how to range rate a green star compact

[@tomstrutton4351]

Hands down my favourite boiler guy on here…. Straight to the point…not turning a 2 minute video into 40 minutes

Great video if we did more of this we would be okay with gas boilers

What is Worcester heat exchanger cleaning tool Geoff??? Not the rasp but the silver one please 🎉🎉

[@PatFord-f3x]

Very informative. And such a lovely face haha

Hi Geoff, is there some green star compact models you carnt range rate as some dont have the compatible software any help is most grateful

[@raul835]

Some have the chip that you can change on the board that is in plastic bag inside boiler casing.. think the chip halves the KW outage of the boiler. So a 30kw one goes to 15kw.

All cdi and si compact software is not the same the difference between the models are the HCM heating control module and the flow regulator later models had a different size water to water plate heat exchanger in the 15 years I work for Worcester I never come across a CDI compact with different software, but the si has different software I think it’s because they were a cheaper alternative to cdi compact Worcester as far as I’m aware did not put this in your manual so the manual you have with your SI would be the same as the CDI compact I hope this is helpful

@raul835 What are you describing? Is the code plug which come with the green star junior which reduce the heating kilowatts not the CDI compact

[@plumbertime]

I’ve had some that don’t give you the option to adjust the max output. Was told it was a software thing

My compact si goes straight to 3.3d menu option which is minimum output… no option for 3.1a - any idea why? Thanks

[@geoffreyneedstraining5856]

The honest answer is I have not come across this on a SI, but I will find out for you.😉

[@raul835]

Does range rating affect the readings we're looking for on analyser?

[@geoffreyneedstraining5856]

The answer is no if you were analysing the boiler then you would be putting the boiler in to chimney sweet mode #high and low fire mode to get your readings all you’re doing is range rating the heating output
