Installation should be carried out by an electrician or a qualified  
technician.  
1.1  
Find a Location for the Thermostat  
•
For a new installation, choose a location about 5 ft. (1.5 m) above  
the floor and on an inside wall.  
Loosen the captive screw  
holding the base to the  
module.  
Gently lift the lower part of  
the module to remove it  
from the base.  
Secure the base using the  
wall anchors & screws.  
Wire the thermostat.  
•
Avoid locations where there are air drafts (top of staircase, air out-  
let), dead air spots (behind a door), direct sunlight, concealed  
chimneys or pipes, or air diffusers.

1.5  
First Power On  
To remotely activate the Unoccupied mode, the REM input allows  
connection to an optional CT240/CT241 telephone controller, a  
central timer or an alarm system.  
When you power TH144 for the first time, it  
runs a sequence of tests and resets itself,  
which lasts approximately 10 seconds. The  
default setpoint is 20°C (68°F).  
A closed contact remotely activates the Unoccupied mode (see 4.1).  
NOTE: The displayed ambient temperature  
might be higher than the real ambient temper-  
ature if you are holding the thermostat.

For the programmable models, open the thermostat’s door, and set  
the time (Hour and Minute) and day (Day).  
NOTE: Before you configure the TH144, make sure the thermostat  
sits on the base for at least 5 minutes.  
NOTE: To protect the compressor, TH144 has an On/Off delay of 2  
or 4 minutes (default is 2 minutes) before starting or stopping the  
system (see switch #4 in following section).

NOTE: After first power-up, wait at least 5 minutes while the internal  
battery is being charged before configuring TH144.
