• One (1) thermostat

• 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

n Loosen the captive screw underneath the base and remove the

faceplate from the base.

o 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.

p Connect the wires:

• Power: Terminals 1 & 5

• Load: Terminals 2 & 4 see note 1

• Pilot Wire: Terminal 3 see note 2

• Floor sensor: Terminals 6 & 7 (no polarity) see note 3

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.

r 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.

s Return the faceplate

to the base.

t Return power to the heating system.

NOTE: Keep the thermostat's air vents clean and unobstructed at all times.

This thermostat provides the following temperature control modes:

Display

Apply power to the thermostat at the main electrical panel. At power-up, the thermostat is in manual mode and displays the

actual (measured) temperature. The setpoint temperature is 28 °C (82 °F).

LO The actual temperature is below 0 °C (32 °F). HI The actual temperature is above 70 °C (158 °F). Er The thermostat built-in sensor is defective. Replace the
