The AquaGuard AG-3180E micro-electronic condensate sensor is mounted directly in the primary drain pan. According to the company, this makes it a viable solution for commercial package units. The bonus secondary sensor features water detection LED and easily installs in the metal or plastic secondary drain pan. Both sensors continuously monitor any condensate overflow in the primary and secondary drain pans and automatically shut off the system and activate an alarm if any overflow is detected in as little as 1⁄16 inch of water in either drain pan.The AquaGuard AG-3180E
