YOUR NEW THERMOSTAT’S FEATURES

• This thermostat incorporates easy one-finger operation.

• The thermostat has a liquid crystal display (LCD) that alternately displays time and temperature and shows system status. Celsius temperature display is optional.

• The thermostat has indicators for AM/PM mode, “setback on”, “cool on”, and “heat on”.

• The thermostat divides the time of day into 15-minute blocks, providing 48 possible setbacks over a 24hour period.

• To provide higher efficiency and better temperature control, and to help increase the life of your system,

this thermostat has automatic minimum cycle on and off timing.

• During power outages, the thermostat is powered by two standard

1.5V watch batteries. One set of batteries is included with your thermostat. Thermostat programming and clock operation are not affected by power outages when batteries are installed.

• The thermostat has a temperature differential switch for controlling temperature within either 1° F or 3°F of the set temperature.

• This thermostat controls heat/cool, heat-only, and electric heat systems.

• This thermostat is capable of meeting HUD requirements (may be field-disabled). This thermostat

CHECK YOUR THERMOSTAT’S LOCATION

also meets all state and federal energy efficiency requirements.

You should install your thermostat about five feet (1.5 meters) above the floor in an area with good air circulation and average temperature. Normally, you can simply replace your old thermostat with your new one.

However, you may consider changing the thermostat’s location if the thermostat is affected by:

• drafts or dead air spots behind doors and in corners.

• direct exposure to hot or cold air blowing from ducts.

• direct exposure to sunlight or heat from appliances.

• pipes or chimneys located behind the wall where the thermostat is located.

• unheated areas behind the thermostat, such as an outside wall.

OBSERVE THESE SAFETY PRECAUTIONS

WARNING

• DO NOT USE on circuits exceeding specified voltage -- higher voltage will damage thermostat, and may cause shock or fire hazard.

• DO NOT SHORT OUT TERMI- NALS on gas valve or primary control to test. Shorts or incorrect wiring will burn out heat anticipator, and may cause personal injury and/or property damage.

• DISCONNECT POWER at the main fuse or circuit breaker box before beginning thermostat removal/ installation. This will prevent electrical shock and/or damage to the heating/cooling system or thermostat.

CAUTION

• If in doubt about whether you wiring is millivolt, line, or low voltage, have it inspected by a qualified heating/air conditioning contractor.

• Do not exceed specification ratings (24 v AC -- 30v AC max., 1 amp.)

• Wiring must conform to local and national codes and ordinances.

• This thermostat is a precision instrument and should be handled carefully. Rough handling or distorting components could cause the thermostat to malfunction.

YOUR NEW THERMOSTAT’S COMPONENTS

Your thermostat consists of two parts: the base and the cover. To remove the cover, grasp it and pull it out from the base. Take a few minutes to become familiar with the location of switches and buttons on the thermostat. You will use them during installation and operation of your new thermostat. To replace the cover, align the cover with the base and push until it snaps into place. Do not force the cover onto the base, as this may damage the thermostat.

1. Disconnect 120v AC power.

2. Remove the cover from the old thermostat.

3. Remove terminal wires one at a time. As you remove each wire, tag the

wire with the terminal identification (such as Y, W, R) as shown on the old thermostat base.

4. When all wires are removed, remove the old thermostat base from the wall.

STOP!

If your system has five or six wires, read the following cautionary statements. If

your system has two or four wires, go directly to step 4.

CAUTION

NOTE

If you have a two-transformer (5-wire) system and both heat and cool transformer secondaries are grounded, you cannot use this thermostat, even if the transformers are properly phased.

Never connect the common (neutral) wire on the 24v AC side of the transformer to the thermostat.

For systems where neither or only one of the transformers is grounded, you may use this thermostat only if the transformers are properly phased. Use fig. 4 to wire the thermostat. If you are not sure of your particular application, contact a qualified service person or call the technical service number found elsewhere in this booklet.

4. Connect wires to the appropriate terminals on the base. See table 1 and figs. 2, 3, and 4 to match the tagged wires with the correct terminals.

5. When connections are complete, push excess wire back into the wall’s opening. Plug the opening with a fire-resistant insulating material, such as fiberglass insulation, to prevent drafts that could affect thermostat operation.

6. Attach the thermostat base to the wall using the two screws provided.

7. Check the wires on the thermostat base terminals; they should not be touching one another or any other part of the thermostat.

8. Set the option switches to desired positions (see SETTING OPTION SWITCHES).

9. Reconnect 120v AC power to system. The thermostat display should now be operating.

NOTE

If 120v AC power is to be disconnected immediately after thermostat installation, omit step 10 (to conserve battery power). Perform step 10 when power is restored to the system.

10. Pull battery insulation tab down firmly and remove. This will engage the batteries.

11. Replace the thermostat cover. Ensure that the system switch is in the Off position before you begin testing (see TESTING YOUR

THERMOSTAT).

SETTING OPTION SWITCHES

The 1°/3° DIFFERENTIAL SWITCH is

located to the right of the display on the base. The thermostat is preset at 1°F. At this setting, the thermostat will maintain the room temperature within 1°F of the set temperature (this results in more frequent system on/off cycles). If you move the switch to the left, the thermostat will maintain the room temperature within 3°F of the set temperature (resulting in longer on/off cycles). Normally, the 1°F setting is used.

The F°/C° SWITCH is located below the

display on the base. When you move the switch up, the temperature will be

displayed in degrees Fahrenheit. When you move the switch down, the temperature will be displayed in degrees Celsius.

The GAS/ELECTRIC SWITCH is located above the setback switch on the base. When you move the switch right, the fan will turn on immediately when the furnace turns on (for electric heaters). When you move the switch to the left, the fan will come on after the furnace warms up (for gas furnaces).
