Just wondering if any one has used these controllers. Looking at using the ECO3 to on a copland used running a walk in freezer room. From what I've read they seam to be on the money, just wondering if any one has had any first hand experience.

cheers

Im not a big fan. Have seen them on some AC units and the ultimate result was the rooms temps started to fluctuate. It basically saves money by stopping the compressor from running by using algorithms and measuring the average start/stop times and then starts to shave off compressor operating time based on these measurements. (this is how I understand that it works)
Money better spent on upgrading to something like a EEV.
My opinion only.
