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.

2

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.

1.7 THERMOSTAT CONFIGURATION
Before mounting the thermostat on the wall, configure it
using the switch bank on the back side of the unit.
a) 24 hrs. or 12 hrs. Display o
H J12 h
3124 h
The TH141 offers a 12 hrs. or 24 hrs. mode display. Default configura-
tion of the display is in the 24 hrs. mode. If you prefer a 12 hrs. display,
push
#3 switch up.
6

b) Temperature in °C or of
Default configuration of the TH141 is in °e. If you wish to change the
temperature to
of, push #4 switch up. Please note that if you changefrom
of to °e, your comfort and economy settings will need to be
reconfigured as well.
e) Regulation Modes
You have achoice between two regulation modes:
a J'~I.A •Proportional adaptive
~ lOEAOBANO •Conventional with anticipation
1. Proportional adaptive mode
If you want the proportional adaptive mode, push #5 switch up.
HThis mode analyses previous cycles in order to define the length of the up
5coming 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% ofthe
period (1.5 minutes for a15 minute cycle). 7

Ideal for:
•Radiant or convection electrical heating system
•Circulator control
in ahot 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 acombustion 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 asingle heating or air-
conditioning unit.
In the last two cases, the conventional mode is recommended.

Regulation Cycles
In proportional adaptive mode, the TH141 adapts the regulation cycles to your sys-
tem capacity. 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 pre-
mature 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. The TH141 offers the possibility of programming regulation periods of 5,
10, 15 or 20 minutes using switches 1and 2 at the back of the unit.
We recommend the following options:
• 5 minute cycle Not recommended for central units

2. Conventional mode with anticipation
H If you want the conventional mode with anticipation, push #5 switch down.
5
This mode commands the system's On and Off cycles when the temperature read
by the thermostat reaches pre-set levels. This mode is compatible with all heating or
air-conditioning systems.
Programmable Span
When the thermostat is in conventional mode with anticipation, it is possible to pro-
gram a
span, that is temperature variations between ON and OFF orders of your sys-
tem. These variations are programmable between 0.3 and 0.6 °C (0.5 and 1 .1 OF) and
they correspond to the following positions of switches #1 and #2:
0.3 aCIO.5 of
0.4 aCID.? of

d) Heating Fan Control
This function determines whether the heating system fan is opera-
aTH141 ted by the thermostat or by the plenum's temperature of the heating
!! -FAN unit. In general, the fan is operated by the heating unit. However, if
6Plenum the fan does not turn on and the thermostat requires heating for more
than one minute, push #6 switch up.

1.8 BATTERY INSTALLATION
When you first install the batteries in the TH'141, the unit runs asequence
of tests and acomplete 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 TH 141 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 good, it is recommended
to replace them once a year, at the beginning of the cold season.

2. ENTRY OF BASIC DATA
You mayprogram the thermostat while holding it in your hands or once it is mounted
on the wall.
2.1 PROGRAMMING THE TIME AND DAY
1. Set the time using the Hour and Minute buttons.
2. Set the date using the Day button.
2.2 PROGRAMMING THE COMFORT, ECONOMIC AND VACATION SETTINGS
The Comfort ~'9:- ,Economic «and Vacation 11II 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 11II .Since your
thermostat controls both heating and air-conditioning, and since the economic
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.
