Re: [datacenter] AC settings

Datacenter temperature is open for speculation :) but I believe
that the Bellcore standard is < 71F. I don't have the docs
in front of me.

Now, I'm not saying that's what you should use, but I typically
take the Bellcore recommendation, and adapt it to my needs, wants,
and $$$.

Remember, every degree is going to cost you power. Also, did you get
humidifiers with your units? That's where people will complain i.e.
if it's too wet, or too dry.
