The TH149 thermostat is used for the following systems:
The thermostat incorporates the following functions:
Note: Auxiliary heat is available only for 2H1C systems.
Note: The installation must be performed by a qualified electrician.
Removing the Old Thermostat
IN ORDER TO AVOID ANY RISK OF ELECTRIC SHOCK, CUT POWER TO THE HEATING SYSTEM.
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.
Connecting the Thermostat
The connection of the new thermostat should be similar to that of the old thermostat; however, it can vary depending on the installation.
R; C | Power; 24 VAC |
W | Heater. This connection is not required for HP-1H1C. |
Y | Compressor |
G | Fan |
O/B | Reversing valve (see section 2.4). This connection is not required for HVAC-1H1C. |
L | Fault |
The jumpers (JP1 and JP2), on the back of the front module, are used to con-figure the thermostat according to your system type:
Jumper | Parameter | Settings |
JP1 | System | • Heat pump (HP position – default) • HVAC (CN position) |
JP2 | Reversing valve | • Activated in cool mode (O position – default) • Activated in heat mode (B position) |
Completing the Installation
The configuration parameters appear in the order shown below.
PARAMETERS | DEFAULT | OPTIONS |
Temperature display | °C | °C or °F |
Heating cycles per hour 1 | 4 | 2, 3, 4, 5 or 6 2 |
Cooling cycles per hour 1 | 4 | 2, 3, 4, 5 or 6 2 |
System type | 2H | 2H (2H1C) or 1H (1H1C) |
1H1C type 3 | HP | HP (Heat Pump) or Cn (HVAC) |
1 When either the heating or the cooling parameter is displayed, use the mode selector switch to toggle between the two parameters. 2 The corresponding cycle lengths are: 2 = 30 min., 3 = 20 min., 4 = 15 min., 5 = 12 min., 6 = 10 min. 3 This parameter appears only if you select 1H1C for the system type. |
System Mode
Use the system mode selector switch to place the system in heat mode, cool mode, emergency heat (E.H.) mode, or off.
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:
Fan Mode
Use the fan mode selector switch to place the fan in automatic mode (AUTO) or continuous mode (ON).
Note: This switch is not functional if the fan is not connected to the thermostat.
AUTO | The fan operates only when heating or cooling is activated. |
ON | The fan operates continuously. |
Viewing and Setting the Temperature
The actual temperature is normally displayed. To view the setpoint, press once on one of the temperature adjustment buttons. The setpoint is displayed
for 5 seconds and is indicated by the
Backlight
The display illuminates for 12 seconds when either of the temperature adjustment buttons is pressed.
A switch on the back of the front module can be used to lock the setpoint.
