5.2 Control modes for the heating control unit
The heating control unit can operate in three control modes. Your
heating contractor will select and set up one of these options
according to your requirements:
– Room temperature control: in this case, the programming unit
must be installed in a room that is representative for the house.
The programming unit measures the temperature in this
"reference room". The flow temperature depends on the set
and actual room temperature. This means that outside
temperature influences in the reference room (e.g. an open
window, sunlight or heat from a fireplace) will affect the rest of
the house.
Adjust the room temperature of the house or the reference
room on the programming unit. To raise or lower the
temperature in other rooms, adjust the thermostatic radiator
valves.
