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.

ATTACH THERMOSTAT BASE TO WALL

1. Remove the packing material from the thermostat.

2. If necessary, cut the non-electric heat jumper (see NON-

ELECTRIC HEAT SYSTEMS) and/or the EMR jumper (see ENERGY MANAGEMENT RECOVERY). Check the set- ting of the O/B switch (see O/B TERMINAL SWITCH SELECTION).

3. If you want to program the thermostat before mounting the thermostat on the wall, see ARMCHAIR PROGRAMMING.

4. Gently pull the thermostat cover straight off the base. Forcing or prying on the thermostat will cause damage to the unit.

5. Check that the SYSTEM switch is in the OFF position. Connect wires beneath terminal screws on base using appropriate wiring schematic (see figs. 3 through 5).

6. Place base over hole in wall and mark mounting hole locations on wall using base as a template.

7. Move base out of the way. Drill mounting holes.

8. 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.

9. Push excess wire into wall and plug hole with a fire-resistant material (such as fiberglass insulation) to prevent drafts from affecting thermostat operation.

NON-ELECTRIC HEAT SYSTEMS

Read the following information before clipping the non-electric heat jumper. If you are unsure of your application, contact a qualified serviceperson.

If your emergency or auxiliary system is non-electric (gas, oil, etc.) and will energize the blower, then jumper, W904, on the back of the thermostat base must be cut (see fig. 1).

If your emergency or auxiliary heat system is electric and requires that the thermostat energize the fan circuit, do not cut jumper W904.

ENERGY MANAGEMENT RECOVERY

When the EMR feature is activated, the thermostat's microcomputer automatically calculates the time it will take to change the room temperature to the next program setting. Then the thermostat will start the heating or cooling system before the next

programmed period so that the desired temperature is reached at or near the beginning of the next program period (the thermostat calculates 30 minutes for every 2°F temperature change).

For example, assume that the thermostat is programmed to provide an overnight heating temperature of 66°F, and during the next program period, beginning at 6:00 AM, the programmed temperature is 70°F. With EMR activated, the thermostat will automatically start the heating system at 5:00 AM, so that the programmed temperature of 70°F is reached by about 6:00 AM.

If the overnight room temperature drops only to 68°, the thermostat will start the system at 5:30 to reach the programmed temperature of 70° at 6:00.

The thermostat is shipped with the EMR feature active, which

(EMR)

means that the thermostat will start the system before the beginning of the next program period. This feature provides better efficiency by allowing gradual temperature changes using only the first stage of heat and cooling.

To de-activate the EMR function, clip wire W903 on the back of the thermostat (see fig. 1). The thermostat will then wait until the programmed time to start the system for a temperature change. This may cause the more costly electric second stage of heating to be used.

O/B TERMINAL SWITCH SELECTION

The O/B switch on this thermostat is factory set to the “O” position. This will accommodate the majority of heat pump applications, which require the changeover relay to be energized in COOL. If the thermostat you are replacing or the heat pump being installed with this thermostat require the “B” terminal, to energize the changeover relay in HEAT, the O/B switch must be moved to the “B” position.

ARMCHAIR PROGRAMMING

Armchair Programming is a unique feature that allows your thermostat to be programmed before being mounted on the wall. If you do not want to Armchair Program, the thermostat can be programmed after being mounted on the wall and system power turned on.

If you wish to Armchair Program your thermostat, temporarily hold a new 9-volt battery against the wires in the battery cutout on the back of the thermostat base for approximately 45 seconds. This will provide a charge that will last approximately 30 to 45 minutes to allow the thermostat to be programmed. After programming, the thermostat must be mounted on the wall, wires connected and system power turned on.

Heating System

1. Move SYSTEM switch to HEAT position. If the auxiliary heating system has a standing pilot, be sure to light it.

2. Press to adjust thermostat setting to 90° and hold for five seconds. Both stages of the heating system should begin to

operate. However, if the word HEAT is flashing, the compressor lockout feature is operating (see Lockout Bypass Option to temporarily override the compressor lockout feature during testing).

3. Press to adjust temperature setting below room temperature. The auxiliary heating system will stop immedi-

ately, and the first stage will stop within three to four minutes.

Cooling System

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.

NOTE

To have sufficient time to complete the installation without losing the programming, hold the 9-volt battery to the terminals on the back of the base for 30 to 45 seconds again after programming the thermostat. The battery must be removed before mounting the thermostat on the wall.

ADJUSTABLE ANTICIPATION

The first stage has anticipation that can be set to 2.5 or 4 cycles per hour for heating or cooling. The second stage heat has a fixed anticipation. To change the first stage anticipation in the HEAT or COOL mode, press SET TIME and VIEW PRGM buttons at the same time until the desired setting is displayed (S for slow (factory setting) or F for fast).

CHECK THERMOSTAT OPERATION

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

Fan Operation

1. Turn on power to the system.

2. Move SYSTEM switch to OFF position.

3. Move FAN switch to ON. The blower should begin to operate.

4. Move FAN switch to AUTO position. The blower should stop within a short period of time.

2. Press to adjust thermostat setting below room temperature. The blower should come on immediately on high speed,

followed by cold air circulation. However, if the fan is running but the compressor is not running and the word COOL is flashing, the compressor lockout feature is operating (see Lockout Bypass Option to temporarily override the compressor lockout feature during testing).

3. Press perature. The cooling system should stop operating.

gram to the factory setting. This button can be used if you do not like the program you have entered or if you wish to start over in the programming procedure. The reset button can also be used to reset the program if the thermostat has been subjected to a voltage spike and the program has become scrambled or frozen.

example, heating/cooling period 1 on Monday may begin at 5:00 AM, but heating/cooling period 1 on Saturday may begin at 9:00 AM). Use the table on the following page to plan your program time periods, and the temperatures you want during each period. You may also want to look at the sample program table to get an idea of how the thermostat can be programmed.

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.

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.

* You may only program heating temperatures you have selected into the heating

program and cooling temperatures into the cooling program (for example, you cannot program the COOL 1 temperature into your heating program). You may program the temperatures you choose in any order, and you may use the same temperature in consecutive program periods (for example, you may program period 1 with temperature 1 and periods 2, 3, and 4 with temperature 2). You do not have to use all possible temperature choices (for example, you may want to select temperatures for HEAT 1 and HEAT 2 only – in this case, the HEAT 3 and HEAT 4 temperatures would stay the same as previously programmed).

2. Determine the time periods during which you will program the temperatures you have just selected. You must program four periods for each day (periods 1, 2, 3, and 4). However, you may use the same heating and cooling temperatures for consecutive time periods. Also keep in mind that, for any given day, you can only program one set of times for both heating and cooling (for example, if you select 5:00 AM to begin heating period 1 on Monday, then your cooling period 1 for Monday will also begin at 5:00 AM). However, you may select different time periods for each day separately (for
