Note!
If the VRC 430f is connected to additional
components, please observe all instructions in
relation to those components.
4.3 Installating
the
unit
Only install the controller and the radio receiver unit
in dry rooms.
The controller should be fitted so as to ensure prob-
lem-free measurement of the room temperature;
e.g. on a room wall of the main living room at a
height of approx. 1.5 m.
Before you install the controller and wireless out-
door sensor, check the intended locations for possi-
ble functional impairment of the radio signal path by
electrical devices or building components. If inter-
ference in the signal path is likely, an alternative in-
stallation location must be found.
If the switch-on room temp. is activated, advise the
user that, in the room where the controller is
mounted, all the radiator valves must be fully open.
See Section 4.5 for the mounting location of the wire-
less outdoor sensor.
