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 blessures ou d'endommager l'équipement contrôlé ou un autre
équipement, la conception du système de contrôle 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.

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

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 and Figure 7.
Note: For more details on wiring the MS/TP Communications Bus, refer to the MS/TP Communications Bus
Technical Bulletin (LIT-12011034).
2. 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.
3. Reattach 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.
4. Set the bus end-of-line (EOL) termination switch to the desired location on the TEC3630-00-000 and
TEC3631-00-000 models only.
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 4.
Figure 4: EOL Switch Positions (Left) and Installing the Thermostat Controller Cover (Right)
5. Reattach the thermostat controller cover to the mounting base (bottom side first).
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.
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 (as shown in Figure 5). See Table 1 for TEC3000 model names and code
numbers.
