INSTALLATION
Thermostats require upright mounting on a properly flat
surface. Locate thermostat where it will be exposed to
unrestricted circulation of air which represents the average
temperature of the controlled space. Install thermostat in any
normal human environment.
Caution: Do not locate the thermostat near sources of heat
or cold, such as lamps, motors, sunlight, or concealed ducts
or pipes. Avoid locations where excessive vibration,
moisture, corrosive fumes or vapors are present. NEMA Type
1 covers are intended to provide a degree of protection
against contact with the enclosed equipment.

2. Fasten mounting plate to switch box (Figure 2).
3. Make electrical connections to switch leads and
thermostat terminals. (See Figure 4 for typical wiring
