INSTALLATION INSTRUCTIONS
LOCATION
To ensure proper operation, the thermostat should be mounted on an inside wall in a frequently occupied area of the building. In addition, its position must be at least 18" (46cm) from any outside wall, and approx- imately 5' (1.5m) above the floor in a location with freely circulating air of an average temperature.
BE SURE TO AVOID THE FOLLOWING LOCATIONS:
-behind doors or in corners where freely circulating air is unavailable
-where direct sunlight or radiant heat from appli- ances might affect control operation
-on an outside wall
-adjacent to, or in line with, conditioned air dis- charge grilles, stairwells, or outside doors
-where its operation may be affected by steam or water pipes or warm air stacks in an adjacent parti- tion space, or by an unheated/uncooled area behind the thermostat
-where its operation will be affected by the supply air of an adjacent unit
-near sources of electrical interference such as arc- ing relay contacts

THERMOSTAT INSTALLATION
1.Insert a flat blade screwdriver or coin 1/8" into the slot located in the bottom center of the thermostat case and twist 1/4 turn. When you feel or hear a click, grasp the case from the bottom two corners and sep- arate from the subbase as shown in the diagram at the right. Some models require more force than oth- ers when separating due to the number of terminals on the subbase.
2.Swing the thermostat out from the bottom.
3.Lift the thermostat up and off the subbase.
4.Place the rectangular opening in the subbase over the equipment control wires protruding from the wall and, using the subbase as a template, mark the location of the two mounting holes (exact vertical mounting is necessary only for appearance).
5.Use the supplied anchors and screws for mounting on drywall or plaster; drill two 3/16" (5mm) diameter holes at the marked locations; use a hammer to tap the nylon anchors in flush to the wall surface and fas- ten subbase using the supplied screws. (Do not over- tighten!)
6.Connect the wires from your system to the thermostat terminals as shown in the wiring diagrams. Carefully dress the wires so that any excess is pushed back into the wall cavity or junction box. Ensure that the wires are flush to the plastic subbase. The access hole should be sealed or stuffed to prevent drafts from affecting the thermostat.
7.Before the thermostat is reinstalled on the subbase, install the optional indoor remote sensor (model 8002), if used. Refer to the installation instructions supplied with the model 8002.
REPLACING THE THERMOSTAT
ON THE SUBBASE
1.Position the thermostat on the hinged tabs located at the top of the subbase.
2.Gently swing the thermostat down and press on the bottom center edge until it snaps in place.
