We thank you for trusting Aube Technologies and hope that you will be entirely satisfied. For any questions concerning the TH141A-HC-28 programmable electronic thermostat, please call our Technical Support Department at 1-800-831-AUBE (2823) Montreal Area : (450) 358-4600
INSTALLATION
REMOVE THE OLD THERMOSTAT
- Cut the power source to your heating or air conditioning system.
- Remove the cover of the old thermostat.
Caution: If, upon removing the wall plate, you see that it is mounted on a junction box (similar to the junction box located behind an electrical switch or outlet), this may indicate that it is a 120 V/240 V system. For more security, consult a qualified electrician to check the installation.
INSTALL THE NEW THERMOSTAT
For a new installation, choose a location about 1.5 meters (5 feet) above the floor, with good air circulation. The thermostat must be installed on an inside wall. Avoid locations where there are:
- air drafts (top of a staircase, air outlet,…)
- dead air spots (behind a door,…)
- direct sunlight
- concealed chimneys or stove pipes.
INSTALL AND CONNECT THE THERMOSTAT
- Remove the screw holding the thermostat mounting plate.
- Lift the lower part to separate the plate from the thermostat.
- Mount the plate on the wall using the screws supplied
IDENTIFY THE WIRES
- If the wall plate of your old thermostat has more than two wires coming out of the wall, you will need to label the wires. Start by identifying the letters close to each screw or terminal on which a wire is connected. These terminals may be located on either side of the plate.
- Disconnect and identify each wire*.
- You may need to tape the wires to the wall to keep them from falling back into it. If the wall cavity is larger than necessary, fill it with insulating wool in order to prevent the infiltration of warm or cold air behind the thermostat.
If your installation is recent, the color of the wires should match the identification on the mounting plate.
- (Rh) Red Heating power source
- (W) White Heating relay
- (Rc) Blue Air conditioning power supply
- (Y) Yellow Air conditioning relay
- (G) Green Fan relay
CONNECT THE LABELLED WIRES TO THE THERMOSTAT
- Connect the system wires to the thermostat terminals according to the wiring the diagram is shown in section 1.6.
- Make sure that the wires are pushed well back into the wall.
- If you own a CT240 telephone controller, refer to section 6.1 for connection.
WIRING DIAGRAMS
The TH141 thermostat is compatible with most heating and air conditioning
systems. Multi-level heating and air conditioning systems, Milivolt control
heating systems, heat pumps, and baseboard heating units are not compatible
with this thermostat. Baseboard units can be connected using a 24 V relay.

THERMOSTAT CONFIGURATION
Before mounting the thermostat on the wall, configure it using the switch bank
on the back side of the unit.
24 hrs. or 12 hrs. Display
The TH141 offers a 12 hrs. or 24 hrs. mode display. The default configuration
of the display is in the 24 hrs. mode. If you prefer a 12 hrs. display, push
3 to switch up
Temperature in °C or °F
The default configuration of the TH141 is in °C. If you wish to change the
temperature to °F, push the #4 switch up. Please note that if you change from
°F to °C, your comfort and economy settings will need to be reconfigured as
well.
Regulation Modes
You have a choice between two regulation modes:
Proportional adaptive mode
If you want the proportional adaptive mode, push #5 switch up This mode analyses previous cycles in order to define the length of the upcoming cycle. This operating mode guarantees optimal regulation based on the capacity of your system. To avoid cycles that are too short for the heating or air- conditioning units, the minimum On and Off duration is limited to 10% of the period (1.5 minutes for a 15-minute cycle)
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
- Air-conditioning system
- Not recommended for: Gas or fuel furnace or boiler with wall chimney, if they include a combustion gas purging cycle exceeding 30 seconds. To verify this point, check the duration of the delay 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 or air conditioning unit.
- In the last two cases, the conventional mode is recommended.
Regulation Cycles
In proportional adaptive mode, the TH141 adapts the regulation cycles to your
system capacity. When cycles are very short, the temperature variation in the
room is very low and the comfort level very high. However, very short cycles
can generate premature wear in your system. It is therefore important to
adjust the cycles to your type of installation. In general, the bigger your
heating or air-conditioning unit, the longer the cycles should be. The TH141
offers the possibility of programming regulation periods of 5, 10, 15, or 20
minutes using switches 1 and 2 at the back of the unit.
We recommend the following options:
- 5-minute cycle Not recommended for central units
- 10-minute cycle for Radiant or convection electric heating
- 15-minute cycle for Central heating and air-conditioning unit
- 20-minute cycle for Commercial unit
Conventional mode with anticipation
If you want the conventional mode with anticipation, push the #5 switch down.
This mode commands the system’s On and Off cycles when the temperature read by
the thermostat reaches pre-set levels. This model is compatible with all
heating or air-conditioning systems.
Programmable Span
When the thermostat is in conventional mode with anticipation, it is possible
to program a span, that is temperature variations between ON and OFF orders of
your system. These variations are programmable between 0.3 and 0.6 °C (0.5 and
1.1 °F) and they correspond to the following positions of switches #1 and #2:
We recommend the following options: 240-volt heating with relay (baseboard,
convector, radiant ceiling, etc.)
V ARIATIONS| H OT -W ATER H EATING| H
EATING AND A IR – CONDITIONING
---|---|---
0.3 °C/ 0.5 °F| Not recommended for furnaces| Not recommended for central
units
0.4 °C/ 0.7 °F| Gas or electric wall furnace| Radiant or convection electric
heating *
0.5 °C/ 0.9 °F| Fuel or gas floor furnace| Central heating or air-conditioning
unit
0.6 °C/ 1.1 °F| Commercial unit| Commercial unit
Heating Fan Control
This function determines whether the heating system fan is operated by the
thermostat or by the plenum’s temperature of the heating unit. In general, the
fan is operated by the heating unit. However, if the fan does not turn on and
the thermostat requires heating for more than one minute, push the #6 switch
up
BATTERY INSTALLATION
When you first install the batteries in the TH141, the unit runs a sequence of
tests and a complete reset to zero, which last approximately 5 seconds. The
screen should display the time and the day, as well as the current temperature
as follows: It is normal for the displayed temperature to be higher than the
room temperature if you are holding the TH141 in your hands, It will return to
normal about one hour after installation on the wall. Mount the thermostat on
the wall plate and screw it in place.
Even if the thermostat indicates that the batteries are good, it is recommended to replace them once a year, at the beginning of the cold season.
ENTRY OF BASIC DATA
You may program the thermostat while holding it in your hands or once it is
mounted on the wall.
PROGRAMMING THE TIME AND DAY
- Set the time using the Hour and Minute buttons.
- Set the date using the Day button.
PROGRAMMING THE COMFORT, ECONOMIC, AND VACATION SETTINGS
The Comfort , Economic , and Vacation settings respectively represent the
temperatures that you wish to have during the day , at night or while you are
away at work , or while you are away for an extended period. Since your
thermostat controls both heating and air-conditioning and since the economic
settings are the opposite in both cases (reduction for heating temperature,
increase for air-conditioning), you must program the settings for heating and
then for air-conditioning
To program your heating settings
- Set your thermostat to the heating mode using the Heat/Cool button.
- To program the Comfort temperature, select the desired degree using the buttons and press the button until the icon is displayed (app. 3 seconds).
- To program the Economic temperature, select the desired degree using the buttons and press the button until the icon is displayed (app. 3 seconds).

setting is active.
SCHEDULE PROGRAMMING
The TH141 allows 4 setting changes for each day of the week. There are no pre-
set programs. The programs are tailored to perfectly adapt to your lifestyle.
The principle is very simple. For each day, enter the time at which you wake
up (P1),
the time you leave for work (P2), the time you arrive back home (P3), and the
time you go to bed (P4).
Note: For temperature increases (Prog. 1 and 3), allow at least 15
minutes per °C. If you have lowered the temperature by 3 °C during the night
and you wake up at 7 AM, change the setting to 6:15 AM. For savings to be
obtained, you must lower the temperature for a period of 2 to 3 times the
delay required to bring the temperature back to your comfort level.
Example: If your system takes one hour to go from your saving temperature
level to your comfort temperature level, it is useless to lower the
temperature for a period of 2 to 3 hours.
