Applications
The networked TEC3000 Series Thermostat Controllers are stand-alone and field-selectable BACnet® MS/TP or
N2 networked devices. Wireless networked models of the TEC3000 Series Thermostat Controller are also
available. Proportional Fan Coil and Individual Zone Thermostat Controllers 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.
The wireless models are compatible with the WNC1800/ZFR182x Pro Series Wireless Field Bus System that
enables communication with a building automation system (BAS). 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. For Single-or Two-Stage Economizer Thermostat Controller models, only the single-speed fan
configuration is supported. For TEC3x1x and TEC3x2x models, multiple fan configurations are supported for fan
coil equipment types, as follows:
• 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).
