Installer Checklist

Everything the integration needs for full operation is enabled at the controller's installer level by your heating installer — the integration itself never unlocks anything and needs no access code. Print this page (browser print dialog, Destination → Save as PDF) and hand it to your installer; every item can be ticked off in a few minutes on site.
