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.

Please note that if you change from °F to °C (or vice versa), your comfort and econ-
omy settings will need to be reconfigured as well.
2.
For hot water installations, it is recommended enabling this option to activate the
pump for one minute every 24 hours in order to avoid any seizing.
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:
Cycles
5 minutes
10 minutes
15 minutes
20 minutes
1.4.2 Conventional mode with anticipation (switch #5)
If you choose conventional mode with anticipation, it is possible to
DOWN
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)
24H
The default temperature span is 0.9°F. For example, if the tempera-
°C
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:
Span

(0.3°C)
0.7°F
(0.4°C)
0.9°F

240 volt heating with relay (baseboard, convector, radiant ceiling, etc.)
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
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.
