• Hardwire (Common Wire)

IMPORTANT SAFETY INFORMATION WARNING

• Always turn off power at the main power source by unscrewing the fuse or switching the circuit breaker to the off position before installing, removing, cleaning, or servicing the thermostat.
• Read all of the information in this manual before installing or programming this thermostat.
• This is a 24V AC low-voltage thermostat. Do not install on voltages higher than 30V AC.
• All wiring must conform to local and national building and electrical codes and ordinances.
• Do not short (jumper) across terminals on the gas valve or at the system control to test installation. This will damage the thermostat and void the warranty.

INSTALLATION LOCATION

Install the thermostat 4 to 5 feet above the floor in an area with good air circulation and average temperature.

For new installations, mount the thermostat on an inside wall, 4-5 feet above the floor. Do not install the thermostat in the following locations:

• Behind a Door
• In a Corner
• Near Air Vents
• In Direct Sunlight
• With an Outside Wall Behind the Thermostat
• Near any Heat or Steam Generating Fixtures
• Near any Concealed Pipes or Chimneys

4. Separate Wallplate from New Thermostat
   Remove the wallplate from the new thermostat and mount it onto the wall.

5. Separate Wallplate from New Thermostat
   Mount the new wallplate using the included screws and anchors.

   • Drill 3/16-in. holes for drywall
   • Drill 3/16-in. holes for plaster

6. Connect Wires
   Simply match wire labels.
   If labels do not match the letters on the thermostat, check “Alternate Wiring (Conventional Systems)” on page 9 and connect to the terminal as shown (see notes, below).

Alternate Wiring (Conventional Systems)

If labels do not match the letters on the thermostat, check the chart below and connect to the terminal as shown here (See notes, below).

1. If C or X wire is available then you can connect with the C terminal. If there is no C or X wire then no need to connect with the C terminal.
2. If you have a heat pump without auxiliary/backup heat connect O or B, not both. If you do not have a heat pump, do not connect B. Wrap the bare end of the wire with electrical tape.
3. Place a jumper (a piece of wire) between Y and W if you are using a heat pump without auxiliary/backup heat.
