The FST-77A is a 7 day fused spur time switch for controlling combination boilers, storage heaters, convector/panel heaters, towel warmers, water heaters, washing machines and dish washers. It replaces a fused spur box and mounts directly onto the wall where the mains power socket would normally go. The panel heater / radiator / towel warmer etc can then be direct wired to it to allow for 24 hour / 7 day timer control. Please note: If using with an electric towel warmer, the timer must be situated outside of the bathroom on the other side of the wall. It is not splashproof.
