The DeltaSol® AL solar controller is a temperature differential controller that offers all the vital functions for a standard solar thermal system. The controller is equipped with the comprehensive System-Monitoring-Display, which shows the system parameters quickly and easily. For data communication, the controller has RESOL VBus® to which additional modules such as remote displays or dataloggers can be connected. The DeltaSol® AL offers energy metering, a solar operating hours counter and can be switched between °C and °F. Operation and functionality control are straightforward.
