The digital controller is the brain of a SunMaxx solar hot water or heating system. SunMaxx offers a number of industry-leading solar hot water and heating system controllers. These controllers read the temperatures at the solar collector and inside the storage tank. When heating of the tank is needed, and the collectors can provide the heat, the controller will activate the circulator pump(s), and vice-versa. The solar controller handles all of this automatically.

Whether it be a small system, a large system, a pool heater or somewhere in between there is an SmartMaxx Controller that will pair with your system beautifully. With a large range of features and input/output options and freeze protection features, these controllers will monitor your system flawlessly. Take a look through our controllers and accessories to go with them and then choose the controller or accessory that best fits your system needs.
