... I thought this book would have a bit more information than it carries....the vfd section was short and wasnt exactly correct in its information.....but it is a decent book for someone needing a basic understanding of HVAC controls and control schemes...
If you are in the HVAC or building automation field and have no understanding of controls or control schemes this is a good basic primer.
If you have some experience already in controls or commercial industrial hvac control schemes... you should pass it up.
I spent 111.00 on the book and while I wish it was more in depth I dont consider it a waste of money. I will read this book...make any notes on info Im not already aware of.... and then pass it on to one of the younger guys at work who needs some good basic information on hvac controls. ...
