Installation

Note: The installation must be performed by an electrician.

Removing the Old Thermostat
IN ORDER TO AVOID ANY RISK OF ELECTRIC SHOCK, CUT POWER TO THE HEATING SYSTEM.

• Remove the old thermostat to access the wires.
• Identify and label each wire (with the corresponding letter on the wire terminal) and remove them from the terminals.
• If necessary, strip the end of each wire (maximum of 6 mm).

Installing the New Baseplate
Choose a location approximately 1.5 m above the floor and on an inside wall. Avoid draughty areas (top of staircase, air outlet, etc.), dead air spots (behind doors), direct sunlight or areas near concealed pipes or chimneys.

1. Remove the thermostat faceplate.
2. Loosen the locking screw in order to separate the thermostat from its baseplate (the screw cannot be completely removed).
3. Gently tilt the thermostat upwards.
4. Pass the wires through the opening of the baseplate and secure the baseplate to the wall using the appropriate screws.

Connecting the Heating System

Unoccupied Mode Input (TH148ELE-P only)

TH148ELE-P has an input that can be used to lower the temperature when the house is unoccupied. You can connect an Aube’s CT240 telephone controller (optional) or another remote control system.
When the thermostat receives a 12-VDC signal, it switches to the unoccupied mode where the setpoint programmed for that mode is used (see section 5). When the signal is removed, the thermostat returns to the previous mode.

Connecting to CT240 
Connect TH148ELE-P terminals UN and UN to CT240 terminals A and C (no polarity to observe).

Connecting to a Home Automation System
Connect TH148ELE-P terminals UN and UN to a 12-VDC circuit as shown (no polarity to observe).

Installing the Batteries:

1. Gently pull out the battery cover.
2. Install the batteries as shown. Observe the polarity.
3. Re-install the battery cover. You will hear a clicking sound.

After the batteries are installed, the thermostat performs a series of tests for approximately 5 seconds.
Afterwards, the thermostat displays the temperature. It is possible that the displayed temperature is higher than the ambient temperature if you are holding the thermostat in your hands. Once installed on the wall, the thermostat will display the ambient temperature. The time and day settings flash to indicate that they must be set (see sec-tion 4.1).

Completing the Installation

Basic Functions

Backlight 
The display illuminates for 12 seconds when the backlight button or any other button is pressed.

Displaying the Temperature
The actual (measured) temperature is normally displayed. To view the setpoint temperature, press once on either of the buttons. The setpoint, along with the icon, will be displayed for the next 5 seconds.

Setting the Temperature 
Press one of the buttons until the desired temperature is displayed.

Comfort and Economy
Temperatures The thermostat has 2 preset temperature buttons:

• Comfort temperature
• Economy temperature

To set the thermostat at the Comfort or Economy temperature, press the corresponding preset button. The corresponding symbol will be displayed.
The following table shows the use and the factory setting of each preset button.

Button	Intended use	Default setting
	Comfort (when the occupant is awake and at home)	21°C
	Economy (when the occupant is absent or asleep)	17°C

To modify the Comfort or Economy temperature:

• Set the desired temperature using the buttons.
• Press and hold the appropriate preset button until the corresponding symbol is displayed.

Control Mode

Manual
Use this mode to set the temperature manually. To use this mode, press Mode to display and set the desired temperature using the buttons or the buttons.

Automatic
Use this mode to set the temperature according to the programmed schedule (see section 4.3). To place in Automatic mode, press Mode to display .
Temporary Bypass
If you modify the setpoint temperature when the thermostat is in automatic mode, the new temperature will be used for the next 2 hours. Afterwards the thermostat will return to the automatic
mode and use its current temperature setting. The icon flashes during the bypass.

Unoccupied (TH148ELE-P only)
To place the thermostat in Unoccupied mode, see section 2.5. When the thermostat is in this mode, the unoccupied mode setpoint is used and the icon is displayed.
Temporary Bypass
If you modify the setpoint temperature when the thermostat is in unoccupied mode, the new temperature will be used for the next 2 hours. Afterwards, the thermostat will return to the unoccupied
mode setpoint. The icon flashes during the bypass.

Low-battery Indicator
An icon appears when the batteries need replacement. This icon will flash for 60 days, then the thermostat will cut power to the heating system. The icon disappears once the batteries are replaced. After replacing the batteries, re-adjust the clock and day (see section 4.1). For TH148ELE-P model, re-adjust the date also
(see section 4.2). The rest of the settings are unaffected when the batteries are removed.
