I am unable to find the right control, which can enable me to set priority order for a system with multiple heat generators. In absence of a prrority control, the generators are starting at the same time, resulting in very large surplus energy.

Dear AZ,
the control strategy you can easily change by using either different sensor positions or different temperatures for the controller.
E.g. you have a heat pump (first priority) and an electrical heater (second priority). Just switch on the heat pump as soon as the temperature in the storage tank is below 50 °C and switch it off as soon it is above 55 °C. For the electrical heater use switch on temperature 45 °C and switch off 50 °C
-> in this case the electrical heater will just run when the heat pump cannot deliver enough energy (temperature will go down)

Hope this helps!

BR Lars
