.
Introduction  
The TH149 thermostat is used for the following systems:  
n
Heat pump (1H1C and 2H1C)  
HVAC (1H1C)  
p
q
If necessary, bore the mounting holes  
and insert anchors.  
The thermostat incorporates the following functions:  
System mode selection: heat, cool, auxiliary heat and off  
Fan mode selection: automatic or on (continuous)  
Emergency heat and fault LEDs  
Activation indicators (heat, cool, and auxiliary heat)  
Temperature display in °C or °F  
Backlit display  
Programmable heating and cooling cycle lengths  
Keypad lock  
Pass the wires through the opening of  
the back plate and fix the plate to the  
wall using the screws provided.  
2.3 Connecting the Thermostat  
The connection of the new thermostat should be similar to that of the old ther-  
mostat; however, it can vary depending on the installation.

Installation  
Note: The installation must be performed by a qualified electrician.  
2.4 Jumper settings  
o
The jumpers (JP1 and JP2), on the back of the front module, are used to con-  
figure the thermostat according to your system type:

Remove the old thermostat to access the wires.  
Identify and label each wire (with the corresponding letter on the old ther-  
mostat terminals) and remove them from the terminals.

If necessary, strip the end of each wire (maximum of 6 mm).  
If necessary, wrap the wires around a pencil to pre-  
vent them from falling into the wall cavity.  
2.5 Completing the Installation  
n
Reinstall the front module onto the back plate and tighten the locking  
screw.  
r
If the opening in the wall is too big, insulate it using  
a non-flammable material to avoid air draughts  
behind the thermostat.  
o Place the system mode selector switch to OFF.  
Note: Leave the switch to OFF until you have verified that the thermostat is  
properly configured (see section 3).

.2 Installing the Back Plate  
Note: 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.) or dead air spots (behind doors). Do not install the thermostat  
on a wall concealing air ducts nor expose it to direct sunlight.  
p
q
Apply power back to the system.  
Ensure that the thermostat is configured according to your system type  
(
see section 3).

Note: Emergency heat mode is not available on 1H1C systems.  
For these systems, placing the selector on E.H. is the same as  
placing it on Off.  
Auxiliary Heat  
Only 2H1C systems are equipped with auxiliary heat. The auxiliary heat is  
used in the following conditions:  
When the setpoint is not attained after a 15-minute delay following the  
compressor activation. After the delay, the auxiliary heating is used along  
with the compressor.  
When the thermostat is placed in emergency heating (E.H.). In this mode,  
only the auxiliary heat is used.

.2 Fan Mode  
Use the fan mode selector switch to place the fan in automatic  
mode (AUTO) or continuous mode (ON).  
This warranty gives you specific legal rights, and you may have other rights which  
vary by province, state or region.
