From Water Gard:
Water GardTM is a Patented, UL Listed system used to monitor all 24V Controlled HVAC Systems for unsafe levels of condensation in the drain pans. When water is detected, Water GardTM locks out the AC System after a brief time delay to avoid false alarms. Specific Sensors are designed to fit either the Primary Drain Pan or the Safety/Auxillary Drain Pan.
