Aqua-Hot Fluid Level Capacitance Switch - ELX-800-003

The Aqua-Hot Fluid Level Capacitance 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.

Important Information

• Low Coolant Level Detection – Monitors antifreeze levels within the boiler tank and helps protect the heating system from operating under low-coolant conditions.
• Capacitance Sensor Design – Uses capacitance-based sensing technology to detect coolant levels without relying on a traditional mechanical float switch.
• Genuine OEM Replacement – Designed for proper fit, compatibility, and reliable performance in Aqua-Hot hydronic heating systems.
