1.1 Remove the old thermostat
nCut the power source to your heating or air conditioning system.
oRemove the cover of the old thermostat.
CAUTION: If, upon removing the wall plate, you see that it is mounted on
a junction box (similar to the junction box located behind an electrical
switch or outlet), this may indicate that it is a 120-V / 240-V system. For
more security, consult a qualified electrician to check the installation.
1.2 Install the new thermostat
For a new installation, choose a location 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:
• air drafts (top of a staircase, air outlet,...)
• dead air spots (behind a door,...)
• direct sunlight
• concealed chimneys or stove pipes.
1.3 Install and connect the thermostat
nLoosen the captive screw holding the faceplate to the mounting
plate.
oPull the lower part to separate the faceplate from the mounting plate.
pFix the mounting plate onto the wall using the supplied screws.
1.4 Identify the wires
nIf 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
identifyingthe letters close to each screwor terminal on which a wire
is connected. These terminals may be located on either side of the
plate.
oDisconnect and identify each wire*.
pYou may need to tape the wires to the wall to keep them from falling
back into it. If the wall opening is bigger 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 mounting plate.
1.5 Connect the labelled wires to the thermostat
nConnect the system wires to the thermostat terminals according to
one of the wiring diagrams in section 1.6.
oMake sure to return the remaining wire length into the wall.
pIf you own a CT240 telephone controller, refer to section 6.1 for
connection.

1.7 Thermostat configuration
Configure the thermostat using the DIP
switches on the back side of the
faceplate.
1.7.1 24 hr. or 12 hr. Display
The TH141 offers a 12 hr. or 24 hr. mode display. Default
configuration of the display is in the 24 hr. mode. If you
prefer a 12 hr. display, push switch #3 up.
1.7.2 Temperature in °C or °F
Default configuration of the TH141 is in °C. If you wish to
change the temperature to °F, push switch #4 up. If you
change from °F to °C (or vice versa), you will need to
reprogram your comfort and economy settings.
1.7.3 Regulation Modes
You have a choice between two regulation modes:
• Proportional adaptive mode
• Conventional mode with anticipation
1. Proportional adaptive mode
If you want the proportional adaptive mode, push switch #5 up.
This mode analyses previous cycles to define the next duty
cycle. This operating mode guarantees optimal regulation based
on the capacity of your system. To avoid cycles that are too short
for the heating or air-conditioning units, minimum On and Off
duration is limited to 10% of the period (1.5 minutes for a 15
minute cycle).
Ideal for:
• Radiant or convection electrical heating system
• Circulator control in a hot water system
• Electrical hot air furnace
• Hot air, gas or fuel conventional furnace
• Air-conditioning system
Not recommended for:
• Gas or fuel furnace or boiler with wall chimney, if they include a
combustion gas purging cycle exceeding 30 seconds. To verify this
point, check the duration of the delay between the heating command
sent by the thermostat and the moment when the burner actually
goes on.
• Multi-zone systems, where several thermostats command a single
heating or air-conditioning unit.
In the last two cases, the conventional mode is recommended.
Regulation Cycle Length
Set the length of the regulation cycles using switches #1 and #2. When
cycles are very short, the temperature variation in the room is very low
and the comfort level very high. However, very short cycles can generate
premature wear of your system. It is therefore important to adjust the
cycles to your type of installation. In general, the bigger your heating or
air-conditioning unit, the longer the cycles should be.
• 5-minute cycle: For specific applications only
• 10-minute cycle: Radiant or convection electric heating
• 15-minute cycle: Central heating and air-conditioning unit
• 20-minute cycle: Commercial unit
2.Conventional mode with anticipation
If you want the conventional mode with anticipation, push switch
#5 down. This mode maintains the temperature within the
programmed span. This mode is compatible with all heating or
air-conditioning systems.
Programmable Span
Use switches #1 and #2 to select the appropriate temperature span.
* 240 volt heating with relay (baseboard, convector, radiant ceiling, etc.)
1.7.4 Heating Fan Control
This function determines whether the heating system
fan is operated by the thermostat or by the plenum's
temperature of the heating unit. In general, the fan is
operated by the heating unit. However, if the fan does
not turn on and the thermostat requires heating for
more than one minute, push switch #6 up.
1.8 Battery installation
When you first install the batteries in the TH141, the unit
runs a sequence of tests and a complete reset to zero,
which last approximately 5 seconds. The screen should
display the time and the day, as well as the current
temperature as follows:
It is normal for the displayed temperature to be higher
than the room temperature if your are holding the TH141
in your hands, It will return to normal about one hour after
installation on the wall. Mount the thermostat on the wall
plate and screw it in place.
Even if the thermostat indicates that the batteries are
still good, it is recommended to replace them once a
year, at the beginning of the cold season.
I
You may program the thermostat while holding it in your hands or when it
is mounted on the wall.
2.1 Programming the time and day
nSet the time using the Hour and Minute buttons.
oSet the day using the Day button.
2.2 Programming the comfort, economy and vacation settings
The Comfort , Economy and Vacation settings respectively
represent the temperatures that you wish to have during the day , at
night or while you are away at work , or while you are away for an
extended period . Since your thermostat controls both heating and air-
conditioning, and since the economy settings are the opposite in both
cases (reduction for heating temperature, increase for air-conditioning),
you must program the settings for heating and then for air-conditioning.

Use the Heat/Cool button to select one of the following modes:
Heating: Controls the heating unit.
Air-conditioning: Controls the air-conditioning unit.
Mixed: The TH141 analyzes the temperature pattern and
automatically alternates between heating mode and
air-conditioning mode.
To avoid needless switching, the automatic mode change will take at
least 2 minutes if it is required by a manual setting change and at least 15
minutes if it is due to a quick temperature change.
Furthermore, to protect your heating and air-conditioning system, it is
impossible to shut down and restart the system within a period equal to
10% of the cycle.
Use the Fan On/Auto button to force continuous air circulation (
appears) or to synchronize the fan with the heating or air-conditioning
demand ( disappears).
Please note that if you set the TH141 in Vacation mode using the
telephone controller or a house automation system, the continuous air
circulation will be automatically deactivated during your absence.
The TH141 incorporates a telephone controller interface which allows
you to switch from the normal operating mode to the Vacation setting
( ), and vice versa, using the telephone keypad (stationary or portable).
You can, for example, heat your country house from your office on Friday,
or your house from the airport or from your car on your way back from
vacation.
6.1 Connection to the CT240
The TH141 is designed to connect directly to
the CT240 telephone controller. This
combination allows the activation and
deactivation of the Vacation mode from the
