Installation guidelines

TURN OFF POWER TO THE HEATING SYSTEM AT THE MAIN POWER PANEL TO AVOID ELECTRICAL SHOCK.

• All cables and connections must comply with local electrical codes.

• This thermostat has tinned copper wires for line and load connections. Special CO/ALR solderless connectors must be used if these wires will be connected to aluminium conductors.

• Install the thermostat onto an electrical box.

• Install the thermostat about 1.5 m (5 feet) high, on an inside wall facing the heater.

• Avoid locations where there are air drafts (such as the top of a staircase or an air outlet), dead air spots (such as behind a door), or direct sunlight.

• Do not install the thermostat on a wall that conceals chimney or stove pipes.

• The thermostat wires are not polarized; either wire can be connected to the load or to the power supply.

Mounting the thermostat

Loosen the screw underneath the thermostat and separate the faceplate from the wallplate.

NOTE: The screw remains captive and cannot be completely removed.

Mount the wallplate to the electrical box using the provided screws. Insert the screws through the two left or the two right mounting holes of the wallplate.

Reinstall the faceplate onto the wallplate and tighten the screw underneath the thermostat.

NOTE: If there is a protective film or sticker on the thermostat’s screen, peel it off.

Apply power to the heating system. Verify the installation by checking that the heating system can be turned On by raising the setpoint using the Up button or turned Off by lowering the setpoint using the Down button.

WAR NI NG: Keep the thermostat's air vents clean and free from obstructions.
