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).
