Installation Instructions

Installation
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
Note:
Allow for vertical air circulation to the
TEC2045-4 Thermostat Controllers.
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.
Installing the Thermostat Controller
Follow these steps to install the thermostat controller:
1.
Use a Phillips-head screwdriver to remove the
security screw if it is installed on the bottom of the
thermostat controller cover.
Note:
Normally, the security screw is packaged
separately in a plastic bag with the thermostat
controller. Skip this step if the screw is not installed
on the bottom of the cover.
2.
Pull the bottom edge of the thermostat cover and
open the thermostat 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:
If you need to install the thermostat 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 you have enough space for
cabling and end-of-line devices, if needed.
