Vaillant ecotec plus 837 pressure gauge on red

Hello, I have a Vaillant EcoTec plus 837, since my decorators took 2 radiators off and emptied the water from the radiators to paint behind the radiators both the radiators are now cold. Also the pressure gauge is on red and should be in the grey area. Please can you tell me how to get the pressure gauge back to grey. Thank you

What's happened is after taking the radiators off to decorate, the system pressure has dropped due to removal of system water inside the radiators. The reason the rads are cold now is because they will be full of air. On the ecotec there should be two knobs underneath the appliance which is called the filling loop. It lets mains water into the system hence topping up the pressure. Easily solved and not a huge problem.
