The DeltaSol® MX is equipped with 14 relay outputs and four PWM outputs for the speed control of energy-saving high-efficiency pumps; all PWM outputs can be converted into 0-10 V signal outputs. Additionally, the controller has one frequency input, three impulse inputs as well as a range of different sensor inputs. Up to five extension modules can be connected via the RESOL VBus®.

The integrated SD memory card slot enables an easy datalogging to an SD memory card as well as a quick and effortless transfer of logged system data to a PC. The large full graphic display allows the direct display of balance and progression diagrams.

Pre-defined functions allow easier parameterisation of the system; functional additions such as a drainback option broaden the range of applications.
