Hi all newbie here,i have a Vaillant ecotec plus 831,i need to know how to
turn the diverter valve off,i've done it before using the buttons on the boiler
but i cant remember how
.
Also how do i get the needle on the pressure gauge out of the RED and back to showing Ten to Two
The boiler is seven years old
Thanks in advance
