Ventilation control units
Power supply units coordinate when windows in your window ventilation system need to open or close. In smoke and heat extraction systems, the emergency power supply unit controls the smoke and heat extraction in case of fire. The use for daily natural ventilation is a welcome side effect of smoke and heat extraction systems. Ventilation technology is controlled by the vent switch, further sensor information (rain, wind, air quality) or the timer. When smoke and heat extraction is needed, the control is managed via SHEV buttons or automatically, via smoke heat detectors.
