The RESOL DeltaSol® MX is a system controller of the latest generation and offers almost boundless possibilities in planning and controlling solar thermal systems. It is equipped with 14 relay outputs and 4 PWM outputs for the speed control of energy-saving high-efficiency pumps. Additionally, the controller has three impulse inputs as well as a range of different sensor inputs. Pre-defined functions allow easier setup of the system; functional additions such as a drainback function extend the range of applications.
