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 out-

let), dead air spots (behind a door), direct sunlight or concealed

chimneys or stove pipes.

nLoosen the captive screw holding the faceplate to the mounting

plate.

oPull the lower part of the faceplate to remove it from the mount-

ing plate.

pLoosen the screw (captive) holding the wire cover and remove

the wire cover.

qPull wires through the hole in the mounting plate and secure the

mounting plate to the wall (or onto an electrical box for line volt-

age wiring) using the enclosed wall anchors and screws.

rWire the thermostat to the heating system (see section 1.2) and,

if necessary, connect the remote input (see section 1.3).

sOnce wiring is complete, re-install the wire cover.

tUse the switches located at the back of the faceplate to config-

ure your thermostat (see section 1.4) according to your applica-

tion.

uInstall the batteries (see section 1.5).

vMount the faceplate on the mounting plate and tighten 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: observe the polarity

1.3 Remote Input Wiring

The TH140 is equipped with a remote input which allows connection

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 sig-

nal 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 control-

ler, refer to the instruction manual.

1.3.2 Connection to a home automation system

Connect the TH140 to the home auto-

mation system as displayed in the wir-

ing diagram.

1.4 Configure the Thermostat

The switches are located on the back of the faceplate. Default set-

tings are highlighted.

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-sec-

ond 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.

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.

1.4.2 Conventional mode with anticipation (switch #5)

This mode is compatible with all heating systems.

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 tem-

perature. 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 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.

Note: You may program the thermostat while holding it in your hands

or when it is mounted on the mounting plate.

2.1 Set the Time and Day

nSet the time, using the Hour and Minute buttons.

oSet the day, using the Day button.

2.2 Configure the Setpoints

2.2.1 Comfort and Economy

These setpoints are associated to the schedule’s programs and are

pre-programmed as follows:

2.2.2 Vacation

This pre-programmed setpoint is used when the Vacation mode is

activated.

2.2.3 To Modify a Setpoint

nSet the temperature using .

oPress and hold one of the setpoint

buttons ( or or ) until the

icon is displayed on the screen

(approx. 3 seconds).

2.3 View the Current Setpoint

To view the current setpoint, quickly press

once one of the arrow buttons .

The screen displays the setpoint; the arrow

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 temperature.

To activate this mode:

• Press Manual/Auto until is displayed.

• Set temperature OR quickly press or to use

a pre-defined setpoint.

3.3 Vacation

Maintains a specific temperature when away for a pro-

longed absence (e.g. vacation).

• From the TH140, quickly press to activate.

• Can also be activated remotely (CT240, home automa-

tion 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 betw-

wen 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):

Note: For temperature increases (PROG 1 and 3), allow at least

15 minutes per 1°C (2°F). For example, if you have lowered

the temperature by 3°C (6°F) while you sleep and you wake up

at 7 a.m., change the setting at 6:15 a.m.
