The launch of Svara marks the next generation of unitary fans. Home owners have complete control of their indoor air through an intuitive App designed to give them flexible options on how to run the fan. Giving home owners this control has the added benefit of removing the need for multiple returns to the property post installation should the fan not be set up quite to the householders’ liking. For example the humidity setting being too sensitive. The home owner can simply log on to the App and change the setting themselves. Bluetooth controlled extraction fan with variable speed lo-carbon motor. Offering total user control and flexibility with silent mode, purge option and intelligent light sensor with over-run timer. Can be continuous or intermittent with timer and humidity functions. Simple set up for installers with no switches or jumpers involved.
