Installation
and User Guide
2. Installation
Note: The installation must be performed by an electrician or a qualified installer.
2.1 Removing the Old Thermostat
IN ORDER TO AVOID ANY RISK OF ELECTRIC SHOCK, CUT
POWER TO THE HEATING/COOLING SYSTEM.
1. Introduction
The TH147-P and TH148LE-P programmable thermostats can be
used to control:
• a gas, fuel oil or electric furnace - 2 or 3 wires
• a central air conditioner - 2 or 3 wires
n
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.
o
Identify and label each wire (with the corresponding letter on
the wire terminal) and remove them from the terminals.
• a central heating and cooling system - 4 or 5 wires
p
Attention: These thermostats are not compatible with heat pumps
or multi-stage systems.
If necessary, strip the end of each wire
(maximum of 6 mm).
q
Wrap the wires around a pencil to prevent
them from falling into the wall.
r
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.
• a hot water system with or without pump - 2 wires
• a millivolt system - 2 wires

2.2 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 staircase, air outlet, etc), dead air spots (behind
doors), direct sunlight or areas near concealed pipes or chimneys.

2.3.1 2-wire Heating
2.4 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.
Heat relay
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.

2.6 Installing the Batteries
3.3 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.
3.4 Backlight
n
o
p
Gently pull out the battery cover.
Install the batteries as shown. Observe the polarity.
Reinstall the battery cover. You will hear a clicking sound.
After the batteries are installed, the thermostat performs a
sequence of tests for approximately 5 seconds.
Afterwards, 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).
2.7 Completing the Installation
The display illuminates for 12 seconds when the backlight button or
either of the
buttons is pressed.
3.5 Thermostat Control Mode
3.5.1 Manual
The setpoint must be set manually. To place the thermostat in this
mode, press [ Mode ]. The house icon will disappear.
3.5.2 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:
Wake up
Leave for work
Return home
Sleep
To see the default schedule settings, see section 5.3.
3.5.3 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.
3.6 Temporary Bypass
3.6.1 Automatic Mode
n
Once the baseplate and the batteries are installed, mount the
thermostat on the baseplate.
o
Secure the thermostat using the locking screw and install the
faceplate.
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.
p
Apply power back to the system.
3.6.2 Unoccupied Mode (TH148LE-P only)
3. Basic Functions
3.1 System Operating Mode
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.
Use this selector switch to set the system to heating
mode (HEAT), cooling mode (COOL), or Off.
3.7 Filter Indicator
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.
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.
3.2 Fan Operating Mode
3.8 Battery Indicator
Use the selector switch to set the fan to automatic
mode (AUTO) or continuous mode (ON).
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 reinstalled on its base.
Note: This switch is not used in a 2-wire installation as
the fan is not connected to the thermostat.
AUTO
ON
The fan operates only when heating or cooling is activated.
The fan operates continuously.
TH147-P and TH148LE-P
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.
