Operating instructions RC20 room controller • Issue 08/2006
– Outside temperature control (weather conditions):
The outside temperature is measured by a temperature
sensor. The level of the flow temperature is calculated
exclusively from the outside temperature using the set
heating curve.
The room temperature for the entire house can be set in the
programming unit (this causes the heating curve to move up or
down). The thermostatic radiator valves must be adjusted in
each room to a setting that will produce the required room
temperature.
– Outside temperature control influenced by the room
temperature: with this type of control, the flow temperature
depends primarily on the outside temperature, but it is also
determined by the room temperature within limits set by your
heating contractor.
USER NOTE
If the RC20 has been installed as the only programming unit,
room temperature control is always used.
If the RC20 has been installed as a remote control unit for a
heating circuit, the type of control that has been set for the higher
level programming unit (RC30/RC35) applies.
