OPTIONS

  • High-efficiency EC blower motors:
    • Intelligent Constant Volume (CV) EC motors for ultimate airflow control
    • Entry-level Constant Torque (CT) EC motors provide efficiency at a value
  • DXM2.5 Advanced Communicating Controls:
    • Includes all of the CXM2 control features
    • Dial in desired airflows for (CV) EC blower motors
  • vFlow® modulating water flow:
    • Modulates water flow to maintain a water-temperature differential
    • Changes the operation to modulate to a leaving-water temperature during extreme entering-water temperatures
    • Provides ultimate variable water-flow control
    • Functionally operates as both a water-flow regulator and a water close-off valve
  • Two-way motorized water valves that prevent water flow through the unit when it is not in operation, increasing system pumping efficiency (fail-open or fail-closed options)
  • Three-way motorized water valves that allow continuous water flow through the water loop, reducing pressure drop when the unit is not in operation (usually applied on the top floor of a system)
  • Hybrid Hydronic Heating
  • 2-inch filter rail to support higher indoor air-quality filters
  • BACnet, Modbus, and Johnson Controls N2 compatibility options for Building Management Systems (BMS)
