Mounting

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.
