Applications
The TEC3000 Series On/Off or Floating Fan Coil and Individual Zone Thermostat Controllers are stand-alone and
field-selectable BACnet® MS/TP or N2 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 an on/off or floating control input
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. 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/or 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).

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.
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 as
illustrated in Figure 2.
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.
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.
Note: Be careful not to overtighten the mounting screws.

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 6 or 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 TEC3610-00-000,
TEC3611-00-000, TEC3612-00-000, and TEC3613-00-000 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.

5. Reattach the thermostat controller cover to the mounting base (bottom side first).
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 on page 7 for TEC3000 model names and
code numbers.
