2.1 Removing the Old Thermostat

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

nRemove the old thermostat to access the wires.

Attention: If the old thermostat was mounted onto an electrical box, it might have been powered by 120/240 volts. In this case, the TH147 or TH148LE thermostat cannot be used.

oIdentify and label each wire (with the corresponding letter on the wire terminal) and remove it from its terminal.

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

q Wrap the wires around a pencil to prevent them from falling into the wall.

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

2.2 Installing the New Baseplate

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.), dead air spots (behind doors), direct sunlight or areas near concealed pipes or chim- neys.

nRemove the thermostat faceplate.

oLoosen the locking screw in order to separate the thermostat from its baseplate (the screw cannot be completely removed).

pGently tilt the thermostat upwards.

qMark and bore the appropriate mounting holes (or use the existing holes). Insert the plastic anchors.

rPass the wires through the opening of the baseplate and fix the baseplate to the wall using the screws provided.
