Controller Installation Instructions 1

Applications

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 remotemonitoring 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 controller to

communicate with multiple TEC Wireless Thermostat

Controllers. TEC200x-4 Series Wireless Thermostat

Controllers provide networked control of a variety of

staged equipment. TEC2004-4 and TEC2004-4+PIR

Multi-Stage Economizer Wireless Thermostat

Controllers control economizer operation for single-

and multi-stage unitary rooftop equipment.

The TEC2004-4+PIR Thermostat Controller provides

advanced active occupancy logic that automatically

switches occupancy from Occupied to Unoccupied as

required by the presence of local activity. See the

Occupancy Sensor Operation – TEC2004-4+PIR

Thermostat Controller section for more information.

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.

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, outside doors, air discharge grills, or

stairwells, or from behind doors

• away from steam or water pipes, warm air stacks,

unconditioned areas (not heated or cooled), or

sources of electrical interference

For integrated Passive Infrared (PIR) models, make

sure the thermostat controller is located centrally,

where occupant movement is frequent.

Note: 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).

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 cover and open the

thermostat controller as illustrated in Figure 1.

Note: PIR Models have a wiring connection

between the cover and the Printed Circuit Board

(PCB). This connection allows for proper wiring of

the occupancy sensor. Carefully remove the wiring

connection from the PCB by pulling up on the

connector block. Do not attempt to remove the

connector block by pulling on the wires.

This Class (A) digital apparatus meets all the

requirements of the Canadian Interference-Causing

Equipment Regulations.

3. Carefully pull the locking tabs on the right side of

the mounting base and unlock the 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.

6. Position the mounting base so that the arrow on

the base points upward to indicate the top of the

thermostat controller.

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.

Note: For surface-mount applications, use

durable mounting hardware, such as Molly bolt

anchors, that cannot be easily pulled out of the

mounting surface.

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.

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

illustrates the locations of the screw terminal

blocks on the thermostat controller.

TEC2004-4 and TEC2004-4+PIR Multi-Stage Economizer Wireless Thermostat Controller

Installation Instructions

Integrated PIR Sensor –

TEC2004-4+PIR Thermostat Controller

The integrated PIR sensor allows for automatic

switching between fully adjustable Occupied and

Unoccupied temperature setpoints without user

interaction. This feature generates incremental energy

savings during scheduled occupied periods while the

space is unoccupied.

Programming Overview

Three menus are used to view, program, and configure

the TEC2004-4 and TEC2004-4+PIR Thermostat

Controllers: the Status Display Menu, the Main User

Menu, and the Installer Configuration Menu.

Status Display Menu

The Status Display Menu displays during normal

operation. This menu scrolls through several

parameters:

• Room Temperature

• System Mode

• Schedule Status (Occupied/Unoccupied/Override)

• Outdoor Temperature – An outdoor air temperature

sensor must be connected.

• Applicable Alarms – The backlight lights up as an

alarm condition is displayed.

Note: Press the YES key to temporarily stop this

menu from scrolling.

Note: An option is available within the Installer

Configuration Menu to lock out the scrolling display and

show only the Room Temperature parameter.

Main User Menu

Use the Main User Menu to access and change the

basic operating parameters of the thermostat controller.

Access the menu by pressing the MENU key during

normal thermostat controller operation.

Installer Configuration Menu

Use the Installer Configuration Menu to set up the

thermostat controller for application-specific operation.

To access the menu, press and hold the MENU key for

approximately 8 seconds.

Occupancy Sensor Operation –

TEC2004-4+PIR Thermostat Controller

A TEC2004-4+PIR Thermostat Controller (or a

TEC2004-4 Thermostat Controller equipped with a PIR

accessory cover) provides advanced occupancy logic.

Note: The PIR strategy is an occupied strategy. If the

thermostat controller is programmed to be Unoccupied,

the PIR function does not have an effect on the

occupancy strategy.

The thermostat controller automatically switches the

occupancy level between Occupied and Unoccupiedas

required, when local movement is sensed. In the

Occupied mode, if no movement is detected beyond

the Unocc TM parameter setting, the mode changes to

Unoccupied. Once movement is detected, the mode

changes back to Occupied.

Occupancy sensing is enabled only if a PIR cover is

installed. The PIR cover is auto detected when

installed.

PIR Diagnostic LEDs

The diagnostic LEDs inside the PIR lens brighten when

movement is detected within the first 30 minutes after

powerup. The LEDs do not light up or brighten after the

initial 30-minute period.

Setpoints

The installer must be certain that the difference

between the Occupied and Unoccupied setpoints can

be recovered within a timely fashion to ensure

occupancy comfort. In addition, the difference between

the two setpoints must be large enough to warrant

maximum energy savings.

These setpoints and Unoccupied time are adjustable to

allow for customization, as dictated by the individual

space requirements. See Figure 7 for an example of

increasing room temperature setpoints.

Settings

Use the following process to configure the wireless

mesh network settings.

1. Select a PAN ID and Channel. Use these same

values for every TEC Wireless Thermostat

Controller (and the associated coordinator) on the

same wireless mesh network.

2. Select a Com Address for each TEC Wireless

Thermostat Controller (1 to 254). This address

must be unique to each thermostat controller on

the same wireless network (that is, unique to the

PAN ID and Channel combination).

After configuring the wireless mesh network settings,

refer to the TEC20xx-4 and TEC20xx-4+PIR Series

Wireless Thermostat Controller System Technical
