Temperature controls are devices that control the operating temperature of the boiler. Hot water boilers typically operate off of temperature. Some of these controllers are also safety devices that make sure that you do not go above a certain set point and will shut down your boiler/burner in cases where you exceed that set point. Brands such as Honeywell, Dwyer, Siemens, Johnson Controls, Ashcroft are common and we stock a wide range of those brands.
