I am having trouble with two 30ra30 chillers that are twinned together. I am getting mode 9 Slow Change Override and mode 26 Short Loop Override.
I believe i have a water issue. The machine has a design of 65.3 gpm and 12.6 feet head. I am get a PSI difference at chiller of 10 psi with is 23.06 ft of feed. Would that mean i am moving too much water because the heat exchanger is redistricted the large amounts of water coming in. This is a Bronze plate heat exchanger. I have been battling this problem for a while now. All help is greatly appreciated.
