TH147-P and TH148LE-P

400-147-000-D 18/4/06 1/5

The TH147-P and TH148LE-P programmable thermostats can be
used to control:
• a gas, fuel oil or electric furnace - 2 or 3 wires
• a central air conditioner - 2 or 3 wires
• a hot water system with or without pump - 2 wires
• a millivolt system - 2 wires
• a central heating and cooling system - 4 or 5 wires

Attention

: These thermostats are not compatible with heat pumps

or multi-stage systems.

Note

: The installation must be performed by an electrician or a qual-

ified installer.

2.1 Removing the Old Thermostat

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

n

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 or TH148LE-P thermostat cannot be used.

o

Identify and label each wire (with the corresponding letter on
the wire terminal) and remove them from the terminals.

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.

n

Remove the thermostat faceplate.

o

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

p

Gently tilt the thermostat upwards.

q

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

r

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