EBC 35
Modulating Pressure Control and CO Monitor

The EBC 35 is a multi-use draft or pressure controller and CO-monitor with integrated webserver and remote access used with fans and dampers to monitor and maintain a constant draft or pressure by varying the speed of a fan(s) or the position of an actuator. Typical uses are:

  • Maintain a constant draft by modulating a power venter in a mechanical draft system serving boilers and water heaters,
  • Maintain a constant draft by modulating position of an over-draft damper serving boilers and water heaters,
  • Maintain a constant duct pressure in a dryer venting system or a ventilation system
  • Control the supply of combustion air to a mechanical room or directly to a boiler(s)
  • Control and maintain room pressure

Features

  • Controls 3 air plenums (exhaust fan, damper and supply fan) via individual PID loops.
  • External bus for hardware upgrades
  • “Plug-n-Play” monitor all terminals and registers components attached
  • 0-10V signal for Edrive or actuator control
  • LCD Graphical Display and 512kB processor
  • Integrated webserver for remote monitoring, configuration and firmware upgrade
  • USB interface
  • Interlock with up to 6 heating appliances
  • Integrated safety system
  • Priority operation function
  • Intermittent or continuous operation
  • Two RS485 ports for Modbus and BACnet communication
  • Bearing cycle activation
