Gas Boiler 0 pressure

[Cairnsy91]

Hi, was wondering if I should turn my gas boiler off and on, it's a new boiler in a new build house, it's been going fine for a few weeks but it's flashing 0 bar on the display, the pressure gauge red needle is at 4 bar and the black is at 0.5 bar just not sure what to do before contacting the people that installed it on Monday, any advice appreciated

Need to top the system up where the guage is there should be a silver flexi attached to it with two valves open one and open the other slightly until you hear water moving / noise now watch the black on the guage 1-1.2 you can close both valves again and you should be good
