Excel 10 smart VAV controller

  • Product Info
  • Literature


W7751B,D & F VAV II Controllers provide pressure independent or dependent air flow control and series and parallel fan control with one and two duct applications. W7751H & J Smart VAV Actuator are VAV Box Controllers with a ML6174B Actuator.


  • Uses Echelon® LonWorks® protocol.
  • W7751B,D,F use Free Topology Transceiver (FTT) networks and are compliant with VAV device object type number 8010 functional LonMark® profile.
  • Energy saving setpoint reset for electrical demand limit control.
  • Actuator included with W7751H mounts directly onto VAV box damper shaft and has up to 70 lb-in. torque, 90 degrees stroke, and 90 sec.
  • Timing at 60 Hz.
  • High speed 78 kilobit communications network.
  • Capable of standalone operation, but uses E-Bus network communications.
  • Easy user-access to the network communications jack.
  • Uses enhanced microbridge-type airflow sensor with dual integral restrictor design.
  • Easy user-access to airflow sensor inputs.
  • Provides Proportional Integral Derivative (PID) temperature control.
  • Designed for pressure independent Variable Air Volume (VAV) control.
  • Floating hot water and three-stage electric or modulating hot water heat.
  • Provides nonlinear floating algorithm for velocity control loops.
  • Individual zone pressurization for supply and exhaust control.
  • Factory configured via EEPROM with critical user parameters default values.
  • Motion sensor interface for enhanced energy savings.
  • Supports Terminal Regulated Air Volume (TRAV) concept.
  • Pressurize and depressurize, night purge, and morning warm-up sequences supported.
  • Wall module options for sensor, setpoint and bypass.
  • Software selectable limits on remote setpoint adjustments.
  • Three integrated 8 bit pipelined microprocessors running at 10 MHz.
  • 14 bit A/D converter.
  • 32K by 8 ROM/PROM, 512 bytes of EEPROM, and 2048 bytes of static RAM.
  • W7751D,F mount to a standard 4 x 4 in. and 5 x 5 in. junction box or snapped to 35 by 7.5mm EN50022 DIN Rail.
  • Subbase provides the slotted hole pattern for the R7450 series IRC devices (118x87 mm).
