Hello everyone, this is my first post. Hopefully I have put this in the right section, if not, please redirect me.

Here is my question -- I am doing start up on a Hussmann Protocol for a smaller sized market. I have started these up before, but they used to use contactors for the electric defrost from the CPC boards for the coils. Now they are using a new technology I have not seen before. It is called Powerlink, and it looks to be switching polarity to run the defrost, I could be way off, I am really not sure.

Was hoping someone has had some experience with this.

Thanks,

Ryan
