A-MATIC

The Loop model is a two-speed fan, designed for continuous operation. Speed change can be achieved manually or automatically, depending on the configuration. The speeds are changed manually only on fans which have a terminal block (by means of a wall switch) or via a timer (the higher speed is turned on with a switch while the speed is reduced automatically after 30 minutes). Automatic speed change is available on fans fitted with a humidity sensor (H) and motion detector (R). The fan increases its speed when the humidity level exceeds 70% (H) or after some movement in the room has been detected (R). The speed is reduced automatically when the humidity level is below 70% (H) or when the last movement has been detected (R) – in either case the speed reduction occurs 15 minutes after the event.
