The new Drayton SHR 521 20 controller was developed for Solar Thermal Systems and can be used for domestic hot water heating. It was designed with the typical UK solar thermal application in mind and will call for back-up heating from the boiler when solar power is not available. It is very easy to set up and use. The new multifunctional display shows the collector or store temperature and simple pictograms inform the user about the function and real-time situation of the controller and the system.
