4 Control options
4.1 Constant flow temperature
No additional sensors or thermostats are required for this control.
The flow temperature from the heating circuit is controlled to the flow
setpoint temperature set in the user level,
see [ch. 3.6.3]
.
Room frost protection and setting optimisation are not active.
4.2 Weather compensated control
The flow temperature is controlled depending on the external tem-
perature.
An external sensor is required for weather compensated control.
The current flow temperature setpoint is calculated from:
external temperature,
Heating curve:
Gradient ,
Parallel movement ,
Room setpoint temperature.
A higher flow temperature is required to achieve the desired room
temperature, when external temperatures are lower. The gradient de-
termines how much the change in external temperature affects the
flow setpoint temperature and adjusts the heating curve to the build-
ing.
The heating curve can be moved vertically using the parallel move-
ment.
