Dehumidification Capability Quick Start Guide

For wireless models, also locate the thermostat controller:

• 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

• 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

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

occupant movement is frequent. Ensure that the unit is not blocked by a plastic tamper resistant enclosure (such

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

The use of insulating foam pads is required for installations where wiring passes through the wall to the thermostat.

For wireless models, 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.

Notes:

• Allow for sufficient clearance to insert a USB drive into the USB port

• 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).

Installing the thermostat controller

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

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

illustrated in Figure 2.

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

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 controller version ans the base version must match to ensure proper operation.

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

damage to the electronic circuits of the thermostat controller.

(shown without occupancy sensor) (left) and removing the thermostat controller cover (right)

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.

Note: Be careful not to overtighten the mounting screws.

Wiring

Whenanexistingthermostatcontrollerisreplaced,removeandlabelthewirestoidentifytheterminalfunctions.

To wire the thermostat controller:

1. Strip the ends of each wire 1/4 in. (6 mm) and connect them to the appropriate screw terminals as indicated in

Table 2.

Note: For more details on wiring the MS/TP Communications Bus, refer to the MS/TP Communications Bus

Technical Bulletin (LIT-12011034).

2. Attach the communication wires to the terminal block.

Note: If multiple wires are inserted into the terminals, be sure to properly twist the wires together before

inserting them into the terminal connectors.

3. Carefully push any excess wire back into the wall.

Note: Seal the hole in the wall with fireproof material to prevent drafts from affecting the ambient temperature

readings.

4. For networked models, set the bus end-of-line (EOL) termination switch to the desired location.

Risk of Electric Shock.

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

Risque de décharge électrique.

Débrancher l'alimentation avant de réaliser tout raccordement électrique afin d'éviter tout risque de décharge

électrique.

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.

Risque de dégâts matériels.

Ne pas mettre le système sous tension avant d'avoir vérifié tous les raccords de câblage. Des fils formant un

court-circuit ou connectés de façon incorrecte risquent d'endommager irrémédiablement l'équipement.

IMPORTANT: Make all wiring connections in accordance with local, national, and regional regulations. Do not

exceed the electrical ratings of the TEC3000 Series Thermostat Controller.

IMPORTANT: Use proper ESD precautions during installation and servicing to avoid damage to the electronic

circuits of the thermostat controller.

Dehumidification Capability Quick Start Guide

The bus EOL termination switch allows you to designate the thermostat controller as the end of the Field

Controller (FC) Bus and N2 Bus. The default position is OFF. If the thermostat controller is at the end of a daisy

chain of devices on the FC Bus and N2 Bus, set the EOL switch to the ON position. See Figure 3.

5. Reattach the thermostat controller cover to the mounting base (bottom side first).

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

separately) to reinstall the security screw on the top of the thermostat controller cover. See Figure 2 for security

screw placement.

7. Remove the protective plastic cover sheet from the display.

Notes:

• For VAV and two-pipe systems, connect the valve to the heating output.

• Only one transformer is required for each TEC.

• Power to the AUX contact comes from the reheat coil.

IMPORTANT: Make sure you reattach the cover that corresponds to its correct base. The CPU board number

needs to match the base board number. Otherwise, an operation error occurs after you reattach a cover and

base that do not belong together.

IMPORTANT: If the display is dirty, gently wipe it clean with isopropyl alcohol or ethyl alcohol. Do not scrub

hard as to avoid damaging the surface. Do not use other cleaners such as water, ketones, and aromatic

solvents, since they may damage the polarizer.
