INSTALLATION
Inspection
Inspect the package for damage. If damaged, notify the
appropriate carrier immediately. If undamaged, open the
package and inspect the device for obvious damage. Return
damaged products.
Requirements
• Tools (not provided):
– Appropriate screwdriver for mounting the thermostat
– 20-881 Thermostat calibration and cover screw
wrench (or 1/16” and 1/4” hex wrenches)
• Training: Installer must be a qualified, experienced
technician
• Appropriate accessories
• Piping diagrams
Location
Caution:
• Do not locate the thermostat near sources of heat or
cold, such as lamps, motors, sunlight, or concealed
ducts or pipes. Doing so will affect the accuracy of the
thermostat.
• Avoid installing the thermostat on outside walls. If such a
location is necessary, mount the thermostat on an
insulated back plate (accessory item).
• Mount thermostats only after the wall surfaces have
been finished.
Locate the thermostat where it will be exposed to an
unrestricted circulation of air, which represents the average
temperature of the controlled space.
