One (1) floor sensor
•
One (1) wall plate
Turn off power to the heating system at the main power panel to
avoid electrical shock. Installation should be carried out by an
electrician.
All work must conform to the applicable country standards for
electrical installations and wiring.
This thermostat should be connected on a circuit equipped with
a fuse or a circuit breaker. It must be installed on a certified
electrical box equipped with non-metallic cable strain relief
adapters. Use separate adapters for the high-voltage wires and
for the sensor cable.
For a new installation, choose a location about 1.5 m above the
floor.
For electric baseboards, convectors and fan-forced heaters, the
thermostat must be installed facing the heating system and on
an inside wall.
Avoid locations where there are air drafts (top of staircase, air
outlet), dead air spots (behind a door), direct sunlight or
concealed chimneys or stove pipes.
NOTE:
The terminals are designed to handle a cross-section of wire
measuring 0.33 to 3.1 mm
2
.
Loosen the captive screw underneath the base and remove the
faceplate from the base.
Before making the connections, make sure
that the base covers the electrical box
entirely. If not, install a wall plate at the
back of the base.

WARNING:
Ensure that the wires are tightly secured to the terminals.
Apply a minimum torque of 0.5 Nm (4.4 Lb/in) when tightening the
screws.
Note 1
If a contactor is used between the thermostat and the load,
install a snubber at the contactor’s coil terminal to ensure
the proper operation of the thermostat.
Note 2
This connection is required on some models only.
Note 3
The sensor cable must pass outside the electrical box and
travel inside the wall to the floor. For the proper operation of
the thermostat, the floor sensor must be centered between
two heater wires having a maximum temperature of 80 °C
(176 °F). The floor sensor wire must not cross any heater
wire or be placed close to it.
Push wires into the electrical box and
secure the base to the electrical box
anchorage. The head of the screw
must be less than 2 mm thick.
Return the faceplate
to the base
.
Return power to the heating system.
NOTE
: Keep the thermostat's air vents clean and unobstructed at all
times.
