Repressurising a Viessmann 200-W with 200 H01B Controller

[rarem]

How do I see what water pressure this boiler is at? There doesn't appear to be any pressure gauge for me to determine when it reaches 1 bar or not.

(The full story: the boiler cut out with an F2 fault, which I believe is a system pressure fault. But without a pressure gauge on this unit I can't see any way of determing what is the current and correct pressure! I also have to reset it when I find the reset button 'R', whereever that is!?!)

Left and right from the controller on your boiler there are two sliders...
The left is for the pressure gauge and reset button...
The right is where the on/off switch is located...

I've worked this out so thought I'd post to help others here. Either side of the main display panel there are two (well-hidden!) sliding doors that slide back to reveal the pressure gauge and the 'R' reset button. It's then just a case of topping up the water pressure using the filling loops. The pressure has to be between 1 and 2 bars, mine was at zero.

After topping up the pressure and then pressing the 'R' button everything is working fine.

Sorry Wally, I didn't see your reply before I added mine. Many thanks for your reply! I appreciate it.
