Applications

IMPORTANT: The TEC20x6(H)-2 Series Wireless

Thermostat Controllers are 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 using 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. TEC20x6(H)-2 Series Wireless Thermostat
Controllers control two- or four-pipe fan coils, cabinet
unit heaters, or other equipment using on/off, floating,
or proportional 0 to 10 VDC control input, three speeds
of fan control, and dehumidification capability.

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

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 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)

User Interface Keys

The user interface consists of keys on the front cover
as illustrated in Figure 12. The function of each key is
as follows:

• OVERRIDE key (commercial models) overrides
the unoccupied mode to occupied at the local user
interface for the specified TOccT ime. (TOccTime is
defined by selecting the appropriate time period in
the Installer Configuration Menu.) The OVERRIDE
key also allows access to the Installer
Configuration Menu. (See Table 6.)

Note: If one of the binary inputs is configured to
operate as a remote override contact, this OVERRIDE
key is disabled.

• °C/°F key (hospitality models) changes the
temperature scale to either Celsius or Fahrenheit
and allows access to the Installer Configuration
Menu. (See Table 6.)

• UP/DOWN arrow keys change the configuration
parameters and activate a setpoint adjustment.

Light-Emitting Diodes (LEDs)

System Activity LEDs indicate the status and actions of
the thermostat controller.

•The FAN LED is on when the fan is on.

•The HEAT LED is on when heating or reheat is on.

•The COOL LED is on when cooling is on.

• MODE key toggles among the system modes
available, as defined by selecting the appr op ria te
operation sequence in the Installer Configuration
Menu (for example Off, Heat, Cool, Auto).

• FAN key toggles am on g th e fa n mo de s av aila ble ,
as defined by selecting the appropriate fan menu

Configuring the Thermostat Controller

The thermostat controller comes from the factory with
default settings for all configurable parameters. The
default settings are shown in Table 6. To reconfigure
the parameters, follow the steps in this section.

To access the Installer Configuration Menu, press and
hold the center key for approximately 8 seconds. Once
the Installer Configuration Menu begins, release and
press the center key to scroll through the parameters
listed in Table 6. When the desired parameter displays,
use the UP/DOWN arrow keys to choose the desired
selection option. Then press and release the center
key to continue scrolling through the parameters.

Backlit Liquid Crystal Display (LCD)

The thermostat controller includes a 2- line, 8-character
backlit display. Low-level backlighting is present during
normal operation, and it brightens when any user
interface key is pressed. The backlight returns to low
level when the thermostat controller is left unattended
for 45 seconds.

Status Display Menu

The Status Display Menu displays during normal
operation. This menu scrolls through several
parameters:

• Room Temperature

• Room Temperature and Humidity (TEC2036-2,
TEC2036H-2, TEC2056-2, and TEC2056H-2
models)

• System Mode

• Occupancy Status (Occupied/Unoccupied/
Override)

• Applicable Alarms – The backlight lights up as an
alarm condition is displayed.

Note: An option is available within the Installer
Configuration Menu to lock out the scrolling display and
show only the Room Temperature parameter.

Note: Pressing the FAN key during configuration
restarts the list of displayed parameters at the first
parameter listed in Table 6.

When the thermostat controller is in the Installer
Configuration Menu and left unattended for
approximately 8 seconds, the thermostat controller
reverts to the Status Display Menu.

Configuring Inputs BI1, BI2, and UI3

When BI1 and BI2 are configured for an alarm
condition, an alarm condition displays locally when the
input closes. An alarm message is included on the
scrolling Status Display Menu and when the message
is displayed, the backlight momentarily lights up.

The UI3 input provides changeover of hot/cold water
switching or supply air temperature monitoring at the
thermostat controller.

Each input can be configured to the Selection Options
included in Table 6.

Configuring the Sequence of Operation (S eqOpera)

Choose the appropriate sequence of operation. The
modes presented are user-dependent on the sequen ce
of operation selected. For two-pipe applications using a
changeover sensor, choose the selection option

(0): Cooling Only. Changeover occurs between
Cooling Only and Heating Only. See Figure 13

through Figure 18 for sequence of operation
examples.

Configuring the Wireless Mesh Network Settings

Use the following process to configure the wireless
mesh network.

1. Select a PAN ID and Channel. Use these same
values for every TEC Wireless Thermostat
Controller (and the associated TEC20 Coordinator)
on the same wireless mesh network. See Table 6.

2. Select a Com Address for each TEC Wireless
Thermostat Controller (1 to 254). This address
must be unique to each TEC Wireless Thermostat
Controller on the same wireless network (that is,
unique to the PAN ID/Channel combination). See
Table 6.

After configuring the wireless mesh network settings,
refer to the TEC Series Wireless Thermostat Controller
System T echnical Bulletin (LIT-12011414) for directions
on integrating the TEC Wireless Thermostat
Controllers and TEC20 Coordinator with a supervisory
controller.

Dehumidification (TEC2036[H]-2 and TEC2056[H]-2
Models Only)

Upon detection of room humidity above the adjustable
humidity setpoint as sensed by the integral humidity
sensor, dehumidifica tion activates.

Note: Dehumidification operation functions only in the
Cooling mode; dehumidification operation does not
function in either the Off or the Heating mode.

Note: A central network command can globally
lock out dehumidification operation to all thermostat
controllers.

If the room temperature resides in the deadband
between the Heating and Cooling setpoint:

• the thermostat controller forces the fan to low
speed

• the chilled water valve opens to the specified
maximum value set by CoolMax

• the thermostat controller stages Heating to
maintain the room temperature at the Cooling
setpoint, as sensed by the thermostat controller

If the room temperature falls below the current Heating
setpoint, the thermostat controller disables
dehumidification operation.

If the thermostat controller is in Cooling demand:

• the chilled water valve opens to 100%

• the thermostat controller stages Heating to
maintain the room temperature at the Cooling
setpoint, as sensed by the thermostat controller

If the thermostat controller is in Cooling demand and
the room temperature rises 2F°/1C° above the Cooling
setpoint, the thermostat controller automatically
disables dehumidification operation. Likewise, if the
thermostat controller is in Cooling demand and the
room temperature falls below the current Heating
setpoint, the thermostat controller disables
dehumidification operation.

BI1 Configuration of Binary Input 1.

Default: None

BI2 Configuration of Binary Input 2.

Default: None

(None): No function is associated with an input.
(Rem NSB): Remote Night Setback (NSB) via a time clock input, an

occupancy sensor, or from a voltage-free contact.
Contact open = Occupied; contact closed = Unoccupied.

(MotionNO*): Temporary occupancy request via a motion detector
input. Contact open = Unoccupied. When the contact closes, the
thermostat controller goes into the occupied mode for a specified
TOccTime. Once the TOccTime begins, the thermostat controller
remains in the occupied mode if the contact is open, until the
TOccTime expires.

(MotionNC*): Temp orary occupancy request via a motion detector
input. Contact closed = Unoccupied. When the contact opens, the
thermostat controller goes into the occupied mode for a specified
TOccTime. Once the TOccTime begins, the thermostat controller
remains in the occupied mode if the contact is closed, until the
TOccTime expires.

(Window): Cancels the heating or cooling action when a window is
open. The fan operation is only affected if the Fan Menu parameter
is set to (4): On-Auto and Auto is the selected fan mode. A window
alarm appears, indicating that the window needs to be closed to
resume heating or cooling.

*These settings disable any local override function.

(None): No function is associated with an input.
(Door Dry): Door contact only has an effect if BI1 is set to

MotionNO or MotionNC. (See the BI1 parameter earlier in this

table.) The occupancy is now dictated via BI1 and BI2. Any motion
detected sets the zone to Occupied status. The thermostat controller
remains in the occupied mode until a DoorOpen is detected, at
which point the thermostat controller goes to the unoccupied mode.
If the door stays open more than the specified door time, the
thermostat controller remains unoccupied. (See the Door Time
parameter later in this table.)

(RemOVR): Temporary occupancy request via a remote input. This
override function is controlled by a manual remote occupancy
override. When enabled, this condition disables the override
capability of the thermostat controller.

(Filter): A Filter alarm is displayed. This alarm can be connected to
a differential pressure switch that monitors a filter.

(Service): A Service alarm is displayed on the thermostat controller
when the input is energized. This input can be tied into the air
conditioning unit control card, which provides an alarm should there
be a malfunction.
