INSTALLATION

NEW INSTALLATION

You should program the thermostat with batteries installed before attaching on subbase. See OPERA- TION 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 equip- ment.

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 basementless buildings, 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 basementless buildings, drop cord through hole in ceiling and down partitioning; snag cord at the thermostat location.

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