Control equipment with proprietary software

The entire range has integrated control equipment with software developed by us. We use Siemens Climatix hardware. The control equipment offers over 100 standard features to choose from so that you can optimise according to your needs. Air flow rates and temperatures can be optimised easily. The units can be connected to the web, IV Produkt Cloud or a parent system (BMS) via multiple communication protocols.

Project-specific electrical and control diagrams are included in the delivery. The unit has been function-tested and is ready for commissioning.
