In its standard version the IRIS-V is meant to be a ventilation computer. The IRIS-V can also be used as a heating computer. The IRIS-V is available in two different versions; the IRIS-V-5A and the IRIS-V-12A. Which version you choose depends on the maximum load that is needed. Optional, the IRIS-V can be connected to an ORION-V. If so, it is possible to make general and curve settings.
