Solar and differential temperature controllers

Solar controller DeltaSol® AL

Solar controller DeltaSol® AL The DeltaSol® AL solar controller is a temperature differential controller that offers all vital functions for a standard solar thermal system. The controller is equipped with the comprehensible System-Monitoring-Display, which visualises the system parameters quickly and easily. For data communication, the controller has a RESOL VBus® to which additional modules such as remote displays or dataloggers can be connected. The DeltaSol® AL offers e. g. a heat quantity measurement, a solar operating hours counter and can be switched between °C and °F. Operation and function control are as easy as usual. cTuVUS
