8.1 Automatic mode
After successful commissioning, start the Automatic mode from the device. The Automatic mode is suitable for continuous device
operation and the controller monitors the following functions:
• Maintain pressure
• Compensate expansion volume
• Degas
• Automatic make-up
Press "Auto" on the controller operator panel to start the Automatic mode. The "PU" pump and the "PV1" motor ball valve of the
overflow line are regulated by the controller so that the pressure remains constant at a regulation range of ± 0.2 bar. Faults are displayed
and evaluated. The "PV1" motor ball valve of the overflow line remains open during the adjustable degassing time as long as the pump
runs. In the de-pressurised "VG" primary tank, the system water is expanded and degassed. For Automatic mode, you can set various
degassing programmes in the Customer menu, see chapter 7.6 "Parametrising the controller in the Customer menu" on page 42 . The
controller display supplies the necessary information.
