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

  1. Cut the power source to your heating or air conditioning system.
  2. 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

  1. Remove the screw holding the thermostat mounting plate.
  2. Lift the lower part to separate the plate from the thermostat.
  3. Mount the plate on the wall using the screws suppliedAube Technologies-TH141-HC-28-Programmable-Thermostat-fig-1

IDENTIFY THE WIRES

  1. 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.
  2. Disconnect and identify each wire*.
  3. 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

  1. Connect the system wires to the thermostat terminals according to the wiring the diagram is shown in section 1.6.
  2. Make sure that the wires are pushed well back into the wall.
  3. If you own a CT240 telephone controller, refer to section 6.1 for connection.

 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

Aube Technologies-TH141-HC-28-Programmable-Thermostat-fig-7

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.

Aube Technologies-TH141-HC-28-Programmable-Thermostat-fig-8

Regulation Modes
You have a choice between two regulation modes:

 

Proportional adaptive modeAube Technologies-TH141-HC-28-Programmable-Thermostat-fig-8

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)

Aube Technologies-TH141-HC-28-Programmable-Thermostat-fig-10

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:

Aube Technologies-TH141-HC-28-Programmable-Thermostat-fig-10

  • 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

Aube Technologies-TH141-HC-28-Programmable-Thermostat-fig-12Conventional 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.)

VARIATIONS HOT-WATER HEATING HEATING AND AIRCONDITIONING
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

Aube Technologies-TH141-HC-28-Programmable-Thermostat-fig-14Heating 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.

Aube Technologies-TH141-HC-28-Programmable-Thermostat-fig-15

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.
