6.1 Control modes for heating control
The heating control can operate in three control modes: Upon request, your heating contractor will
select and set up one of these options:
• Outside temperature control (weather-compensated control): the outside temperature is
recorded by means of a temperature sensor. The flow temperature is calculated solely on the
basis of the outside temperature in accordance with the set heating curve.
You can set the room temperature for the entire home at the programming unit (which will shift
the heating curve up or down). Adjust the thermostatic radiator valves in every room to achieve
the required room temperature.
• Room temperature control: in this case, the programming unit must be mounted in a room which
is representative of your home. The programming unit records the room temperature in this
“reference room”. Control of the flow temperature is determined by the set room temperature and
the recorded room temperature. Consequently external temperature influences in the reference
room (e.g. open windows, sunlight or heat from a fireplace) will affect your entire home.
Set the room temperature of your home or reference room at the programming unit. You can
achieve higher or lower temperatures in the other rooms by adjusting the thermostatic radiator
valves.
• Weather-compensated control with room temperature hook-up: with this control mode the flow
temperature is primarily determined by the outside temperature, but it is also partly determined
by the room temperature according to the range of adjustments which can be made by your
heating contractor.
The following applies to room temperature control and for weather-compensated
control with room temperature hook-up:
the thermostatic radiator valves in the “reference room” (the room where the
programming unit is located) must be fully opened. Control of the flow temperature
is determined by the room temperature recorded there. It must not be limited by closed
thermostatic valves.
