RESOL
Differential Temperature Controller
DeltaSol BX Plus - Full Kit

The DeltaSol® BX Plus controller is equipped with 5 relay outputs, as well as two PWM outputs for the speed control of energy-saving high-efficiency pumps. Additionally, the controller is equipped with nine Pt1000 sensor inputs and connections for two digital Grundfos Direct Sensors™. 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 visualization of the system status. Pre-defined functions allow easier parametrization of the system; functional additions such as a drainback option broaden the range of applications. Of course, the DeltaSol® BX Plus is also equipped with a RESOL VBus®.
