TURN OFF POWER TO THE HEATING SYSTEM AT THE MAIN POWER

PANEL TO AVOID ELECTRICAL SHOCK.

• The installation must be performed by a qualified electrician and must

comply with electrical codes of your region.

• Do NOT install the thermostat in an area where it can be exposed to water or

rain.

• 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 section that conceals air ducts,

chimney pipes or stove pipes.

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

heater.

• Install the thermostat onto an electrical box.

• This thermostat has tinned copper wires for line and load connections.

Special CO/ALR solderless connectors must be used if the thermostat will

be connected to aluminium wires.

• The thermostat wires are not polarized; either wire can be connected to the

load or to the power supply.

• Keep the air vents at the top and bottom of the thermostat clean and free

from obstructions.

Installation guidelines

1) Loosen the screw and remove the faceplate of

the thermostat from its wallplate. (The screw

remains captive on the wallplate.)

2) Make the connections using solderless

connectors for copper wires. The thermostat

wires are non-polarized; this means either wire

can be connected to either terminal.

3) Install the wallplate to the electrical box.

4) Set the configuration switches on the back of

the thermostat’s faceplate (see page 6).

5) Install the faceplate of the thermostat back on

the wallplate and tighten the screw.

6) If there is a protective film or sticker on the

thermostat’s screen, peel it off.

7) Apply power to the thermostat. Verify the

installation by checking that the heater can be

turned On and Off by raising and lowering the

setpoint using the and buttons.
