Installation should be carried out by an electrician.
• For a new installation, choose a location about 5 ft. (1.5 m) above
the floor.
• The thermostat must be installed facing the heating system and on
an inside wall.

let), dead air spots (behind a door), direct sunlight or concealed
chimneys or stove pipes.

if necessary, connect the remote input (see section 1.3).
Once wiring is complete, re-install the wire cover.

ure your thermostat (see section 1.4) according to your applica-
