What are the recommended operating pressure levels and related error codes for the system?

For the heating circuit, the pressure should be maintained between 1.5 and 2 bar. If the hydraulic pressure drops below 0.8 bar, error code 118 is displayed; below 0.5 bar, error code 118 triggers a standby state until pressure is restored. For the solar circuit, the cold hydraulic pressure should be checked and filled to at least 3 bar.

What are the required pressure settings for the heating and solar circuits?

For the heating circuit, maintain pressure between 1.5 and 2 bar (error code 118 triggers below 0.8 bar, and the system enters standby below 0.5 bar). For the solar circuit, hydraulic pressure when cold should be at least 3 bar.
