The Delta-T Standard Controller is an analog controller designed to precisely regulate solar heating systems. It continuously monitors collector and storage tank temperatures, automatically turning pumps on or off when the ideal temperature differential is reached. In addition to basic operation, it offers added functions such as system freeze protection via recirculation and high-limit shut-off for storage tanks—helping protect equipment and maintain optimal performance year-round.
