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
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.
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:
INSTALL AND CONNECT THE THERMOSTAT
If your installation is recent, the color of the wires should match the identification on the mounting plate.
CONNECT THE LABELLED WIRES TO THE THERMOSTAT
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:
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
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:
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.)
VARIATIONS | HOT-WATER HEATING | HEATING AND AIR–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 |
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.

OPERATING MODES
The TH141 offers two operating modes.
MANUAL
This mode allows you to maintain a constant temperature in the house.
AUTOMATIC
This mode executes your own programming. To activate this mode, press the Manual/Auto button to display the
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.
To Program Your Schedule
To Erase a Program
Select the program using the Program and Day buttons, and press the Clear button. The time zone displays –:– when the program is inactive. Example 1: Comfort period from 7:00 AM to 10:30 PM The economy period from 10:30 PM to 7:00 AM Identical schedule for all days of the week.
Example 2: Comfort period: Monday to Friday from 6:15 AM to 8:15 AM and from 5:00 PM to 10:00 PM

TEMPORARY OR PERMANENT TEMPERATURE BYPASS
This operation allows you to temporarily modify the room temperature while you are in automatic mode. Simply press the buttons to select the desired temperature, or the or button to select the Comfort or Econo settings you have programmed. This temperature will be maintained until the beginning of the next programmed schedule. You can also switch to the Vacation setting for a prolonged absence by pressing the button. In that case, the derogation is permanent. To return to the normal operating mode, press the Manual/Auto button. If you wish to immediately return to the programmed settings, press the Manual/Auto button twice.
SELECT THE HEATING, AIR CONDITIONING, OR MIXED MODE
Use the Heat/Cool button to select one of the following modes:
FAN CONTROL
Use the Fan ON/OFF button to force continuous air circulation (icon
TELEPHONE CONTROLLER
The TH141 incorporates a telephone controller interface that allows you to switch from the normal operating mode to the Vacation setting (
CONNECTION TO THE CT240
The TH141 is designed to connect directly to the CT240 telephone controller. This combination allows the activation and deactivation of the Vacation mode from the CT240 or the telephone. Connect the CT240’s terminals A and C to the TH141’s terminals X and C respectively. You must respect the polarity. For details on operating the telephone controller, refer to CT240’s Instruction Manual.
CONNECTION TO A HOUSE AUTOMATION SYSTEM
The Vacation setting can also be activated from a house automation system.
OPERATING THE TELEPHONE INTERFACE
You can activate the Vacation setting using the Vacation button of the telephone controller or using the telephone itself.
BATTERY REPLACEMENT
The TH141 will display an icon indicating that the batteries must be replaced. This icon will flash for 60 days. After this delay, the thermostat will shut down your heating unit. During battery replacement, the data is kept for of 15 seconds. The time and the programs will not be lost. After this delay, the TH141 runs a sequence of tests and a complete reset to zero for the initial installation of the batteries. Even if the thermostat indicates that the batteries are good, it is recommended to replace them once a year
