FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL INJURY AND/OR PROPERTY DAMAGE.

DESCRIPTION

This wall-mounted, low voltage thermostat maintains room temperature by controlling the operation of heating and cooling systems. The user may program up to four time/temperature settings per 24 hour period. The thermostat stores independent heating and cooling programs for each day of the week. The thermostat will store both heating and cooling programs simultaneously. Three “AA” Energizer® batteries will maintain the stored program for approximately one year, if incoming power should fail. If power failure is extensive and the program is lost, after power restoration, the thermostat will automatically maintain a factory preprogrammed heating temperature of 64°F or a cooling temperature of 82°F.

If in doubt about whether your wiring is millivolt, line, or low voltage, have it inspected by a qualified heating and air conditioning contractor, electrician, or someone familiar with basic electricity and wiring.

Do not exceed the specification ratings.

PRECAUTIONS

All wiring must conform to local and national electrical codes and ordinances.

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

! CAUTION

To prevent electrical shock and/or equipment damage, disconnect electric power to system, at main fuse or circuit breaker box, until installation is complete.

!WARNING

Do not use on circuits exceeding specified voltage. Higher voltage will damage control and could cause shock or fire hazard.

Do not short out terminals on gas valve or primary control to test. Short or incorrect wiring will burn out thermostat and could cause personal injury and/or property damage.

INSTALLATION

NEW INSTALLATION

You should program the thermostat with batteries installed before attaching on subbase. See OPERATION GUIDE for programming instructions.

SELECT THERMOSTAT LOCATION

Proper location insures that the thermostat will provide a comfortable building temperature. Observe the following general rules when selecting a location:

1.Locate thermostat about 5 ft. above the floor.

2.Install thermostat on a partitioning wall, not on an outside wall.

3.Never expose thermostat to direct light from lamps, sun, fireplaces or any temperature radiating equipment.

4.Avoid locations close to windows, adjoining outside walls, or doors that lead outside.

5.Avoid locations close to air registers or in the direct path of air from them.

6.Make sure there are no pipes or duct work in that part of the wall chosen for the thermostat location.

7.Never locate thermostat in a room that normally warmer or cooler than the rest of the building.

8.Avoid locations with poor air circulation, such as behind doors or in alcoves.

ROUTE WIRES TO LOCATION

NOTE

All wiring must conform with local and national electrical codes and ordinances.

1.Probe for obstructions in partition before drilling 1⁄2” hole in wall at selected location. Take up quarter round and drill a small guide hole for sighting (see fig. 1). From basement, drill 3⁄4” hole in partition floor next to guide hole. In buildings without basements, drill 1⁄2” hole through ceiling and into partition from above.

2.Through this hole drop a light chain, or 6” chain attached to a strong cord. Snag cord in basement with hooked wire. In buildings without basements, drop cord through hole in ceiling and down partitioning; snag cord at the thermostat location.

3.Attach thermostat wire to cord and pull wire through hole in wall so that 6” of wire protrudes.

REPLACEMENT INSTALLATION

REMOVE OLD THERMOSTAT

1.Shut off electricity at the main fuse box until installation is complete. Verify power is off with a voltmeter.

2.Remove the front cover of the old thermostat. With wires still attached, remove wall plate from the wall.

3.If the old thermostat has a wall mounting plate, remove the thermostat and the wall mounting plate as an assembly.

4.FOR HEATING ONLY SYSTEMS — Disconnect the two wires from the old thermostat. Skip steps 5 through 7 below and proceed to ATTACH SUBBASE TO WALL.

5.FOR HEATING/COOLING SYSTEMS — Before removing wires from old thermostat, identify the terminals that have wires attached on the old thermostat. Then use Table 1 to identify the type of thermostat you are replacing. For example, if the old thermostat has wires attached to terminals R, W, Y, and G, the old thermostat is a type 5 (note that the old thermostat may not have wires attached to all the terminals identified in Table 1).

6.Use the self-adhesive labels enclosed with your new thermostat to identify the wires attached to the old thermostat. The labels correspond to the thermostat type number you identified in step 5 above (see Table 2). For example, if you determined that the old thermostat is a type 5, use the labels for the type 5 thermostat (you may not use all the labels for the type number you’ve identified if the old thermostat did not have wires attached to all the terminals).

7.Label each wire as you disconnect it. The labels have both the old terminal markings and the new terminal identification. Discard any unused labels. PULL AT

LEAST SIX INCHES OF WIRE OUT OF THE WALL WHEN YOU DISCONNECT IT - DO NOT ALLOW THE WIRES TO FALL BACK INTO THE WALL.

ATTACH SUBBASE TO WALL

1.Remove the packing material from the thermostat. Place the fingers of one hand on the center top and bottom portion of the thermostat. Grasp the subbase in the other hand on the top and bottom center, and gently pull straight out (see fig. 2). The thermostat has pin and socket connectors. Forcing or prying on the thermostat will cause damage to the unit.

2.Pull wires through opening in the center of the subbase. DO NOT LET WIRES FALL BACK INTO

WALL.

3.Connect wires beneath terminal screws on subbase using appropriate wiring schematic (see figs. 3 through 8).

4.Place subbase over hole in wall and mark mounting hole locations on wall using subbase as a template.
