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.

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.

.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.

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-

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.
