The TEC3000 Series Thermostat Controllers are stand-alone and field-selectable BACnet® Master-Slave/Token-Passing (MS/TP) or N2 networked devices that provide on/off, floating, and proportional control of:

  • local hydronic reheat valves
  • pressure-dependent VAV equipment with or without local reheat
  • two- or four-pipe fan coils
  • cabinet unit heaters
  • other zoning equipment using an on/off, floating, or 0 to 10 VDC proportional control input

Models also provide single- or two-stage control of unitary rooftop units (RTUs) with or without 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 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).


  • Two configurable binary inputs
  • USB port configuration
  • Backlit liquid crystal display
  • Configurable touch screen UI
  • End-of-line switch


  • 19 to 30 VAC, 50/60 Hz, 4 VA at 24 VAC, class 2 or safety extra-low voltage
  • 0 to 10 VDC into 2k ohn resistance
  • Dry contact across terminal COM to terminals Bl1, Bl2, or COS
  • Nickel, platinum, A99B, 2.25k ohm negative temperature coefficient, 10k ohn NTC, 10k ohm NTC Type 3 across terminal COM to terminals R SEN or COS
