Installation

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 concealed
chimneys or stove pipes.

1.3 Remote Input Wiring

The TH140 is equipped with a remote input which allows conne ction
of a telephone controller (optional Aube CT240), a home automation
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 auto­mation system as displayed in the wir­ing diagram.

Home automation system

1.4 Configure the Thermostat

The switches are located on the back of the faceplate. Default set­tings are highlighted.

Heating Cycle Selection (switches #1 and #2)

Select the cycle using switches #1 and #2. 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.

1.4.1 Proportional Adaptive Mode (switch #5)

This mode analyzes previous cycles to define the the next duty 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

• Conventional gas or fuel hot-air 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 single
heating unit.

Note: In these last two cases, conventional mode with anticipation is

recommended.

Programmable Span Selection (switches #1 and #2)

Select the span using switches #1 and #2. The default temperature
span is 0.5°C (0.9°F). For example, if the temperature setpoint is
20°C (68°F), the heating system will turn on at 19.5°C (67.1°F) and
turn off at 20.5°C (68.9°F).

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 abou t one
hour after installation.

1.5.1 Replacing the batteries

The TH140 will display an icon indicating 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.

• 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 systems.

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 tele-

phone, refer to the CT240 Instruction Manual.

The TH140 allows four setting changes for each day of the week .
There are no pre-set programs. Your heating system switches betw­wen the Comfort setpoint and the Economy setpoint according to the
times you would have set.

For example, enter each day 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):
