Installation
Location Considerations
Locate the TEC22x4-3 thermostat:
•
on a partitioning wall, approximately 5 ft (1.5 m)
above the floor in a location of average
temperature
•
away from direct sunlight, radiant heat, outside
walls, behind doors, air discharge grills, stairwells,
or outside doors
•
away from steam or water pipes, warm air stacks,
unconditioned areas (not heated or cooled), or
sources of electrical interference
Note:
Allow for vertical air circulation to the
TEC22x4-3 thermostat.
To install the thermostat:
1.
Use a Phillips-head screwdriver to remove the
security screw on the bottom of the thermostat
cover.
2.
Pull the bottom edge of the thermostat cover and
open the thermostat as illustrated in Figure 1.
IMPORTANT:
The TEC22x4-3 thermostats are
intended to provide an input to equipment under
normal operating conditions. Where failure or
malfunction of the thermostat could lead to personal
injury or property damage to the controlled
equipment or other property, additional precautions
must be designed into the control system.
Incorporate and maintain other devices such as
supervisory or alarm systems or safety or limit
controls intended to warn of, or protect against,
failure or malfunction of the thermostat.
