Aube TH141-HC-28 Programmable Thermostat

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.

(Rh) Red	Heating power source
(W) White	Heating relay
(Rc) Blue	Air conditioning power supply

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.

5-minute cycle:	For specific applications only
10-minute cycle:	Radiant or convection electric heating
15-minute cycle:	Central heating and air-conditioning unit
20-minute cycle:	Commercial unit

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.

Variations	Hot-Water Heating	Heating and Air-conditioning
0.3 °C/ 0.5 °F	For specific applications only	For specific applications only
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

Note: 240 volt heating with relay (baseboard, convector, radiant ceiling, etc.)

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.

Programming the time and day

1. Set the time using the Hour and Minute buttons.
2. Set the day using the Day button.

Programming the comfort, economy, and vacation settings
The Comfort,  Economy, 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 tube technologies TH141-HC-28 Programmable HVAC Thermostat Auto Change Remote Input – Fig 31. Since your thermostat controls both heating and air conditioning, and since the economy 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.
Program the heating settings

1. Set your thermostat to the heating mode using the Heat/Cool button.
2. To program the Comfort temperature, select the desired degree using the buttons and press the button until the icon is displayed (approximately 3 seconds).
3. To program the Economy temperature, select the desired degree using the buttons and press the button until the icon is displayed (approximately 3 seconds).
4. To program the Vacation temperature, select the desired degree using the buttons and press on the button until the icon is displayed (approximately 3 seconds). This setting is used by the telephone remote control.

Program the air-conditioning settings
Set your thermostat to the air-conditioning mode using the Heat/Cool button and repeat steps 2 to 5 of section 2.2.1.

Operating modes

The TH141 offers two operating modes.
Manual (2 )

1. This mode allows you to maintain a constant temperature in the house. To activate this mode, press the Manual/Auto button to display the icon.
2. Set the desired temperature by pressing the buttons or by briefly pressing the or button.

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).

Program	Mode	Time
1		Wake-up time
2		Leaving time
3		Return time
4		Bedtime

NOTE: For temperature increases (Program 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.
