SELECT THERMOSTAT LOCATION
Proper location insures that the humidity control will
provide a desired humidity level throughout the home.
Observe the following general rules when selecting a
location.
1. Locate humidity control about 5 ft. above the floor.
2. Install humidity control on a partitioning wall, not on
an outside wall.
3. For most residential applications locate humidity
control adjacent to the existing wall thermostat for
easy installation and wiring.
4. Never expose humidity control to direct light from
lamps, sun, fireplaces or any temperature radiating
equipment.
5. Avoid locations close to windows, adjoining outside
walls, or doors that lead outside.
ROUTE WIRES TO LOCATION
All wiring must conform with local and national electri-
cal 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 houses,
drill 1/2" hole through ceiling and into partition from
above (see Fig. 1).

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 houses, drop cord
through hole in ceiling and down partitioning; snag
cord at the humidistat location.
3. Attach humidistat cable to cord and pull cable through
hole in wall so that 6" of cable protrudes.
4. Position a typical electrical re-work box over 1/2" hole
and cut around outline of electrical box. Pull wiring
through knockout and secure electrical box in wall.
