INSTALLATION

REMOVE OLD THERMOSTAT

1. Shut off electricity at the main fuse box until installation is complete. Ensure that electrical power is disconnected.
2. Remove the front cover of the old thermostat. With wires still attached, remove wall plate from the wall. If the old thermostat has a wall mounting plate, remove the thermostat and the wall mounting plate as an assembly.
3. Identify each wire attached to the old thermostat using the labels enclosed with the new thermostat.
4. Disconnect the wires from old thermostat one at a time. DO NOT LET WIRES FALL BACK INTO THE WALL.
5. Install new thermostat using the following procedures.

ELECTRIC HEAT OR SINGLE-STAGE HEAT PUMP SYSTEMS
Read entire paragraph before setting electric heat switch. If you are unsure of your application, contact a qualified serviceperson.
If you have a single-stage heat pump system, OR your system uses central electric heat, where the blower is energized by a separate circuit through the fan relay (meaning that the fan turns on immediately on call for heat), then the switch on the back of the thermostat base must be moved to the “ELECTRIC” position (see fig. 1). If the thermostat is energizing electric heat sequencers, the switch MUST remain in the “GAS” position.
If you must move the switch to the “ELECTRIC” position (to the left), use a small screwdriver or pencil.

ATTACH THERMOSTAT BASE TO WALL

1. Remove the packing material from the thermostat. Gently pull the cover straight off the base. Forcing or prying on the thermostat will cause damage to the unit. If necessary, move the electric heat switch (see ELECTRIC HEAT SYSTEMS, above).
2. Connect wires beneath terminal screws on base using appropriate wiring schematic (see figs. 3 through 10).
3. Place base over hole in wall and mark mounting hole locations on wall using base as a template.
4. Move base out of the way. Drill mounting holes.
5. Fasten base loosely to wall, as shown in fig. 2, using two mounting screws. Place a level against bottom of base, adjust until level, and then tighten screws. (Leveling is for appearance only and will not affect thermostat operation.) If you are using existing mounting holes, or if holes drilled are too large and do not allow you to tighten base snugly, use plastic screw anchors to secure subbase.
6. Push excess wire into wall and plug hole with a fire-resistant material (such as fiberglass insulation) to prevent drafts from affecting thermostat operation.

BATTERY LOCATION

This thermostat requires 3 “AA” alkaline batteries to operate. Batteries are installed in the thermostat at the factory with a battery tag to prevent power drainage. You must remove the battery tag to engage the batteries and provide power to the thermostat.
If the word BATTERY is displayed, the batteries are low and should be replaced with fresh “AA” Energizer® alkaline batteries. To replace batteries, install the batteries along the top of the base (see fig. 2). The batteries must be installed with the positive (+) ends to the left.

CHECK THERMOSTAT OPERATION

If at any time during testing your system does not operate properly, contact a qualified serviceperson.

Fan Operation
If your system does not have a G terminal connection, skip to Heating System.

1. Turn on power to the system.
2. Move FAN switch to ON position. The blower should begin to operate.
3. Move FAN switch to AUTO position. The blower should stop immediately.

Heating System

1. Move SYSTEM switch to HEAT position. If the heating system has a standing pilot, be sure to light it.
2. Press to adjust thermostat setting above room temperature. The heating system should begin to operate.
3. Press to adjust temperature setting below room temperature. The heating system should stop operating.

Cooling System
This thermostat has a built-in short-term (5-minute) time delay. This feature is activated after the compressor shuts down and the setpoint is changed within the 5-minute period. During this minute period, COOL will flash on the display indicating that the thermostat has locked out the compressor to allow head pressure to stabilize. This thermostat does not sense AC power loss and therefore does not activate the short term compressor protection feature when power is restored.

CAUTION To prevent compressor and/or property damage, if the outdoor temperature is below 50°F, DO NOT operate the cooling system.

1. Move SYSTEM switch to COOL position.
2. Pressto adjust thermostat setting below room tempera-ture. The blower should come on immediately on high speed, followed by cold air circulation
3. Press to adjust temperature setting above room tempera-ture. The cooling system should stop operating.

OPERATION

Before you begin using your thermostat, you should be familiar with its features and with the display and the location and operation of the thermostat buttons. Your thermostat consists of two parts: the thermostat cover and the base. To remove the cover, gently pull it straight out from the base. To replace the cover, line up the cover with the base and press gently until the cover snaps onto the base.

THE THERMOSTAT BASE

The Thermostat Buttons and Switches
Other thanand, the following buttons and switches are located behind the door on the bottom of the thermostat cover (see fig. 11). Pull the door down to open it.

1. (Red arrow) Raises temperature setting.
2. (Blue arrow) Lowers temperature setting.
3. FAN switch (ON, AUTO).
4. SYSTEM switch (COOL, OFF, HEAT).
   The Display
5. HEAT is displayed when the SYSTEM switch is in the HEAT position. COOL is displayed (non-flashing) when the SYSTEM switch is in the COOL position. COOL is dis-played (flashing) when the compressor is in lockout mode. OFF is displayed when the SYSTEM switch is in the OFF position.
6. Displays current temperature.
7. BATTERY is displayed when the 3 “AA” batteries are low and should be replaced. Nothing else will be displayed.
8. Displays current setpoint temperature (this is blank when SYSTEM switch is in the OFF position).

OPERATING FEATURES

Now that you are familiar with the thermostat buttons and display, read the following information to learn about the fea-tures of the thermostat.

• SIMULTANEOUS HEATING/COOLING STORAGE — You can enter both your heating and cooling setpoints at the same time. There is no need to reset the thermostat at the beginning of each season.
• LOW BATTERY INDICATOR — If the 3 “AA” alkaline batteries are low and should be replaced, the display will be blank except for the word BATTERY. When the batteries are low, pressing any button will cause the display to operate for ten seconds. After ten seconds, the display will be blank except for the word BATTERY. When the duration of a low battery condition exceeds four weeks, the setpoint is altered by 10 degrees to signal that the batteries must be replaced.
• °F/°C CONVERTIBILITY— After ten seconds of no key activity, when the thermostat is in the temperature display adjustment mode, or 30 seconds after power up, pressing andat the same time will switch the LCD temperature display between Fahrenheit and Celsius.
• TEMPERATURE DISPLAY ADJUSTMENT — Your new thermostat has been accurately set in our factory. However, if you wish, you may adjust your new thermostat tempera-ture display to match your old thermostat. This can be accomplished (within a ±4° range) as follows:
  1. Press and at the same time within 30 seconds of applying power.
  2. Press or to adjust the displayed temperature to your desired setting.
  3. After setting your desired temperature, do not press any buttons for ten seconds. The thermostat will continue operating at the changed temperature setting.

SETTING THE THERMOSTAT

This thermostat is very easy to operate. Set the SYSTEM button to either HEAT or COOL, then press or until the temperature you want to maintain is shown on the right side of the display. If you want to turn the system off, just move the SYSTEM switch to OFF.
The FAN switch controls the fan operation. When the FAN switch is set to AUTO, the fan will cycle with the furnace or air conditioner. When the FAN switch is set to ON, the fan will run continuously, regardless of SYSTEM switch position.
