1.1 Guidelines
TURN OFF POWER TO THE HEATING SYSTEM AT THE MAIN
POWER PANEL TO AVOID ELECTRICAL SHOCK.
Installation should be carried out by an electrician.
• For a new installation, choose a location about 5 ft. (1.5 m)
above the floor.
• The thermostat must be installed facing the heating system and
on an inside wall.
• Avoid locations where there are air drafts (top of staircase, air
outlet), dead air spots (behind a door), direct sunlight or con-
cealed chimneys or stove pipes.
!Remove the screw (captive) holding the base to the control
module.
"Lift the lower part of the module to remove it from the base.
#Remove the screw (captive) holding the wire cover and remove
the wire cover.
$Pull wires through the base hole and secure the base to the
wall (or onto an electrical box for line voltage wiring) using the
enclosed wall anchors and screws.
%Wire the base to the heating system (see section 1.2) and con-
nect the remote input, if necessary (see section 1.3).
&Once wiring is complete, re-install the wire cover.
'Use the switches located at the back of the control module to
configure your thermostat (see section 1.4) according to your
application.
(Install the batteries (see section 1.5).
)Mount the control module on the base and secure using the
screw.
1.2 Thermostat Wiring
LOW VOLTAGE < 30 V: no polarity
LINE VOLTAGE 120 to 240 VAC
Must be installed onto a certified electrical box.
For a 2-wire connection: no polarity
For a 3-wire connection: respect the polarity

1.3 Remote Input Wiring
The TH140 is equipped with a remote input which allows connec-
tion of a telephone controller (optional Aube CT240), a home auto-
mation system or any other remote control system. When a signal is
received through this input, the TH140 will automatically switch
from normal operating mode to Vacation mode, or vice versa when
the signal is removed.
1.3.1 Connection to the CT240
Connect CT240 terminals A and C to
TH140 terminals X and C. You must
respect the polarity.
For details on operating the telephone
controller, refer to the instruction manual.
1.3.2 Connection to a home automation system
Connect the TH140
to the home automa-
tion system as dis-
played in the wiring
diagram.
1.4 Configure the Thermostat
Before mounting the control module on the base, you may need to
modify some of the default settings. The switches are located on
the back of the control module. Default settings are highlighted.
1.4.1 Proportional Adaptive Mode (switch #5)
This mode analyzes previous cycles to define the length of the
upcoming cycle. This control mode guarantees optimal temperature
control based on the system’s capacity. To extend the life of the
system, a minimum On/Off time of 10% of the cycle has been
implemented. For example with a 15-minute cycle, the system
would not start or stop for less than 1.5 minutes.
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.
Not recommended for:
• Gas or fuel furnace or boiler with a wall chimney having a
30-second or higher combustion gas purging cycle. To figure out
the gas purging cycle of your system, count the time 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 sin-
gle heating unit.
Note: In these last two cases, conventional mode with anticipation
is recommended.
Heating Cycle Selection (switches #1 and #2)
In proportional adaptive mode, the TH140 adapts the control cycles
to the system’s capacity. Short cycles help eliminate temperature
variations, thus increasing user comfort. Since shorter cycles can
lead to premature system wear, it is important to select the
temperature control cycles appropriate to your heating system. In
general, the bigger your heating unit is, the longer the cycles should
be.
Select the cycle using switches #1 and #2. We recommend the
following options:
1.4.2 Conventional mode with anticipation (switch #5)
If you choose conventional mode with anticipation, it is possible to
program a span (temperature variations between ON and OFF
orders of your system). This mode is compatible with all heating
systems.
Programmable Span Selection (switches #1 and #2)
The default temperature span is 0.9°F. For example, if the tempera-
ture setpoint is 68°F, the heating system will turn on at 67.1°F and
turn off at 68.9°F.
Select the cycle using switches #1 and #2. We recommend the fol-
lowing options:
1.5 Install the Batteries
When you first install the batteries, the unit runs a
sequence of tests and a complete reset to zero.
The screen should display 0:00 MO and the
ambient temperature. The current setpoint is 20°C.
The ambient temperature could be higher if you
are holding the TH140 in your hands. It will return
to normal about one hour after installation.

1.5.1 Replacing the batteries
The TH140 will display an icon indicat-
ing that the batteries must be replaced.
This icon will be displayed for 60 days;
after this delay, the TH140 will shut
down the heating unit.
The time and programming are saved
for 15 seconds when replacing the batteries.
Note: You may program the thermostat while holding it in your
hands or when it is mounted on the mounting plate.

indicates a setpoint.
The TH140 offers three operating modes:
3.1 Automatic
This mode executes the schedule.
To activate:
• Press MANUAL/AUTO until is displayed.
The program setpoint icon is displayed.
3.1.1 Temporary Bypass
When in Automatic mode, you can temporarily
bypass the current program setpoint until the
beginning of the next program. To bypass:
• Set the desired temperature OR quickly press or to
use a pre-defined setpoint.
3.2 Manual
This mode allows you to maintain a constant tem-
perature. To activate this mode:
• Press MANUAL/AUTO until is displayed.
• Set temperature OR quickly press or

3.3 Vacation
Maintains a specific temperature when away for a
prolonged absence (e.g. vacation).
• From the TH140, quickly press to activate.
• Can also be activated remotely (CT240, home
automation system or any other system) if the
remote input is connected to one of these sys-
tems.
Note: When the Vacation mode is activated remotely, it can only be
deactivated remotely.
Note: For details on how to activate the Vacation mode using a
telephone, refer to the CT240 Instruction Manual.
The TH140 allows four setting changes for each day of the week.
There are no pre-set programs. The programs can be tailored to fit
your life style.
For each day, enter the time at which you wake up (PROG 1), the
time you leave for work (PROG 2), the time you return home
(PROG 3) and the time you go to bed (PROG 4):
Note: For temperature increases (PROG 1 and 3), allow at least
15 minutes per °C. For example, if you have lowered the
temperature by 3°C during the night and you wake up at
7 a.m., change the setting at 6:15 a.m.
