Go-Anywhere Wireless Terminal Equipment Controller for Any HVAC Equipment

Product Features:

  • One Device to Rule Them All: 11 interface ports and a high-contrast screen for control of plant equipment, terminal units, dampers, valves, lighting circuits, OEM or third-party sensors, and more.
  • Constant or Variable Volume & Temperature Systems (CAV or VVT): increase comfort and energy efficiency with control at both the damper and the air handler to redirect air where it is needed the most.
  • Variable Air Volume (VAV): power up and pair via Bluetooth in seconds, select a pre-written sequence of operation, and never deal with wires or manual programming ever again.
  • Predictive Control and Outside Air Optimization (OAO): extra-long-range 900 MHz wireless network to and from the cloud every 60 seconds plus standalone emergency operation.
  • LCD Display: faster pairing, connecting, testing, and troubleshooting means lower costs and more consistent installations, all without voltmeters, programs, application licenses, or laptops.
  • Long-Range Antenna: transmits and receives encrypted data over a secure and self-assembling wireless mesh network, with sophisticated firmware to adapt to disruption and always find the least-time path to the CCU.
  • Smart Damper Control: two analog points allow for precise control of modulating damper actuators, all with local mounting and powering via low voltage 24v AC/DC at terminal equipment.
  • 24V Input & Output Daisy Chain Power: designed to be a simple and powerful general purpose terminal equipment controller, allowing 24v AC pass through to daisy-chain up to 24 devices.
