Burnham Boiler 80160703 Aquastat

The Burnham Boiler 80160703 Aquastat is an essential temperature-actuated control designed for high-limit or operating control applications in hydronic heating systems. Specifically configured as an immersion-type controller, this component features a Single Pole Single Throw (SPST) switch logic with manual reset functionality. This ensures system safety by interrupting the burner circuit if the boiler water temperature exceeds the designated setpoint. Designed for seamless integration with Burnham Alpine boilers and other compatible HVAC systems, it operates within a precise 100-240°F temperature range. The immersion well design facilitates rapid thermal response times, allowing for accurate monitoring of water temperature within the heat exchanger. This HVAC high-limit controller is constructed for long-term reliability in specialized residential and commercial boiler assemblies, providing the necessary failsafe to prevent overheating and potential equipment damage. Proper boiler temperature control is critical for maintaining peak efficiency and preventing excessive thermal stress on the pressure vessel.

• Precise Thermal Monitoring: Provides a broad 100-240°F adjustment range for versatile system calibration.
• Manual Reset Safety: The redundant safety circuit requires physical intervention after a high-temperature trip, ensuring the underlying fault is addressed.
• Durable SPST Switch Logic: Built to handle the electrical load requirements of standard burner circuits without premature contact wear.
• Direct OEM Compatibility: Specifically engineered as a replacement part for Burnham systems, reducing diagnostic and installation time during service calls.
• Fast Response Immersion Sensing: Minimal thermal lag ensures the high-limit trip occurs immediately upon reaching the threshold.

Is this aquastat a direct replacement for all Burnham Alpine series boilers?
This part is the designated oem replacement aquastat for several specific Alpine models. Technicians should verify the part number in the specific boiler’s manual, as variations in mounting depth and junction box clearance can occur between different series.

What is the primary difference between a manual reset and an automatic reset aquastat?
The manual reset on the Burnham 80160703 acts strictly as a safety high limit. Unlike an operating control that cycles the burner to maintain temperature, this device locks the system out until a technician inspects the boiler, providing an essential layer of protection for the hydronic loop.

How do you wire the 80160703 into a standard burner circuit?
The SPST immersion aquastat is typically wired in series with the gas valve or the burner primary control. When the temperature exceeds the setpoint, the internal contacts open, breaking the circuit and terminating the heating cycle until the reset button is engaged.
