The SEC-Touch from SEVentilation allows an „individual“ control in pairs of up to 12 fan drives with six ventilation levels each. No matter if you choose intermittent ventilation, a time program with up to 5 switching times or the snooze function, with the 3.5’’ multicolor TFT touch control element this is easily possible. It also automatically counts the hours of operation and warns well in time if a filter replacement is needed.
