4.3 Installation location
Only install the controller and the radio receiver
unit in dry rooms.
The controller should be fitted so as to ensure
problem-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.
Check the mounting locations prior to installing
the controller and radio receiver unit regarding
possible functional impairment of the radio signal
path due to electrical appliances or building
features. If interference in the signal path is likely
an alternative installation location must be found.
Inform the operator that all radiator valves in the
room where the VRT 392f is mounted must be
fully opened.
