oInstallation

Note: The installation must be performed by a qualified electrician.

2.1 Removing the Old Thermostat

IN ORDER TO AVOID ANY RISK OF ELECTRIC SHOCK, CUT POWER TO THE HEATING SYSTEM.

nRemove the old thermostat to access the wires.

oIdentify and label each wire (with the corresponding letter on the old ther- mostat terminals) and remove them from the terminals.

pIf necessary, strip the end of each wire (maximum of 6 mm).

qIf necessary, wrap the wires around a pencil to pre-

vent them from falling into the wall cavity.

r If the opening in the wall is too big, insulate it using a non-flammable material to avoid air draughts behind the thermostat.

2.2 Installing the Back Plate

Note: For a new installation, choose a location approximately 1.5 m (5 feet) above the floor and on an inside wall. Avoid draughty areas (top of staircase, air outlet, etc.) or dead air spots (behind doors). Do not install the thermostat on a wall concealing air ducts nor expose it to direct sunlight.

nLoosen the locking screw (the screw cannot be com- pletely removed).

o Detach the front module from the back plate by pulling the bottom part.

pIf necessary, bore the mounting holes

and insert anchors.

q Pass the wires through the opening of the back plate and fix the plate to the wall using the screws provided.

2.3 Connecting the Thermostat

The connection of the new thermostat should be similar to that of the old ther- mostat; however, it can vary depending on the installation.

2.5 Completing the Installation

nReinstall the front module onto the back plate and tighten the locking screw.

oPlace the system mode selector switch to OFF.

Note: Leave the switch to OFF until you have verified that the thermostat is properly configured (see section 3).

pApply power back to the system.

qEnsure that the thermostat is configured according to your system type (see section 3).
