Refer to the QuickLIT website for the most up-to-date version of this document.

Applications

The TEC3000 Series Wireless Proportional Fan Coil and Individual Zone Thermostat Controllers are wireless

networked devices that provide control of the following:

• local hydronic reheat valves

• pressure-dependent variable air volume (VAV) equipment with or without local reheat

• two- or four-pipe fan coils

• cabinet unit heaters

• other individual zone equipment using a proportional 0 to 10 VDC control input

The networked models are compatible with the WNC1800/ZFR182x Pro Series Wireless Field Bus System that

enables remote monitoring and programming for efficient space temperature control.All models include a USB port

configuration that reduces installation time by allowing simple backup and restore features from a USB drive, which

enables rapid cloning of configuration between like units.

Some models have occupancy sensing capability built into the device. These thermostat controllers maximize up to

30% energy savings in high-energy usage commercial buildings, such as schools and hotels, during occupied

times by using additional standby setpoints.

All models feature an intuitive UI with backlit display that makes setup and operation quick and easy. Multiple fan

configurations are supported for fan coil equipment types:

• single-speed

• multi-speed (two or three discrete speeds)

• variable-speed/EC motors (0 to 10 VDC control)

Some models support dehumidification on two-pipe fan coil units with reheat, and four-pipe fan coil units with or

without reheat. When no heating is required, the thermostat controller monitors space humidity and activates

dehumidification control as necessary. Heat and reheat is used as required to maintain the space temperature. For

optimal dehumidification performance, use a fan coil unit that has a multi-speed or variable-speed fan (VSF).

Capability Installation Instructions

Location Considerations

Locate the TEC3000 Series Wireless Thermostat Controller:

• on a partitioning wall, approximately 5 ft (1.5 m) above the floor in a location of average temperature, allowing

for vertical air circulation to the TEC

• away from direct sunlight, radiant heat, outside walls, outside doors, air discharge grills, stairwells, and from

behind doors

• away from steam or water pipes, warm air stacks, unconditioned areas (not heated or cooled), or sources of

electrical interference

• outside of a recessed area, metal enclosure, or shelving unit

• on the same building level as the other wireless devices on the same personal area network (PAN)

• at least 2 in. (51 mm) away from any metal obstruction

• in the direct line of sight to other wireless devices on the same PAN. Signal transmission is best if the path

between the TEC3000 and other wireless devices is direct as possible. Line of sight is desirable but not

required. See Table 1 for recommended and maximum distances.

• away from metal and large solid obstructions (including equipment rooms and elevator shafts and concrete or

brick walls) between the TEC3000 and the ZFR Pro Router/Repeater or ZFR Pro Coordinator Radio

• in a clear path between the integrated passive infrared (PIR) occupancy sensor (if equipped) and the space

being monitored

• within range of two or more wireless devices on the same PAN. Redundancy in the layout provides the best

reliability in wireless installations

• at least 20 ft (6 m) from a microwave oven

The effective transmission range and distance for indoor applications vary because of wireless signal absorption

and reflection due to metal obstructions, walls or floors, and furniture found in typical building interiors.

For integrated passive infrared (PIR) models, ensure that the thermostat controller is located centrally where

occupant movement is frequent, and where the unit is not blocked by a plastic tamper resistant enclosure (such as

the GRD10A-608). The plastic enclosure blocks the occupancy sensing capability.

Note: For more details on using ZFR Pro Series communication devices, refer to the WNC1800/ZFR182x Pro

Series Wireless Field Bus System Technical Bulletin (LIT-12012356).

Capability Installation Instructions

Note: Allow for sufficient clearance to insert a USB

drive into the USB port.

Use insulating foam pads for installations where wiring

passes through the wall to the thermostat.

Installing the Thermostat Controller

1. Use a 1/16 in. (1.5 mm)Allen wrench or Johnson Controls® T-4000-119 Allen-HeadAdjustment Tool (order

separately) to remove the security screw if it is installed on the top of the thermostat controller cover.

2. Pull the top edge of the cover and open the thermostat controller as illustrated in Figure 2

IMPORTANT: Only connect memory devices to the USB port. Do not use it for charging external devices.

IMPORTANT: The cover is not secured on the bottom. Be careful not to drop the cover.

IMPORTANT: If you are installing more than one thermostat controller, keep track of which cover attaches to

which base. The CPU board number needs to match the Base board number. Otherwise you will encounter an

operation error after you reattach a cover and base that do not belong together as shown in Figure 4. See

Table 2 for TEC3000 model names and code numbers.

IMPORTANT: Use proper Electrostatic Discharge (ESD) precautions during installation and servicing to avoid

damage to the electronic circuits of the thermostat controller.

3. Align the thermostat controller mounting base on the wall with the security screw on the top and use the base

as a template to mark the two mounting hole locations. See Figure 3.

Notes:

• If you need to install the thermostat controller 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 that you have enough

space for cabling, if needed.

• For surface-mounted applications, use durable mounting hardware, such as wall anchors, that cannot be

easily pulled out of the mounting surface.

4. Pull approximately 6 in. (152 mm) of wire from the wall and insert the wire through the center hole in the

thermostat controller mounting base. See Figure 3.

5. Secure the mounting base to the wall surface using two mounting screws (user supplied) as illustrated in

Figure 3.
