New software version for Priva Connext enables modulating control of LED lighting

Priva recently launched the new software version 914 for the Priva Connext climate computer. Connext 914 brings you attractive new functionalities, such as the option for modulating the control of LED lighting, an energy-saving cascade control for customers using multiple Priva Vialux systems, and new options for connecting external sensors.

Modulating control of LED lighting and energy savings
Connext 914 enables modulating control of LED lighting and helps you to save energy. With this new option, it is possible to automatically adjust the amount of grow light to the available sunlight (PAR or solar radiation), which is cost-free. By linking the modulating lighting strategy to your electricity management, heat management, and screen control, you can create the perfect balance between the right amount of light for the crop and your energy consumption. It’s even possible to link electricity management to the balancing market.

Cascade control for Priva Vialux
If you use multiple Vialux systems to disinfect your irrigation water, Connext 914 contains an interesting improvement. Previously, the number of Vialux systems to be switched on was determined by the amount of ‘dirty drain water’ in the silo. In the new version, the Vialux systems are switched on based on the required amount of clean water. This ensures that the required amount of clean water is present at the right time. In addition, the new cascade control contributes to energy savings because the systems switch on and off less often.

Connecting additional sensors more easily
In addition to the standard sensors in your Priva systems, additional sensors can also be connected to it using a customized module. This was limited to a 0-100% measurement, an alarm measurement, or temperature measurement. With Connext 914, this set has been expanded by the following sensors:

  • EC (Electrical Conductivity)
  • pH
  • Water temperature
  • Air temperature
  • Relative humidity (RH)
  • CO2
  • Radiation
  • PAR (spectrum)
  • Position
  • Power (data bus only)
  • Volume (data bus only)
  • Universal IPT measurement (no unit, no data bus)
  • Universele IPT-meting (geen eenheid, geen databus)

Security and reliability of systems
Besides providing access to the latest functionalities, a software update also ensures that your systems will meet the latest updates with regards to safety and reliability.
