Aube Technologies TH147 Installation And User Manual
TH147 and TH148LE
400-147-010-C 27/11/06 1/4
The TH147 and TH148LE 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 or TH148LE thermostat cannot be used.
o
Identify 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.
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.
