INTRODUCTION
This thermostat can replace most common residential thermostats
and is designed to be used with electric, gas or oil heating and air
conditioning systems using 24 volts control and relay current up to
1.0 ampere.
Several useful functions and operating modes have been incorporated to adapt a variety of customer needs: besides all the features
associated with the state of the art programmable thermostat, you’ll
find on TH123:
•
a 7 day timer to set the ECONO mode during a prolonged
absence.
•
a signal entry to remotely control the ECONO mode.
•
a protection against freezing.
•
a filter supervision.
•
a programmable regulation sensibility (SPAN).
To protect the compressor from damage and wear by cycling on
and off too rapidly, the TH123 incorporates a minimum five (5) minutes delay between cooling cycles.
If you have any questions concerning the installation or programming of the thermostat, please call our technical assistance at
1-800-831-AUBE or for the Montreal area, (450) 358-4600 from
8:30 AM to 5:00 PM, Monday through Friday, Eastern time.

REMOVING YOUR OLD THERMOSTAT
WARNING: To avoid electric shock, turn off the power of the
heating and cooling system at the main power box in your home.
Read the following instructions carefully before disconnecting the
wires.
n Turn off your old thermostat.
o Remove the cover from the old thermostat. You may have to
pull extra hard.
p Unscrew the old thermostat from the wall plate
q Now find the screws attaching the wall plate to the wall, and
remove them. You should now be able to pull the wall plate a
small distance from the wall. Do not disconnect any wires yet,
simply locate the wires.
Note: If your old thermostat has only two (2) wires connected to it
(heating system only), simply disconnect the two wires from the wall
plate, skip over steps 1 and 2 in the Wire labelling section and go on
to step 3.
WARNING: After removing the wall plate, if you find that it is
mounted on a junction box (e.g. a box similar to one behind a light
switch or electric outlet), 240 volts circuit may be present and there
is a danger of electric shock. Please consult a qualified electrician.
WIRE LABELLING
n If your old thermostat wall plate has more than two wires connected to it, then you will need to label the wires. First look for
LETTER near each terminal where a wire is connected. These
terminals and markings may be on either side of the wall plate.
Disconnect and identify each wire.
o
p You may wish to tape the wires to the wall to keep them from
slipping through the hole in the wall. If the hole in the wall is
larger than necessary, fill it in order to prevent hot or cold air to
penetrate the thermostat. In this manner, the thermostat will
behave perfectly.
CHOOSING A LOCATION
q Turn on the main switch of the system. The thermostat is ready
for use.
WIRING DIAGRAM
The TH123 thermostat can be used with any single stage heating
and cooling system. You cannot directly use this thermostat on multiple stages heating or cooling system, millivolt system, heat pump
or 240 VAC control system. It can control some of those systems by
installing an isolation relay and a 24-volt transformer.
HEATING SYSTEM TYPE
The heating system type selector is located below the wire connector. Start first by keeping the selector at default position Hg. If the
fan switch is at FAN AUTO position and the fan doesn’t start when
the thermostat turns on the furnace, place the type selector at position He.
2-WIRE HEATING SYSTEM
Note: For a new installation, choose a mounting location about five
feet (150 cm) above the floor in an area with good air circulation and
away from:
Drafts or dead air spots, Air ducts, radiant heat from the sun or
appliances, Concealed pipes and chimneys.
Mounting the thermostat onto the wall
n Remove completely the slide door of the thermostat.
o Unscrew and remove the cover over the connector.
p Mark the holes posi-
q
r
tion and align the wire
coming from the wall
in the hole beside the
connectors.
Drill two holes and
insert the plastic
anchors carefully into
the holes until they are
flush with the wall.
Fasten securely the thermostat to the wall with the two (2)
screws.
n Connect the heating relay to terminal W.
o Connect the 24 VAC transformer to terminal Rh.
3-WIRE HEATING SYSTEM WITH FAN CONTROL
DISPLAY IN °C OR °F
After the installation of the battery, if
you want to change unit of the degree
displayed, follow these instructions
(see the illustration):
n From the back of the thermostat,
unscrew the cover.
o For the °C display, the jumper in
JP1 is installed.
p For the °F display, the jumper in JP1 is removed.
q Re-install the cover in place.
n Connect the heating relay to terminal W.
o Connect the fan relay to terminal G.
p Connect the 24 VAC transformer to terminal Rh.
4-WIRE HEATING AND COOLING SYSTEM
r Press on the reset button.
CONNECTING THE LABELLED WIRES TO THE THERMOSTAT
n Connect the system wires to the terminals according to the wiring diagram shown in the section “wiring diagram”.
WARNING: Do not remove the jumper between terminals Rh and
Rc unless otherwise specified.
o Push on the wires in the wall and replace the cover over the
connectors.
p Install two (2) “AA” size batteries into the battery compartment.

your thermostat will operate without batteries, it is recommended to
replace the batteries when the display is showing “BATT”.
OPERATING MODES
The thermostat has four (4) operating modes: AUTOmatic, MANual,
TIMER ECONO and REMOTE ECONO.
AUTO
The AUTOmatic mode executes in sequence (hourly)
the recorded programs.

Ͽ
WARNING: Remove jumper between terminals Rh and Rc: Both 24
volts returns of the transformers must be connected together in
order to have the fan working with the heating and the cooling
system. *Otherwise, the fan will only work with the cooling system.
*(both transformer supplies, 120/240 vac, must be the same).

REMOTE ECONO MODE
Connect the auxiliary system (alarm or domotic system for instance)
between the terminals X (positive) and C (negative). The signal
from those systems must be 12 to 24 VAC or VDC.
Press on the AUTO button. The “PROG” icon and
the running program will be displayed.
Pressing
or

TIMER ECONO
The TIMER ECONO mode holds the ECONO temperature set point until user predetermined
time and day is reached. Then, the thermostat turns to
AUTOmatic mode.
This operating mode avoids the user to reprogram his
thermostat for a prolonged absence (up to one week)
and allows for maximum savings.

REMOTE ECONO
An auxiliary system as your alarm or domotic system for instance,
can turn your thermostat to ECONO mode. The thermostat holds
the ECONO temperature set point as long as the signal of the auxiliary system is applied.
The
icon is flashing to indicate that the auxiliary signal is
present.
When the auxiliary signal is removed, the thermostat returns to the
previous operating mode (see wiring diagram).
FIRST POWER-UP
FUNCTION SWITCH
When power is applied for the first time, the display
must show time and day as well as the ambient
temperature as follows:
If the display is different, press the RESET button.
Use a fine probe such as straightened paper clip to
gently push the RESET button.
This switch selects the functions: HEAT, COOL, and OFF.
HEAT:
Select that position to control the heating system. In
AUTO mode, the thermostat will refer to heating programs to control the temperature.
Note: Your thermostat is using two (2) “AA” size
batteries to protect its memory against a power failure. Even though
COOL:
Select that position to control the cooling system. In
AUTO mode, the thermostat will refer to cooling programs to control the temperature.
OFF:
This function shuts off the heating and cooling systems.
This function holds the temperature setpoint at 5°C
(40°F) (heating) in order to prevent freezing. It is not
programmable.
FILTER:
The thermostat keeps a record of the number of hours
your filter has been used. It will display the total number
of hours the system has used the filter from the moment
the filter was replaced and that the filter counter was
reset to zero. After 250 hours of system operation, the
FILTER indicator will begin flashing, to remind you to
change or clean the filter and to reset the filter counter
back to zero. The filter counter will count up to a maximum 999 hours and stays there until you reset it again.
To reset the counter, press and hold the FILTER key
until the display shows 000.
