Hi, I am currently at school learning the basic of refrigeration.

My class is advanced in the formation, we know the basics (start-up, installation, critical charges, thermodynamics, electricity basics, electricity 2, compressor, Superheat ETC ETC)

Now we are doing all kind of troubleshooting on Heat-Pumps and A/C.

I was always in the first tier of my class mostly because I was studying home and had a good work ethic. But now, I am struggling whit the 24v and every trouble related whit electricity.

I would like to know if there are any documentation that could be great to read regarding Electricity or climatisation troubleshoot.

Thanks in advance

BTW my english is not that great, it is my second language
