Quick question as I am confused: commissioning

[GaryBixhall1984]

Hi all, first off thanks for being a great resource. I have just finished installing an Adroit D96 and it's working great. I used the forum more than a few times to work everything out, thanks!

 

I am now commissioning and have the designed rates from a company. I am assuming these are the rates when the system is in boost mode, is that how these commissioning figures are supplied normally?

 

Also in Part F I see 0.3l/s is required per m2. So my house is 110m2, so need around 34 l/s extract and same for supply. Is this the constant ventilation or on boost, I think it's constant? It just seems very high.

 

I know people on here dial settings down from Part F but just want it right at commissioning time.

 

To get the designed values and satisfy Part F my system is running at 60% extract and same supply. Does that sound high? 

 

Thanks and appreciate the help in advance! Gavin

Thanks for that - still not super clear but I'm happy with all the numbers I am getting and its perfectly balanced so I guess I am good to go!
