NOTES

R & Rc terminals
In a single-transformer system, leave a metal jumper in place between R & Rc. Remove the metal jumper if a two-transformer system.

C terminal
The C (common wire) terminal is optional when the thermostat is powered by batteries.

W (O/B) terminal
If the thermostat is configured for a heat pump in the Installer Setup, configure the changeover valve for cool (“O” factory setting) or heat (“B”).

Wire specifications
Use 18- to 22-gauge thermostat wire. A shielded cable is not required.

1. Loosen screw terminals, insert wires into the terminal block, then re-tighten the screws.
2. Push excess wire back into the wall opening. Keep wires in the shaded area as shown on left.
3. Plug the wall opening with nonflammable insulation to prevent drafts from affecting thermostat operation.

Power options & mounting

AC Power

The thermostat can be powered by 24 VAC power, or by batteries. To wire the thermostat for AC power, connect the common side of the cooling transformer to the “C” terminal as shown at left.

Important
Remove R/Rc jumper for 2-transformer systems only. (See wiring diagram on page 5.)

Battery Power

The thermostat can be powered by batteries alone or, if used with AC power, can provide backup power. During power interruptions, the batteries will save time/day settings and power the display.
After installation, batteries can be changed without removing the thermostat from the wall (see page 11).

To Mount Thermostat
Align the 4 tabs on the wallplate with corresponding slots on the back of the thermostat, then push gently until the thermostat snaps in place.

Installer setup

Follow the procedure below to configure the thermostat to match the installed heating/cooling system, and customize feature operation as desired.

To begin, press and hold the FAN buttons until the display changes

• Press or to change settings
• Press NEXT to advance to the next function
• Press DONE to exit and save settings

Installer system test

Follow the procedure below to test the heating, cooling, and fan.

To begin, press and hold the buttons until the display changes.

• Press to turn on the system
• Press to turn off the system
• Press NEXT to advance to the next test
• Press DONE to terminate the system test

CAUTION
EQUIPMENT DAMAGE HAZARD
Compressor protection (minimum off time) is bypassed during testing. To prevent equipment damage, avoid cycling the compressor quickly.

Auto Changeover (Setup Function 12)

• Auto Changeover is a feature used in climates where both air conditioning and heating are used on the same day.When the system is set to Auto, the thermostat automatically selects heating or cooling depending on the indoor temperature.
• Heat and cool settings must be at least 3 degrees apart.The thermostat will automatically adjust settings to maintain this 3-degree separation (called “Deadband”).
• The 3-degree separation between heating and cooling set temperatures is fixed, and cannot be changed.

Adaptive Intelligent Recovery™ (Setup Function 13)

• Adaptive Intelligent Recovery eliminates guesswork when setting your schedule. It allows the thermostat to “learn” how long your furnace and air conditioner take to reach the temperature you want.
• Just set your program schedule to the time you want the house to reach your desired temperature.The thermostat then turns on the heating or cooling at just the right time to reach your scheduled temperature at your scheduled time.

For example
Set the Wake time to 6 am, and the temperature to 70°.The heat will come on before 6 am, so the temperature is 70° by the time you wake at 6.

Built-in compressor protection (Setup Function 15)

• This feature helps prevent damage to the compressor in your air conditioning or heat pump system.
• Damage can occur if the compressor is restarted too soon after shutdown.This feature forces the compressor to wait for a few minutes before restarting.
• During the wait time, the message Cool On or Heat On (heat pumps only) will flash on the display. When the safe wait time has elapsed, the message stops flashing and the compressor turns on.
