Boilers and HVAC
The selection process for incorporating electronic controls into a boiler system can be daunting and can vary depending on the application. For the simplest of applications, a basic safety relay may be all that is needed. For more complex applications,
feature rich controllers that can assist the end user in troubleshooting the heating system are a necessity. No matter what your application, specifying and designing in a controller that meets local and federal regulations is a must. Gems Sensors, manufacturer of the industry respected Warrick Line of boiler control systems, developed this article to help those within the boiler industry understand the codes that cover boiler safety controls.
The days of temperamental boiler control systems have all but passed. Nation-wide adoption of safe installation practices, regular maintenance and technological advancements are edging boilers into the category of set it – forget it. This is not to say that accidents have been wholly eliminated. They do still occur, but fortunately the introduction of critical operational and safety controls has significantly lowered the frequency.
