Aqua-Hot Conductive Fluid Level Switch - ELX-800-005

The Aqua-Hot Conductive Fluid Level Switch is a direct replacement part used in Aqua-Hot hydronic heating systems designed to monitor the heater's coolant (antifreeze) level and communicates with the system's control circuitry to detect low-fluid conditions. By providing reliable coolant level monitoring, it helps protect against overheating and potential damage to critical heating system components. Recommended OEM Replacement Fluid Level Sensor FRU - ELE-800-006-FRU Important Information Low Coolant Level Detection – Monitors the antifreeze level within the boiler tank and supports the system's low tank-level cutoff protection. Conductive Sensor Design – Uses a conductive probe to detect coolant presence and works with the separate inline amplifier circuit (ELX-AMP-005) to communicate fluid-level status. Genuine OEM Replacement – Designed for proper fit, compatibility, and reliable performance in compatible Aqua-Hot hydronic heating systems.
