1. INSTALLATION
1.1 REMOVE THE OLD THERMOSTAT
1 - Cut the power source to your heating or air conditioning system.
2 - Remove the cover of the old thermostat.
Caution: If, upon removing the wall plate, you see that it is mounted on ajunction
box (similar
to the junction box located behind an electrical switch or outlet), this may
indicate that it is a120 V/240 Vsystem. For more security, consult aqualified
electrician
to check the installation.
1.2 INSTALL THE NEW THERMOSTAT
For anew installation, choose alocation about 1.5 meters (5 feet) above the floor,
with
good air circulation. The thermostat must be installed on an inside wall.
Avoid locations where there are:
a) air drafts (top of astaircase, air outlet, ... )
b)
dead air spots (behind adoor, ... )
c) direct sunlight
d) concealed chimneys or stove pipes.

1.3 INSTALL AND CONNECT THE THERMOSTAT
1. Remove the screw holding the thermostat mounting plate.
2. Lift the lower part to separate the plate from the thermostat.
3. Mount the plate on the wall using the screws supplied.

1.4 IDENTIFY THE WIRES
1. If the wall plate of your old thermostat has more than two wires coming out of the
wall, you will need to label the wires. Start by identifying the letters close to each
screw or terminal
on which awire is connected. These terminals may be located
on either side of the plate.
2. Disconnect and identify each wire *.
3. You may need to tape the wires to the wall to keep them from falling back into it.
If the wall cavity is larger than necessary, fill it with insulating wool in order to
prevent the infiltration of
warm or cold air behind the thermostat.
*If your installation is recent, the colour of the wires should match the identification on the
mountingplate.

1.5 CONNECT THE LABELLED WIRES TO THE THERMOSTAT
1. Connect the system wires to the thermostat terminals according to the wiring
diagram shown
in section 1.6.
2. Make sure that the wires are pushed well back into the wall.
3. If you own a CT240 telephone controller, refer to section 6.1 for connection.
1.6 WIRING DIAGRAMS
The TH141 thermostat is compatible with most heating and air conditioning systems.
Multi-level heating
and air conditioning systems, Milivolt control heating systems, heat
pumps and baseboard heating units are not compatible with this thermostat. Baseboard
units
can be connected using a 24 V relay.
1.6.1 2-WIRE HEATING SYSTEM
1. Connect the heating relay to terminal W.
2. Connect the 24 Vtransformer to terminal Rh.
In this case, the order of connection is unimportant.
