Specifically designed to regulate the operation of a solar heating system, the Delta-T Standard Series model monitors collector and storage temperatures. The controller will automatically turn pumps on or off when the right temperature differential is reached. The controller can also provide additional functions, such as system freeze protection, by recirculation and storage tank high-limit shut-off.
