What is the correct system pressure for the Greenstar 1000 and how do I check it?
The system pressure should be adjusted to between 1.3 and 1.7 bar. You can check the system pressure via the HMI screen by pressing the return button or the up/down arrows. If the pressure reads less than 0.8 bar, you should re-charge the system. (Page 6)
