SOLARFIRST function
If the solar pump switches on, the Sol Plus controller will send a signal to the boiler
controller. The boiler controller will then reduce the set temperature of DHW
heating by 0 - 30 K (adjustable).
Result: Priority of solar heat
If there is not enough solar energy, the solar pump will switch off and the boiler is
set to its “normal” operating mode.
The solar controller and the boiler controller work together in order to increase
the solar yield and to decrease gas and / or oil consumption.
Only with standard solar system 1.
