Location Considerations
Locate the TEC3000 Series Thermostat Controller:
• on a partitioning wall, approximately 5 ft (1.5 m)
above the floor in a location of average
temperature, allowing for vertical air circulation to
the TEC
• away from direct sunlight, radiant heat, outside
walls, outside doors, air discharge grills,
stairwells, and from behind doors
• away from steam or water pipes, warm air stacks,
unconditioned areas (not heated or cooled), or
sources of electrical interference
For integrated passive infrared (PIR) models, be sure
that the thermostat controller is located centrally,
where occupant movement is frequent.
Use insulating foam pads for installations where
wiring passes through the wall to the thermostat.
Note: Allow for sufficient clearance to insert a USB
drive into the USB port.
Installing the Thermostat Controller
1. Use a 1/16 in. (1.5 mm) Allen wrench or Johnson Controls® T-4000-119 Allen-Head Adjustment Tool (order
separately) to remove the security screw if it is installed on the top of the thermostat controller cover as
illustrated in Figure 2.
2. Pull the top edge of the cover and open the thermostat controller as illustrated in Figure 2.
IMPORTANT: Only connect memory devices to the USB port. Do not use it for charging external devices.
IMPORTANT: The cover is not secured on the bottom. Be careful not to drop the cover.
IMPORTANT: If you are installing more than one thermostat controller, keep track of which cover attaches to
which base.
IMPORTANT: Use proper Electrostatic Discharge (ESD) precautions during installation and servicing to avoid
damage to the electronic circuits of the thermostat controller.
