Location Considerations
Locate a thermostat controller:
•
on a partitioning wall, approximately 1.5 m (5 ft)
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
Allow for vertical air circulation to the thermostat
controller.
Wireless Signal Transmission Range
Line-of-sight transmission ranges between a
TEC20 Coordinator and a TEC Wireless Thermostat
Controller (or between TEC Wireless Thermostat
Controllers) can be less than the recommended
distances shown in Table 1. The effective transmission
range for indoor applications varies because of Radio
Frequency (RF) signal absorption and reflection due to
metal obstructions, walls (or floors), and furniture found
in typical building interiors.

For detailed information on locating devices for
optimum signal strength, refer to the Wireless Metasys
System Location Guide (LIT-12011294), which is
available on the Johnson Controls® Portal intranet site.
Mounting the Thermostat Controller
Follow these steps to mount the thermostat controller:
1. Use a Phillips-head screwdriver to loosen the
security screw (if installed) on the bottom of the
cover.

2. Pull the bottom edge of the cover and open the
thermostat controller as illustrated in Figure 1.

3. Carefully pull the locking tabs on the right side of
the mounting base and unlock the Printed Circuit
Board (PCB). Open the PCB to the left as
illustrated in Figure 2.

4. Pull approximately 152 mm (6 in.) of wire from the
wall, and insert the wire through the hole in the
mounting base.
5. Align the mounting base on the wall, and use the
base as a template to mark the two mounting hole
locations.
Note: Be sure to position the mounting base so that
the arrow on the base points upward to indicate the top
of the thermostat controller.
6. Drill a 5 mm (3/16 in.) hole at each of the two
marked locations, and tap nylon anchors (included)
flush to the wall surface.
Note: Other means of anchoring the device may be
desired, depending on the wall medium.
