Solar and heating controllers
Solar controller DeltaSol® BX
The DeltaSol® BX is equipped with four relay outputs as well as two PWM outputs for the speed control of energy-saving
high-efficiency pumps. Additionally, the controller is equipped with fi ve Pt1000 sensor inputs, two analog Grundfos sensor inputs, an impulse input as well as a supplemental L`- output for the connection of an actuator.
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 extra-large display vouches for a precise visualisation of the system status. Pre-defined functions allow easier parametrisation of the system; functional additions such as a drainback option broaden the range of applications. Of course, the DeltaSol® BX is also equipped with a RESOL VBus®.
