Location considerations
For networked models, 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
b
ehind doors
• Away from steam or water pipes, warm air stacks, unconditioned areas (not heated or cooled), or sources of
electrical interference
• In a clear path between the integrated passive infrared (PIR) occupancy sensor (if equipped) and the spac
ing monitored

For wireless models, also locate the thermostat controller:
• Outside of a recessed area, metal enclosure, or shelving unit
• On the same building level as the other wireless devices on the same personal area network (PAN)
• At least 2 in. (51 mm) away from any metal obstruction
• In the direct line of sight to other wireless devices on the same PAN. Signal transmission is best if the path
between the TEC3000 and other wireless devices is dire ct as pos sible . Lin e of sigh t is desir abl e but no t
required. See Table 1 for recommended and maximum distances.
• Away from metal and large solid obstructions (including equipment r ooms and elevator shafts and concrete or
brick walls) between the TEC3000 and the ZFR Pro Router/Repeater or ZFR Pro Coordinator Radio
• Within range of two or more wireless devices on the same PAN. Redundancy in the layout provides the best
reliability in wireless installations
• At least 20 ft (6 m) from a microwave oven
For integrated passive infrared (PIR) models, be sure that the thermostat controller is located centrally, where
occupant movement is frequent. Ensure that the unit is not blocked by a plastic tamper resistant enclosure (such
as the GRD10A-608). The plastic enclosure blocks the occupancy sensing capability.
The use of insulating foam pads is required for installations where wirin g passes through th e wall to the thermostat.
For wireless models, the effective transmission range and dist ance for indoor applications vary because of wireless
signal absorption and reflection due to metal obstructions, walls or floors, and furniture found in typical building
interiors.

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: 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. The controller version ans the base version must match to ensure proper operation.
IMPORTANT: Use proper Electrostatic Discharge (ESD) precautions during installation and servicing to avoid
damage to the electronic circuits of the thermostat controller.

(shown without occupancy sensor) (left) and removing the thermostat controller cover (right)
3. Align the thermostat controller mounting base on the wall with the security screw on the top and use the base
as a template to mark the two mounting hole locations. See Figure 3.
Notes:
• If you need to install the thermostat controller on an electrical junction box, use
2-1/2 x 4 in. (63 x 101 mm) square boxes with mud ring covers and avoid smaller 1-1/2 x 4 in.
(38 x 101 mm) square or 3 x 2 in. (76 x 51 mm) boxes. This procedure ensures that you have enough
space for cabling, if needed.
• For surface-mounted applications, use durable mounting hardware, such as wall anchors, that cannot be
easily pulled out of the mounting surface.
4. Pull approximately 6 in. (152 mm) of wire from the wall and insert the wire through the center hole in the
thermostat controller mounting base. See Figure 3.
5. Secure the mounting base to the wall surface using two mounting screws (user supplied) as illustrated in
Figure 3.
Note: Be careful not to overtighten the mounting screws.
