Valiant ecotec plus 831 high/low fire settings

[Inverness]

hi guys, came across my first valiant combi. I couldn't figure out how to get high fire and low fire to check my ratios and co2.
There wasn't a manual.
Any advice?
I'm used to Worcester boilers.

Use the menu to enter installer level
Code 17
Max and Min
Easy once you have done it once

Installer level
Code 17
Press + twice and your in “p”codes.
P zero is high p 01 is low.

Thanks Scott. Is it me but there's too much electronics digital buttons. I've looked at the manual and I still can't find how to set it to high n low fire?
thanks

I was close I managed to get to the installers level. And it displayed from 00 -80 odd. I stay this where I select 17 then I'm in the p codes?

Yes. It will take you to d codes first. Press + to get to p.

P1 is max rate and P2 is mine rate.

P.0 is just for purging the boiler

Please note that the minimum setting cannot be adjusted as this is auto adjusted dependant on the maximum being set correctly.
To set the maximum, locate the small black cap at the top of the gas valve and gently remove it to reveal a brass throttle.

Clockwise decreases the co2 and anti clockwise increases the co2.

Sorry
I can test a vaillant with my eyes shut. But should describe it to someone else, before I’ve had a drink!
