6.1 Control options
6.1.1 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 tem-
perature set in the user level, see [ch.5.4.2].
Room frost protection and setting optimisation are not active.
6.1.2 Weather compensated control
The flow temperature is controlled depending on the external temperature.
An external sensor is required for weather compensated control.
Mount the external sensor to the north side or the north-west side of the build-
ing, half way up (min 2.5 m).
Avoid direct solar radiation and heat up by external heat sources at the external
sensor.
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 determines how much the
change in external temperature affects the flow setpoint temperature and adjusts
the heating curve to the building.
The heating curve can be moved vertically using the parallel movement.
Room temperature too coldRoom temperature too warm
Decrease room setpoint temperature
– or –
decrease parallel movement.

6.1.3 Room temperature dependent control
The flow temperature is controlled depending on the room temperature.
A room device or room sensor are required for room temperature dependent con-
trol.
Avoid direct solar radiation and heat up by external heat sources at the room
sensor.
The current flow temperature setpoint is calculated from:
room setpoint temperature,
current room temperature,
room sensor influence.
The room setpoint temperature can be set in the user level [ch.5.4.2].
The room sensor influence can be set in the Engineer level.
6.1.4 Weather compensated/Room control
The flow temperature of the heating circuit is controlled depending on the external
temperature and the room temperature.
An external sensor and room device or room sensor are required for weather compensated control and room temperature dependent control.
Mount the external sensor to the north side or the north-west side of the build-
ing, half way up (min 2.5 m).
Avoid direct solar radiation and heat up by external heat sources at the external
sensor and the room sensor.
