Requirements
Before starting to install the system, ensure that the following
requirements are satisfied:
3.2.1
Suitable reference room
To ensure the heating control unit works properly, the RC20
room controller must be installed in a suitable reference room
(see User Manual).
Alternative heat sources (sunlight or other heat sources, such as
an open fire) in the reference room affect the control function of the
RC20. If there are alternative heat sources in the reference room,
rooms without alternative heat sources may be too cold.
USER NOTE
With a room temperature control system there is no need for
thermostatic valves on the radiators in the reference room. If there
are thermostatic radiator valves in the reference room they must
be kept fully open at all times.
