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 the 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.

HEATING SYSTEMS
This thermostat is set to operate properly if you have a forced­air heating system. If you have a hydronic heating system (a system that heats with hot water or steam), you must set the thermostat to operate properly with your system. While in the HEAT mode, change the setting by pressing and holding SET TIME and VIEW PRGM buttons at the same time until the correct setting is displayed (A for forced air; H for hydronic systems). If there is a loss of battery power, or when you change batteries, you must repeat this operation once battery power is restored.
NOTE
If you do not press both buttons at the same time, A or H will not be displayed. If this happens, press RUN PRGM, then press and hold SET TIME and VIEW PRGM at the same time.

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 5-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.
Before you begin programming 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.
1. Move SYSTEM switch to COOL position.
2. Press
to 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 tem-
perature. The cooling system should stop operating.

OPERATING FEATURES
Now that you are familiar with the thermostat buttons and display, read the following information to learn about the many features of the thermostat.
SIMULTANEOUS HEATING/COOLING PROGRAM STORAGE — When programming, you can enter both your heating and cooling programs at the same time. There is no need to reprogram the thermostat at the beginning of each season.
TEMPERATURE OVERRIDE — Press display shows the temperature you want. The thermostat
will override current programming and keep the room temperature at the selected temperature until the next program period begins. Then the thermostat will automati­cally revert to the program.
HOLD TEMPERATURE — The thermostat can hold any temperature within its range for an indefinite period, without reverting to the programmed temperature. Press HOLD TEMP button. HOLD will be displayed. Then choose the
desired hold temperature by pressing thermostat will hold the room temperature at the selected
setting until you press RUN PRGM button to start program operation again.
°F/°C CONVERTIBILITY — Press and hold SET TIME and HOLD TEMP buttons until the temperature display is in Celsius (°C). To display Fahrenheit (°F), repeat the pro- cess.
12-HOUR/24-HOUR CLOCK DISPLAY — The clock is set to display 12-hour time, which means that the clock will display AM and PM time (12:00 AM is midnight; 12:00 PM is noon). However, you may want to display a 24-hour clock (military-style time). The 24-hour clock display will show 1:00 PM as 13:00, 2:00 PM as 14:00, and so on. To change to the 24-hour clock display, press and hold SET TIME and RUN PRGM buttons at the same time. In the 24-hour clock mode, AM and PM are not displayed.
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. You cannot program with low batteries, but you can override setpoint temperature.
or until the
or . The
TEMPERATURE DISPLAY ADJUSTMENT — Your new thermostat has been accurately set in our factory. However, if you wish, you may adjust your new thermostat tempera­ture display to match your old thermostat. This can be accomplished (within a ±4° range) as follows:
1. Press VIEW PRGM and HOLD TEMP buttons at the
same time.
2. Press
or to adjust the displayed temperature to
your desired setting.
3. Press RUN PRGM to resume normal program operation.
PROGRAMMING YOUR THERMOSTAT
Now you are ready to program your thermostat. This section will help you plan your thermostat’s program to meet your needs. For maximum comfort and efficiency, keep the following guide­lines in mind when planning your program.
• When heating (cooling) your building, program the tem­peratures to be cooler (warmer) when the building is vacant or during periods of low activity.
• During early morning hours, the need for cooling is usually minimal.
• Program the thermostat to allow about 30 minutes to reach the desired temperature. (For example, if the first person gets up at 6:00 AM, program the first period to begin at 5:30 AM.)
Look at the factory preprogrammed times and temperatures shown below. If this program will suit your needs, simply press the RUN PRGM button to begin running the factory preset program.
