IMPORTANT SAFETY INFORMATION WARNING

1. Always turn off power at the main power source by unscrewing fuse or switching circuit breaker to the off position before installing, removing, cleaning, or servicing thermostat.
2. Read all of the information in this manual before installing or programming this thermostat.
3. This is a 24V AC low voltage thermostat. Do not install on voltages higher than 30V AC.
4. All wiring must conform to local and national building and electrical codes and ordinances.
5. 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 thermostat on an inside wall, 4-5 feet above the floor. Do not install the thermostat in the following locations:

1. Behind a Door
2. In a Corner
3. Near Air Vents
4. In Direct Sunlight
5. With an Outside Wall Behind the Thermostat
6. Near any Heat or Steam Generating Fixtures
7. Near any Concealed Pipes or Chimneys
   Installation at these locations will affect thermostat operation.

WALLPLATE INSTALLATION

Caution:
Electrical Hazard
Disconnect power before installing this product. Failure to do so can cause electric shock or equipment damage.

For a vertical mount, put screws on the top and bottom. For a horizontal mount, put screws on the left and the right.

Mercury Notice:
This product is mercury-free. However, if this product is replacing a control that contains mercury, it needs to be disposed of properly. Contact your local waste management authority for instructions regarding recycling and proper disposal of the control.

WIRING

1. Turn Off Power to the Heating/Cooling System
   
2. Remove Old Thermostat
   Remove old thermostat but leave wallplate with wires attached.
   
3. Label Wires with Tags
   Label the wires using the supplied wire labels as you disconnect them.
   
4. Separate Wallplate from New Thermostat
   Remove wallplate from the new thermostat and mount onto wall.
   
5. Mount Wallplate for 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 letters on the thermostat, check “Alternate Wiring (Conventional Systems)” on page 9 and connect to terminal as shown (see notes, below).

Alternate Wiring (Conventional Systems)

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

1. If wires will be connected to both RC and RH/R terminals, remove metal jumper.
2. If C or X wire is available then you can connect with C terminal. If there is no C or X wire then no need to connect with C terminal.
3. 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 bare end of wire with electrical tape.
   Place a jumper (piece of wire) between Y and W if you are using a heat pump without auxiliary/backup heat.

Terminal Designations

• C 24 VAC Common Wire
• O Heat pump reversing valve energized in cooling
• B Heat pump reversing valve energized in heating
• W Heat relay
• RH 24 VAC power for heating
• RC 24 VAC power for cooling
• G Fan relay
• Y Compressor relay

Wiring Notes

• RH & RC Terminals
  In a single-transformer system, leave the metal jumper in place between the RH and RC. Remove the metal jumper in two-transformer systems.
• Heat Pump Systems (With NO Auxilary or Emergency Heat)
  If wiring to a heat pump, use a small piece of wire (not supplied) to connect terminals W (Heat relay) & Y (Compressor relay).
• Common wire
  The C (common wire) is optional when the thermostat is powered by batteries.
• Wire Specifications
  Use 18- to 22-gauge thermostat wire. Shielded wire is not required.
  Installation Tip: Do not overtighten terminal block screws, as this can damage the terminal block. A damaged terminal block can keep the thermostat from fitting on the subbase correctly or cause system operation issues. Max Torque = 6in/lbs.

1. Power supply.
2. Factory-installed jumper. Remove only when installing on 2-transformer systems.
3. Use either O or B terminals for reversing valve.
4. Use a small piece of wire (not supplied) to connect W and Y terminals.
5. Set fan operation switch to electric.
6. Optional 24 VAC common connection when thermostat is used in battery power mode.
