a position with good air circulation, at average room
temperature and on an inside wall 1.5 metres, above the floor

doors or windows, or in direct sunlight.
MOUNTING
The CM907-
thermostat can be mounted directly on the
TRV
wall surface or on an electrical wallbox.
WIRING
The CM907-
thermostat is designed for fixed wiring only
TRV
and must be installed in accordance with the latest l.E.E.
regulations. Ensure the wiring connection to the supply is via
a fuse rated at no more than 8 amps and a Class "A" switch
(having contact separation of at least 3 mm in all poles).
