Description
Description
Resol DeltaSol® AL E HE is a solar controller for standard solar systems with electric backup heating. It controls a high-efficiency pump with speed control via a PWM output and has two high-current relays to which, according to the manufacturer, an electric immersion heater of up to 3 kW (230 V~) can be connected directly, without auxiliary relays.
The electric backup heating is controlled by time and temperature. The controller has the RESOL VBus® for data communication.
