Hi all,

I am seeking advice on how to correctly use the "EQUIP-CTRL" command, otherwise found on the Controls tab of any circulation loop. For my system, we have a vertical well GLHX with a Fluid Cooler attached to the same loop to take care of the peak cooling in the summer time. I want to fully load the GLHX before kicking on the Fluid Cooler. I have found in the DOE-2 Help an example input which I have copied and pasted into my input file. My issue is that I do not think the EQUIP-CTRL command is input correctly. I feel this way because I can turn that control on and off and my GLHX and Fluid Cooler capacities are the exact same. Does anyone have any experience with the EQUIP-CTRL command and particularly the GLHX hybrid with Fluid Cooler.

Also, I have changed some of the inputs from the above screen (Max Flow, Max Load, and Flows Through) and had no change in outcome.

Thanks in advance,
