ᐅ Helios Controlled Residential Ventilation System Commissioning Service

Some time ago, upon my request, Helios informed me that they can also take care of commissioning the ventilation system after the installation is completed. However, I have now learned that this service can only be commissioned through wholesalers. I purchased the components through online shops and installed them myself.

Is it only possible to arrange the commissioning service through wholesalers? Has anyone perhaps installed the system themselves and then managed to get the commissioning service directly from Helios?
