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. Loosen the captive screw holding the faceplate to the mounting plate.
2. Pull the lower part to separate the faceplate from the mounting plate.
3. Fix the mounting plate onto the wall using the supplied screws.

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 opening is bigger 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.

1.5 Connect the labeled wires to the thermostat

1. Connect the system wires to the thermostat terminals according of the wiring diagrams in the section
2. Make sure to return the remaining wire length to the wall.
3. If you own a CT240 telephone controller, refer to section 6.1 for connection.

Wiring diagrams

Thermostat configuration

Configure the thermostat using the DIP switches on the back side of the faceplate.
24 hr. or 12 hr. Display

The TH141 offers a 12 hr. or 24 hr. mode display. The default configuration of the display is in the 24 hr. mode. If you prefer a 12 hr. display, push switch

3 up.

The temperature in °C or °F

The default configuration of the TH141 is at °C. If you wish to change the temperature to °F, push switch #4 up. If you change from °F to °C (or vice versa), you will need to reprogram your comfort and economy settings.
Regulation Modes

You have a choice between two regulation modes:

• Proportional adaptive mode
• Conventional mode with anticipation

Proportional adaptive mode

If you want the proportional adaptive mode, push switch #5 up. This mode analyses previous cycles to define the next duty 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 Cycle Length
Set the length of the regulation cycles using switches #1 and #2. 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 of your system. It is therefore important to adjust the cycles to your type of installation. In general, the bigger your eating r  air-conditioning unit, the longer the cycles should be.

Conventional mode with anticipation
If you want the conventional mode with anticipation, push switch #5 down. This mode maintains the temperature within the programmed span. This model is compatible with ll heating or air-conditioning systems.
Programmable Span
Use switches #1 and #2 to select the appropriate temperature span.

  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 eating unit. However, if the fan does not turn on and the thermostat requires heating for more than one minute, push switch #6 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 still 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 when it is mounted on the wall.
