Mend Vaillant Reduce Water Pressure

How do you reduce The water pressure?

I would like to reduce the pressure in my Vaillant Eco Boiler

Easiest safest way, is to bleed a radiator until the pressure is what you want. But do it when the system is cold, otherwise, when it cools down, the pressure will drop below required.
