fied installer.
2.1 Removing the Old Thermostat
IN ORDER TO AVOID ANY RISK OF ELECTRIC SHOCK, CUT
POWER TO THE HEATING/COOLING SYSTEM.

Remove 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-P thermostat cannot be used.

Identify and label each wire (with the corresponding letter on the
wire terminal) and remove them from the terminals.

If necessary, strip the end of each wire
(maximum of 6 mm).

Wrap the wires around a pencil to prevent
them from falling into the wall.

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
1.
For a new installation, choose a location approximately 1.5 m (5

(top of staircase, air outlet, etc), dead air spots (behind doors),
direct sunlight or areas near concealed pipes or chimneys.

Remove the thermostat faceplate.

Loosen the locking screw in order to separate the thermostat
from its baseplate (the screw cannot be completely removed).

Gently tilt the thermostat upwards.

Mark and bore the appropriate mounting holes (or use the
existing holes). Insert the plastic anchors.

Pass the wires through the opening of the baseplate and fix the
baseplate to the wall using the screws provided.
