The RESOL DeltaSol AL E HE has many new features.
It is equipped with two high-current relays to which an electric immersion heater of up to 3 kW (230 V~) can be directly connected. Thus the controller manages time and temperature control of the electric backup heating.
The controller also offers a thermal disinfection function and, in addition to DHW backup heating, a rapid heat-up function which can also be activated via the RCTT remote control.
The solar backup heating suppression and the holiday mode will help save energy, the drainback option, the tube collector function and many more functions make for extra comfort. The PWM interface for a bidirectional pump as well as the VFD Grundfos Direct SensorTM input enable precise heat quantity measurement.
