How energy efficiency is improved

Demand-based volume flow control in order to optimise energy consumption in ventilation systems. Differential pressures of at least 1 Pa can be controlled to allow minimal volume flows at the lowest duct pressure and energy consumption.

Features

• Supply and return air control for individual rooms such as offices, conference rooms and hotel rooms, in conjunction with a VAV box or a damper and flow probe.
• Pressure control in supply and return air ducts for low-noise, energy-efficient air distribution.
• Static measurement of differential pressure with MEMS sensor
• Can be used for measuring in areas with dirty or contaminated return air
• Low energy consumption and long serviceable life thanks to low-wear stepping motor
• Electromechanical torque-based switch-off for safe operation
• Extremely simple installation due to self-centring shaft adapter
• Disengageable gear unit for manual adjustment and positioning of damper
• Integrated second control loop for the following applications::

  • Duct pressure and zone control

  • Room climate regulation
• 2 x RS-485 bus interface on RJ12 and connection terminal

  • Up to 31 subscribers in a segment with SLC (SAUTER Local Communication) protocol

  • Communication within network via BACnet MS/TP
• Input and output signals for connecting:

  • Setpoints and actual values

  • Power outputs for reheaters and recoolers
  • EY-RU 3** digital room operating units
  • Analogue output
• Easy programming of the following applications using the SAUTER CASE VAV software:

  • Volume flow control

  • Room pressure control
  • Duct pressure control
• Adjustable end values of the differential pressure measuring range

  • 100…300 Pa

• Efficient control algorithm for fast control loops
• Priority control via switching contacts
• Zero point can be calibrated
