Part No. 24-9890-1109, Rev. B

Issued July 13, 2010

Supersedes May 17, 2010

Application

IMPORTANT: The TEC2045-4 Wireless

Thermostat Controller is intended to provide an input
to equipment under normal operating conditions.
Where failure or malfunction of the thermostat
controller could lead to personal injury or property
damage to the controlled equipment or other
property, additional precautions must be designed
into the control system. Incorporate and maintain
other devices, such as supervisory or alarm systems
or safety or limit controls, intended to warn of or
protect against failure or malfunction of the
thermostat controller.

The TEC Series Wireless Thermostat Controller
System provides wireless networked control of
Heating, Ventilating, and Air Conditioning (HVAC)
equipment on a Building Automation System (BAS)
that enables remote monitoring and programming. This
TEC Series System integrates into a supervisory
controller that uses BACnet® Internet Protocol (IP) or
BACnet Master-Slave/Token-Passing (MS/TP)
communications.

TEC20 Coordinators allow the supervisory controlle r to
communicate with multiple TEC Wireless Thermostat
Controllers. TEC2045-4 Wireless Thermostat
Controllers control two-pipe fan coils, cabinet unit
heaters, or other equipment using a proportional
0 to 10 VDC control input and one-speed fan control.

The wireless mesh network uses ZigBee™ technology
to enable remote monitoring and programming and to
enhance reliability by providing redundant transmission
paths through other TEC Wireless Thermostat
Controllers, creating a resilient, self-healing mesh
network.

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 re flectio n due to
metal obstructions, walls (or floors), and furniture found

in typical building interiors.

Table 1: Recommended Transmission Ranges

Type Distance

Through Walls 10 m (32.8 ft)
Open Space 30 m (98.4 ft)

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.

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.

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.

6. Position the thermostat mounting base on the wall
so that the arrow on the base points upward to
indicate the top of the thermostat.

7. Secure the mounting base to the wall surface using
two mounting screws as illustrated in Figure 3.

Note: Be careful not to overtighten the mounting
screws.

Wiring

CAUTION: Risk of Electric Shock.

Disconnect the power supply before
making electrical connections to avoid
electric shock.

CAUTION: Risk of Property Damage.

Do not apply power to the system before
checking all wiring connections. Short
circuited or improperly connected wires
may result in permanent damage to the
equipment.

IMPORTANT: Make all wiring connections in
accordance with local, national, and regional
regulations. Do not exceed the electrical ratings of
the thermostat controller.

When replacing an existing thermostat controller,
remove and label the wires to identify the terminal
functions. When replacing a thermostat controller o f the
same model, simply remove the old screw terminal
blocks, and reinsert them onto the PCB of the
replacement thermostat controller.

8. Swing the PCB back to the right, and carefully
snap it into the locking tabs on the mounting base.

9. Remove the screw terminal blocks that are
attached to a disposable adhesive. Figure 4

a larger proportional band can be used to solve issues for flawed
HVAC design with basic sizing and thermostat controller location
errors that cannot be worked around.

thermostat controller is in the

Unoccupied mode) when a

Schedule Override Function is

enabled using either the Main User

Menu or BI1 or BI2 configured as a

temporary override remote contact

(RemOVR).

Sets the effective duration of the

Temporary hea ting or cooling

setpoints set using the

UP/DOWN arrow keys.

Default: 2.0 hrs
Deadband Sets the minimum deadband

between the heating and cooling

setpoints.

Default: 2.0F°/1.0C°
Cal RS Sets the desired room air sensor

calibration (offset). The offset can

be added to or subtracted from the

actual displayed room temperature.

Default: 0.0F°/0.0C°

(temporar): Local changes to the heating or cooling setpoints are
temporary, and remain effective for the specified TOccTime.

(permnent): Local changes to the heating or cooling setpoints are
permanently stored in the thermostat controller memory.

(Attch Stp): Single Occupied Setpoint Adjustment. The displayed
setpoint is the setpoint from the last action taken by the thermostat
controller, or the setpoint currently in use. Both the heating and
cooling setpoints are changed simultaneously, while respecting the
minimum configured deadband. If one setpoint is desired over the
other, use the MODE key to toggle between the two setpoints.

(Dual Stp): Dual Occupied Setpoint Adjustment. The displayed
setpoint is the setpoint from the last action taken by the thermostat
controller, or the setpoint currently in use. The heating and cooling
setpoints can be separated individually, allowing the minimum
configured deadband to expand. If one setpoint is desired over the
other, use the MODE key to toggle between the two setpoints.
