses an averaged outdoor temperature.
If the Curve mode is selected, the controller calculates a set flow temperature by means of
the outdoor temperature and the heating curve selected. In both cases, the dial setting of the
remote control and the controller day correction or night correction will be added.
Set flow temperature = heating curve temperature + remote control + day correction or night
correction.

Outdoor temperature in °C
In the Linear mode the flow temperature curve will be calculated depending on the out-
door temperature by 2 points. At a temperature of TOutdoor 1 the set flow temperature is
TFlow 1. At a temperature of TOutdoor 2 the set flow temperature is TFlow 2. The controller
automatically calculates the characteristic curve resulting from these values.
In the Room influence mode, the weather-compensated set flow temperature will be expand-
ed by a demand-based room control. The parameter Room factor can be used for determining
the intensity of the room influence.
The controller will calculate the set flow temperature using the heating system Curve plus the
room influence: Set flow temperature = set temperature + remote control + day correction or
night correction + room influence.
In order to calculate the deviation of the room temperature from the adjusted set value, at least
one sensor-type room thermostat is required. The adjustments can be made in the Room
therm. submenu.
In the Room mode, the controller will calculate the set flow temperature by means of the room
temperature, the outdoor temperature will not be taken into account.
Day/Night correction and Timer will not be indicated.
The start value of the set flow temperature can be influenced by the parameter TStart.
In order to calculate the deviation of the room temperature from the adjusted set value, at least
one sensor-type room thermostat is required (see page 154). The adjustments can be made
with the Room therm. (1 ... 5) parameter. For this purpose, select Sensor in the Type adjust-
ment channel.
The adjustments of all activated room thermostats will be taken into account. The controller will
calculate the average value of the deviations measured and correct the set flow temperature
correspondingly.
