The comfort temperature boost is added to the set day correction. In this manner it is possible to carry out quick heating and/or raise the
temperature of living spaces at a certain time each day.
Min. Flow
The minimum flow temperature is the lower limit of the heating curve, and by this, the reference flow temperature of the heating circuit. In
addition to that, the minimal flow temperature is the reference flow temperature for the frost protection function.
Max. Flow
This value is the upper limit of the reference flow temperature of the heating circuit If however, the temperature of the heating circuit
exceeds the set value, the heat circuit shuts down until the temperature falls below this value. After 55 seconds, rinse for 5 seconds.
The customer must provide an additional limiting thermostat which is connected to the pumps in series (eg underfloor heat-
ing) for safety.
Reference/Actual -
Switch on hysteresis for additional heating
This setting determines the allowed undershoot of the heating circuit temperature below the calculated reference fl ow temperature. If
the heating circuit flow temperature and the storage temperature drop below the reference flow temperature by this value, the additional
heating will start the additional heat source after a 1 minute delay.
Heat request is started when the flow temperature is continuously below reference temperature for 1 minute.
Reference/Actual +
This value determines the acceptable underflow of the heating circuit temperature beyond the calculated reference flow temperature at
the buffer sensor or flow sensor. If the temperature at the buffer sensor exceeds the reference flow temperature by the value set here, the
heating request is deactivated.
The setting value reference/actual + appears only in the menu if a sensor has been set under buffer sensor.
Variant
Only appears, if the heating circuit is an unmixed heating circuit (no mixer 1).
The condition for switching off the heating circuit pump is set. In the mode flow (FL), the pump is shut down, if the reference temperature
is exceeded. In the summer/winter mode (SW), it is shut down in the winter mode at Tmax, in the summer mode the heating circuit pump
is shut down in general.
The sensor should be placed in the return line in the VL mode.
Heating circuit off
If you use a room controller, the heating circuit can also be switched off on the base of the room controller in addition to the switch-off
according to outside temperature.
Summer: Heating circuit turns off when the summer/winter time changeover (outside temperature) is exceeded.
Summer + Room: Heating circuit is turned off as soon as the summer/winter time changeover (outside temperature) or the room set-
point temperatures are exceeded.
Room hysteresis
Only appears, if "Switch off heating circuit" has been set to "Summer+Room". If the reference room temperature + the hysteresis set here
are exceeded, the heating circuit is switched off.
In cooling mode, reactivation when the room temperature is exceeded.
Buffer sensor
Input of heating circuit buffer sensor.
In this menu, the sensor is set, which is used as a reference sensor for the heating circuit request. Switching on and off conditions for a
heating circuit request See " Reference/Actual - " on page 34 / See " Reference/Actual + " on page 34.
The request only works if an energy source (burner, compressor, solid chamber) is activated as an additional function and if
this source is set for the heating circuit request
(see also
