Resol DeltaSol AL – Full Kit
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. Illuminated System-Monitoring-Display ■ Up to 3 Pt1000 temperature sensors ■ Energy metering ■ Evacuated tube collector function ■ Functionality control ■ Operating hours counter ■ Intuitive operating concept ■ RESOL VBus® ■ Extra-low standby power consumption Downloads:
