The thermostat must be mounted to a
connection box, at around 1.5 m (5 feet)
above the floor level, on a section of the wall
exempt from pipes or air ducts.
Do not install the thermostat in a location
where temperature measurements could be
altered. For example:
- close to a window, on an external wall, or
close to a door leading outside;
- exposed directly to the light or heat of the
sun, a lamp, a fireplace or any other heat
source;
- close or in front of an air outlet;
- close to concealed ducts or a chimney; and
- in a location with poor air flow (e.g. behind
a door), or with frequent air draft conditions
(e.g. head of stairs).
Seal the wall openings in order to minimize
the drafts which can alter temperature
measurements. Read the user’s guide of the
thermostat carefully and refer to the following
illustrations to connect the thermostat.
A humidifier and an electronic filter can be
controlled directly from the furnace. There
is a terminal block for this purpose in the
furnace as shown here in the diagram.
The terminal block is connected to an
internal relay that activates the auxiliary
devices when the blower of the furnace is
in operation.
