The DeltaSol® AL E HE controller is especially designed for standard solar systems with a high-efficiency pump and an electric backup heating.
The heater can be directly connected to the controller without the need of auxiliary relays
It is equipped with a PWM output and two high-current relays to which an electric immersion heater of up to 3 kW (230 V~) can be connected.
.
For data communication, the controller has a RESOL VBus®.
