Are DualSun SPRING panels compatible with the Stiebel Eltron SHP-F 300 X Premium thermodynamic water heater?

Yes, DualSun SPRING hybrid panels can be paired with the Stiebel Eltron Eltron SHP-F 300 X Premium thermodynamic water heater.

This water heater does not have a function allowing the programming of time slots for heating.
In order to avoid simultaneous heating of the thermodynamic water heater and solar installation, it is possible to inform the intelligence by an electrical signal to give priority to free solar heating.
It is then necessary to link the DualSun solar regulation to the electronic board of the thermodynamic water heater.

Setting the thermodynamic water heater

The device is designed to be able to assign a distinct sanitary hot water value ("temperature 2") according to the external signal.
Set the set temperature 2 to 35 degrees Celsius.
This inhibits compressor engagement when solar regulation transmits an active signal.

 

Note: Increase the temperature 2, if this setting causes discomfort.
