Part No. 24-9890-757, Rev. —

Release 4.0

Issued March 17, 2008

Application

IMPORTANT: The TEC2045-2 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 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. TEC2045-2 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.

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

in typical building interiors.

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 is displayed during normal operation. This menu continuously scrolls through the following parameters:

• Room Temperature

• 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.

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 5. To reconfigure the parameters using the user interface keys, 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 5. 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.

Note: Pressing the FAN key during configuration restarts the list of displayed parameters at the first parameter listed in Table 5.

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 4.

Configuring the Sequence of Operation (SeqOpera)

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