Utica-Dunkirk 14662313 Aquastat

The Utica-Dunkirk 14662313 Aquastat is a mission-critical single pole double throw (SPDT) immersion controller designed for precise hydronic temperature regulation. This 65-200F capillary aquastat functions as a high-limit, low-limit, or circulator controller, providing essential boiler safety control and system efficiency. Engineered for Utica and Dunkirk boiler assemblies, it features a liquid-filled sensing element that responds rapidly to temperature fluctuations within the boiler water. The SPDT switching logic allows for versatile wiring configurations, enabling the technician to either open or close the circuit on temperature rise depending on the specific application requirements. Whether you are performing a boiler burner control replacement or troubleshooting a temperature limit switch failure, this OEM component ensures tight differential management and reliable long-term operation. Its adjustable temperature range and rugged construction make it the standard choice for maintaining optimal HVAC thermal management in residential and commercial hydronic loops.

Common Installation Questions

How do I configure the SPDT contacts for high-limit protection?
For high-limit applications, wire to the terminals that break the circuit on temperature rise to safely shut down the burner once the set point is reached.

Can this aquastat be used for circulator control?
Yes, by utilizing the opposite set of contacts, you can configure the device to engage the circulator pump once the boiler water reaches the necessary operational temperature.

What is the purpose of the liquid-filled capillary on the 14662313?
The sensing bulb uses thermal expansion to actuate the internal switch, providing a mechanical failsafe and accurate temperature sensing without the need for external power logic.
