Two-point operation
Two-point operation can be used as a radio test in order to test the radio connection between the base station and the
room control unit.
The radio test shows which heating zones of the base station the room control unit is coupled to.
ü This radio test must always be carried through at the planned installation location of the room control unit.
ü The base station must not be in pairing mode or within the 10-minute first-open function.
1. Set the temperature setpoint by turning the push-turn control clockwise to increase the setpoint or counterclockwise to
decrease the setpoint.
ð All heating zones assigned to the room control unit are controlled in a two-point mode for 30 minutes.
ð Changing the temperature setpoint on the room control unit turns the coupled heating zone on or off at the base sta-
tion in order to adjust the actual value to the new setpoint.
ð Load compensation is deactivated for all heating zones assigned to the room control unit.
If there is no activation, the reception is disturbed due to unfavorable conditions. Taking into account the installation condi-
tions of the room control unit, change the installation position until you have a reception signal.
