Yes, this is possible with a 24vDC system. You would need a 5A panel and a retractive switch, and then adjust the settings in the control panel.
No, Sertus doesn’t currently supply this.
We don’t supply self-cleaning glass at the moment.
Yes, we can supply ladders for our RAH-R and RAH-C models. However, please note that installing a ladder will reduce the free vent area by approximately 0.4m².
