n Remove the old thermostat to access the wires.

The TH147-P and TH148LE-P programmable thermostats can be

used to control:

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.

•

a gas, fuel oil or electric furnace - 2 or 3 wires

a central air conditioner - 2 or 3 wires

o Identify and label each wire (with the corresponding letter on

a hot water system with or without pump - 2 wires

a millivolt system - 2 wires

the wire terminal) and remove them from the terminals.

p If necessary, strip the end of each wire

a central heating and cooling system - 4 or 5 wires

(

maximum of 6 mm).

Attention: These thermostats are not compatible with heat pumps

or multi-stage systems.

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.

2.4 Remote Control Input (TH148LE-P only)

The TH148LE-P thermostat has an input to which a CT240 tele-

phone 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.

p 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.

.5 Thermostat Control Mode

.5.1 Manual

The setpoint must be set manually. To place the thermostat in this

mode, press [ Mode ]. The house icon will disappear.

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.

.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:

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 dis-

appears once the batteries are replaced and the ther-

mostat 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 The fan operates only when heating or cooling is activated.

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.

The fan operates continuously.
