Frequently Asked Questions

An aquastat is a device used to monitor and regulate water temperature in HVAC systems, particularly in hydronic heating. It ensures that the water temperature stays within a set range for optimal system performance.

We offer a variety of aquastats and temperature control devices, including high limit controls, low limit controls, and combination controls designed for both residential and commercial hydronic systems.

Choosing the right aquastat depends on your system’s requirements, such as the desired temperature range and compatibility with other equipment. Refer to the product specifications or consult with our customer service team for guidance.

Yes, you can replace your old aquastat with a new one, but it's important to ensure compatibility with your existing system. Check the specifications or reach out to customer support for advice.

Installation typically involves wiring the aquastat to your system’s control circuit and adjusting the settings to the desired temperature range. For safety and accuracy, it’s recommended to follow the manufacturer’s instructions or consult a professional technician.
