Preparation

Check thermostat and subbase suitability for the heat-ing, cooling, or heating/cooling system. Refer to Table 1. Assemble tools required: flat bladed screwdriver, hand or power drill with 3/16-in. drill bit, wire cutter/stripper or sharp knife, bubble level or plumb bob and line.
Assure power is off to the heating, cooling, or heating/cooling system at the main fuse panel. Most buildings have a separate switch box or circuit breaker for disconnecting power to the heating and cooling (if applicable) equipment.
This thermostat is compatible with virtually all heating, cooling or heating/cooling systems. Refer to Table 1 for additional thermostat compatibility information.

TABLE 1—THERMOSTAT AND SYSTEM COMPATIBILITY.

If this control is replacing a control that contains mercury in a sealed tube, do not place your old control in the trash.
Contact your local waste management authority for instructions regarding recycling and the proper disposal of this control, or of an old control containing mercury in a sealed tube.

Installation

WHEN INSTALLING THIS PRODUCT…

1. Read these instructions carefully. Failure to follow them could cause a hazardous condition.
2. Installer must be a trained experienced service technician.
3. After installation is complete, check out product operation as provided in these instructions.
   IMPORTANT: An incorrectly leveled subbase will cause the temperature control to deviate from setpoint. It is not a calibration problem.

CAUTION

1. Disconnect power supply to prevent electrical shock or equipment damage.
2. To prevent interference with the thermostat linkage, keep wire length to a minimum and run wires as close as possible to the subbase.
3. Do not overtighten thermostat captive mounting screws because damage to subbase threads can result.
4. Do not short across coil terminals on relay.
   This can burn out the thermostat heat anticipator.

LOCATION
Locate thermostat about 5 ft (1.5m) above the floor in an area with good air circulation at average temperature. Do not mount the thermostat where it may be affected by—
— drafts, or dead spots behind doors and in corners.
— hot or cold air from ducts.
— radiant heat from the sun or appliances.
— concealed pipes and chimneys.
— unheated (uncooled) areas such as an outside wall behind the thermostat.
Run wires from the heating, cooling, or heating/cooling equipment to the new thermostat location.

UNPACK THERMOSTAT
Handle your new thermostat carefully; rough handling may interfere with its accuracy. Before unpacking, refer to Fig. 1.
Remove and discard the shipping wrap.
IMPORTANT: Save package of screws and instructions for the homeowner.
Remove the thermostat cover by lifting from the bottom.
Set aside cover until needed later.
Carefully remove the material protecting the mercury switch bulb.
Loosen two captive mounting screws.

MOUNT SUBBASE
Wall Mounting (Fig. 2)
Hold the subbase in position on wall (Fig. 2).
Mark holes on the wall for anchors. Use spirit level to make sure the wallplate or subbase is level.
Drill 3/16-in. holes, and gently tap anchors into holes until flush with the wall.
Pull wires through the large wiring hole in the subbase.
Loosely fasten the subbase to the wall with the three
screws. Do not completely tighten the screws.
Carefully level the subbase (Fig. 3), and firmly tighten the screws.

Fig. 2—Mounting subbase to wall.

Outlet Box Mounting (Fig. 4)
Use a horizontally mounted outlet box if possible. If a vertical outlet box is used, the subbase must be mounted on a 202689A Cover Plate Assembly (ordered separately).
Follow the instructions provided with the cover plate assembly.
Align the subbase mounting holes on the outlet box and loosely fasten with the two screws.
Carefully level the subbase (Fig. 3) and firmly tighten the screws.

INSERT TIMER BATTERIES
Power is supplied to the timer by two AAA alkaline batteries (not included).
Install the batteries in the thermostat (Fig. 7).
Once a year or when batteries are dead, replace with two new AAA alkaline batteries. We recommend Energizer® batteries.

Fig. 7—Insert timer batteries.

SET TIMER
Adjust the timer by moving the knob clockwise .
Do NOT reverse the knob.
When time is correctly set, the time indicator arrow (Fig. 8) must point to the corresponding daytime (light) or nighttime (dark) portion of the program dial.

Fig. 8—Set timer.

ATTACH THERMOSTAT COVER
Make sure the packing inserts in the thermostat base are removed.
Place the two tabs on the upper edge of the cover into the mounting slots in the thermostat base (Fig. 9).
Swing the cover downward until it catches at the bottom of the base.

Fig. 9—Attach cover.

SET TEMPERATURE CONTROL LEVERS
The two levers on top of thermostat control the low and high temperatures for energy savings and comfort control (Fig. 10). The lever on the left (blue mark) controls the lower temperature. The lever on the right (red mark) controls the higher temperature.
We recommend pushing the levers together at an appropriate temperature for either heat or cool until the occupant programs the thermostat and makes the final temperature selections.

Fig. 10—Temperature control levers.

SET SUBBASE SWITCHES
The subbase system switch controls system operation as follows:
HEAT: Heating system is controlled by the thermostat.
Cooling system is off.
COOL: Cooling system is controlled by the thermostat.
Heating system is off.
OFF: Both the heating and cooling systems are off. If the fan switch is in the AUTO position, the fan is also off.
The subbase fan switch controls fan operation as follows:
ON: Fan operates continuously.
AUTO: Fan operates with the cooling equipment as controlled by the thermostat or with the heating equipment as controlled by the plenum switch. In electric heat, heat pump and fan coil systems, the fan is controlled by the thermostat in heating and cooling.
To switch positions, use thumb or index finger to slide lever to the desired position. Switch lever must stop in detent over the desired function indicator mark for proper circuit operation.

CHECK OUT THERMOSTAT OPERATION

CAUTION
Do NOT check operation by shorting across terminals of relay or valve coil; this will burn out the thermostat heat anticipator.

HEATING/COOLING SYSTEM
Turn on power to the furnace and cooling system.
Place the system switch lever to HEAT and fan switch lever to AUTO.
Push both temperature setting levers together at least 5°F (3°C) above room temperature. The main burner should come on. The fan will start when the furnace heats up. (If central electric heat or heat pump system, fan starts immediately.)
Move both levers 5°F (3°C) below room temperature.
The burner should shut off.
Place the system switch lever at COOL and the fan switch lever at AUTO. The cooling equipment should operate, and the fan will start. Allow for any time delay that may be built into the compressor control circuit.
NOTE: To avoid compressor damage, do not operate the system if outdoor temperature is below 50°F (10°C).
Refer to manufacturer recommendations.
Move both temperature setting levers together at least 5°F (3°C) above room temperature. The cooling equipment should shut off.
Place the fan switch to ON. The fan should run continuously with the system switch in any position.
Place the system switch to OFF. Move both temperature setting levers to various positions. The heating and cooling systems should not operate.
Operate the entire system for at least one complete cycle with the system switch at COOL and one complete cycle with the switch at HEAT.
If thermostat fails any test, refer to the Troubleshooting Guide in the Owner’s Manual.
Reset both temperature setting levers to the desired temperatures.
Leave Owner’s Manual and Assistance Information in a convenient place for the building occupant or provide with other appliance manuals.
