The housing of the TRM2... room thermostats is made of plastic. A captive screw,
invisible from the front, allows easy fitting of the cover.
Cable is introduced through an opening in the rear plate, or through the top.
Mounting instructions are enclosed with the room thermostat (Ref. 35200).
The sensor should be mounted at a height of approximately 1.5 m above floor level and
at least 0.5 m from the corner of the room. Do not install the sensor in a position where it
will be exposed to direct sunlight. Avoid locations where there may be undue influence
from heat or moisture, such as near doors, windows, chimneys etc., and locations with
inadequate air circulation (in recesses, behind furniture or curtains etc.).
