Solar control technology

 

Solar thermal systems are operated and controlled by solar controllers. These are the “brain” of any forced circulation solar installation. The controllers measure the temperatures of collectors, stores and other heat generators. By evaluating these measurements, hot water distribution is efficiently controlled by means of pumps and valves. Our solar controllers provide all the functions required to control any type of solar installation.
