The controller has the following I/O:

  • 2 regulator (0-10V) outputs to control VAV etc. Fully configurable with set-points for CO2 and temperature level.
  • 2 relay outputs used to control heating and cooling sources or ventilation on/off, based on temperature or CO2 level.
  • 1 on/off input to use alternate controller scheme based on occupancy, night switch etc.
  • 1 digital RS-485 Modbus line for BMS communication and set-up

The VAV Regulator set-up program is a simple, visual and self-explaining Windows applications that enable flexible configuration of all outputs. VAV Regulator Kit (special USB RS-232-3V interface cable and software) can be ordered at Orders and Quotes

Default settings from factory for Output A (OUT A) is to regulate over 4-10V based on highest value of
21-23oC og 700-900 ppm CO2 (and closing to minimum ventilation, 0V output, below 18oC).

Installation of Demand Controlled Ventilation doesn’t need to be complicated.
