Heating
In this menu, all adjustments for the heating circuit can be made.
Additionally, the screed drying function can be activated and adjusted.
Heating circuit
The controller has one heating circuit. The following heating circuit variants are
possible:
• 1 mixed weather-compensated heating circuit
• 1 mixed constant heating circuit
If the measured flow temperature deviates from the set flow temperature, the valve
will be controlled in order to adjust the flow temperature correspondingly.
The control runtime can be adjusted with the parameter Interval.
The heating system Constant aims to keep the set flow temperature to a constant
value which can be adjusted by means of the parameter Set temperature.
If the heating system Curve is selected, the controller calculates a set flow temper-
ature by means of the outdoor temperature and the selected Heating curve. In
both cases, the dial setting of the remote control and the controller day correction
or night correction are added.
Heating system Constant:
Set flow temperature = set temperature + remote control + day correction or
night correction
Heating system Curve:
Set flow temperature = heating curve tempe remote c day correc-
tion or night correction
The calculated set flow temperature is limited by the adjusted values of the param-
eters Maximum flow temperature and Minimum flow temperature.
Flow maximum temperature
≥
set flow temperature
≥
flow minimum temperature
The parameter Pump off is used for switching off the heating circuit pump, if the
adjusted value of the maximum flow temperature is exceeded by 5 K.
If the outdoor temperature sensor is defective, an error message will be indicated.
For the duration of this condition, 0 °C is assumed as the outdoor temperature.
