TEC3000 Series Wireless Proportional Fan Coil and
Individual Zone Thermostat Controllers with
Dehumidification Capability
Installation Instructions
TEC3020-xx-xxx, TEC3021-xx-xxx, TEC3022-xx-xxx, TEC3023-xx-xxx
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).

Page 2: North American Emissions Compliance
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. -
Page 3: Location Considerations
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 •... -
Page 4: Installing The Thermostat Controller
IMPORTANT: Only connect memory devices to the USB port. Do not use it for charging external devices. 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. - Page 5 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.
