Applications

The TEC3000 Series Single- or Two-Stage Economizer Thermostat Controllers are stand-alone and field-selectable BACnet® MS/TP or N2 networked devices that provide control of the following:

• unitary rooftop units (RTUs)

• unitary RTUs with economizers

• unitary RTUs with heat pumps

• unitary RTUs with economizers and heat pumps The networked models feature a field-selectable Building Automation System (BAS) BACnet MS/TP or N2

communication capability 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 onboard touchscreen UI with backlit display that makes setup and operation quick and easy. Only the single-speed fan configuration is supported for fan coil equipment types.

IMPORTANT: The TEC3000 Series 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.

IMPORTANT: Le TEC3000 Series Thermostat Controller est destiné à transmettre des données entrantes à un équipement dans des conditions normales de fonctionnement. Lorsqu'une défaillance ou un dysfonctionnement du thermostat controller risque de provoquer des blessur es ou d'endommager l'équipe ment contrôlé ou un autre équipement, la conception du système de con tr ôle doit intégrer des dispositifs de protection supplémentaires. Veiller dans ce cas à intégrer de façon permanente d'autres dispositifs, tels que des systèmes de supervision ou d'alarme, ou des dispositifs de sécurité ou de limitation, ayant une fonction d'avertissement ou de protection en cas de défaillance ou de dysfonctionnement du thermostat controller.

Installation

Parts Included

• one TEC3000 Series Thermostat Contr oller with integral mounting base

• one installation instructions sheet

Location Considerations

Locate the TEC3000 Series 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

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

Use insulating foam pads for installations where wiring passes through the wall to the thermostat.

Note: Allow for sufficient clearance to insert a USB drive into the USB port.

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

FIG:security screw

FIG:ther mostat cover

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. See 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.

IMPORTANT: Use proper Electrostatic Discharge (ESD) precautions during installation and servicing to avoid damage to the electronic circuits of the thermostat controller.

Figure 2: Removing the Security Screw from the Thermostat Controller Cover

(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 Fig ur e 3.

Notes:

• If you need to install the thermostat controller on an elec trical 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.
