Help with New Vaillant Boiler not staying on

Can I please check- I need to press white Arrow once til it has 2 orange lights and says II ? Do I need to turn anything off or just press it while pump and boiler on?
Thank you,
Irina
Yes press the button until there are 2 lights on, don’t think you can do it without the pump running, so yes leave everything on with a demand.
 

We recommend City Plumbing Supplies, BES, and Plumbing Superstore for all plumbing supplies.
