What should the pressure reading on a Thermecro Solar System be?

For the Thermecro Solar System to operate correctly in the context of a pool interface, the valve should be showing a pressure reading of approximately 0.4 Bar on the manometer. This precise pressure would help in maintaining the right flow rate and operational efficiency for the system, ensuring that the solar heating functions optimally. Always consult the system's manual or a professional technician to ensure correct installation and maintenance.
