Mounting and Wiring
To ensure correct operation, observe the following requirements when choosing a location
for the thermostat:
•
Locate the thermostat where it will be exposed to the unrestricted circulation of air which
represents the average temperature of the controlled space.
•
Mount the thermostat approximately 5 ft. (1.5 m) above floor level on a flat, vertical sur-
face.
•
When installing a 2x4 junction box for a thermostat, orient the junction box horizontally if
possible.
C A U T I O N
•
Do not exceed the ratings of the thermostat. Doing so may result in damage to the thermo-
stat.
•
Do not locate the thermostat near sources of heat or cold such as lamps, motors, sun-
light, or concealed ducts or pipes. Doing so may result in inaccurate temperature control
due to erroneous temperature sensing.
•
The thermostat is designed for service in any normally encountered human environment.
Avoid locations where excessive vibration, moisture, corrosive fumes or vapors are
present. Such locations may damage the thermostat or shorten its service life. NEMA
Type 1 covers are intended for indoor use, primarily to provide a degree of protection
against contact with the enclosed equipment.
Mounting Directly onto Wall
1. Gently pry the temperature setpoint dial from the thermostat, using a screwdriver, to
expose the screw which secures the housing to the thermostat mechanism.
2. Remove the attaching screw and separate the housing from the thermostat mechanism.
3. Position the thermostat mechanism upright, in the desired location on the wall.
C A U T I O N
Mount the thermostat upright so that the ventilation slots in its housing are at the top and
bottom. This is necessary to ensure a free flow of air over the sensing mechanism.
4. Using the base of the thermostat as a template, mark the locations of the mounting
holes on the wall. Refer to dimensions in Figure-5 .
5. Drill the mounting holes in the wall, using an appropriately sized drill.
