Installation

Note: The installation must be performed by an electrician or a qualified installer.

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

• Remove the old thermostat to access the wires.
  Attention: If the old thermostat was mounted onto an electrical box, it might have been powered by 120/240 volts. In this case, the TH147-P or TH148LE-P thermostat cannot be used.
• 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).
• Wrap the wires around a pencil to prevent them from falling into the wall.
• If the hole in the wall is too big, insulate it using a non-flammable material in order to avoid air draughts behind the thermostat.

 

Installing the New Baseplate
For a new installation, choose a location approximately 1.5 m (5 feet) above the floor and on an inside wall. Avoid draughty areas (top of the staircase, air outlet, etc), dead air spots (behind doors), direct sunlight or areas near concealed pipes or chimneys.

1. remove the thermostat faceplate.  Loosen the locking screw in order to separate the thermostat from its baseplate (the screw cannot be completely removed).
2. Gently tilt the thermostat upwards. Mark and bore the appropriate mounting holes (or use the existing holes). Insert the plastic anchors. Pass the wires through the opening of the baseplate and fix the baseplate to the wall using the screws provided.
3. Gently tilt the thermostat upwards.
4. Mark and bore the appropriate mounting holes (or use the existing holes). Insert the plastic anchors.
5. Pass the wires through the opening of the baseplate and fix the baseplate to the wall using the screws provided.

Note: Remove the red jumper wire between terminals Rc and Rh.

Remote Control Input (TH148LE-P only)
The TH148LE-P thermostat has an input to which a CT240 telephone controller (optional) or any other remote control system (e.g., home automation) can be connected. When the input receives a 12-VDC signal, the thermostat switches from its current mode to the unoccupied mode and vice versa when the signal is removed. The unoccupied mode can be used to re-adjust the temperature to save energy when you are away for an extended period of time. To set the unoccupied mode temperature, see section 4.

 Connecting to CT240
Connect TH148LE-P terminals UN and UN to CT240 terminals A and C (no polarity to observe).

Connecting to a Home Automation System
Connect TH148LE-P terminals UN and UN to a 12-VDC circuit as shown.

Setting JP2 Jumper
The jumper specifies how the fan will operate when it is placed in automatic mode.

HG	Leave the jumper in this position if you have a gas or fuel oil furnace.
HE	Place the jumper in this position if you have an electric furnace.

Installing the Batteries

1. Gently pull out the battery cover.
2. Install the batteries as shown. Observe the polarity.
3. Reinstall the battery cover. You will hear a clicking sound.
4. After the batteries are installed, the thermostat performs a sequence of tests for approximately 5 seconds. Afterward, the thermostat displays the measured temperature. It is normal that the displayed temperature be higher than the ambient temperature if you hold the thermostat in your hands. Once installed on the wall, the thermostat will display the ambient temperature. By default, the setpoint is 21°C (70°F) and the operating mode is set on manual. The time and day settings flash to indicate that they must be set (see section 5.1).

Completing the Installation

1. Once the baseplate and the batteries are installed, mount the thermostat on the baseplate.
2. Secure the thermostat using the locking screw and install the faceplate.
3. Apply power back to the system.

Basic Functions

System Operating Mode

Use this selector switch to set the system to heating mode (HEAT), cooling mode (COOL), or Off.
Note: When you place the thermostat in cooling mode, you might need to wait up to five minutes before cooling can start. This delay is a safety feature for the compressor. will flash on the screen until cooling can start again.

Fan Operating Mode

Use the selector switch to set the fan to automatic mode (AUTO) or continuous mode (ON).
Note: This switch is not used in a 2-wire installation as the fan is not connected to the thermostat.

AUTO	The fan operates only when heating or cooling is activated.
ON	The fan operates continuously.

Viewing and Setting the Temperature

The ambient temperature is normally displayed. To view the setpoint, press once on one of the buttons. The setpoint is displayed for 5 seconds and is indicated by the symbol on the display. During the setpoint display, press one of the buttons to change it.

Backlight
The display illuminates for 12 seconds when the backlight button or either of the buttons is pressed.

Thermostat Control Mode
Manual
The setpoint must be set manually. To place the thermostat in this mode, press [ Mode ]. The house icon will disappear.

Automatic
The setpoint varies according to the programmed schedule. To place the thermostat in this mode, press [ Mode ]. The current period settings will be displayed. The four possible periods are:

To see the default schedule settings, see section 5.3.

Unoccupied (TH148LE-P only)
To place the thermostat in unoccupied mode, see section 2.4. In this mode, the icon is displayed and only the buttons work to allow a temporary bypass.

Temporary Bypass
Automatic Mode
If you modify the setpoint (using the buttons) when the thermostat is in automatic mode, the thermostat temporarily bypasses the current program. The new setpoint will be maintained for 2 hours, then the thermostat will return to the program currently running in automatic mode. The house icon flashes during the bypass.

Unoccupied Mode (TH148LE-P only)
If you modify the setpoint (using the buttons) when the thermostat is in unoccupied mode, the thermostat temporarily bypasses the setpoint of the unoccupied mode. The new setpoint will be maintained for 2 hours, then the thermostat will return to the setpoint of the unoccupied mode. The icon…flashes during the bypass.

Filter Indicator

After 500 hours of operation, an icon appears to indicate that the filter needs replacement. Once the filter is replaced, press [ Filter ] for 3 seconds to remove the icon and reset the counter.

Battery Indicator

An icon appears when the batteries need replacement. This icon will flash for 120 days, then the thermostat will cut power to the heating/cooling unit. The icon disappears once the batteries are replaced and the thermostat is reinstalled on its base.

Warning: Before removing the batteries, place the system switch on the thermostat to Off. Otherwise, the heating/cooling unit might still be running even after the batteries are removed. After replacing the batteries, set the time and day (see section 5.1). For the TH148LE-P model, set the date also (see section 5.2).
Note: The temperature and schedule settings are not erased when the batteries are removed.
