I am working on a trane chiller model RTHD UB1F XH0U AC1A BRAL D1A2 RALA VXQA EXAA XXY1 46FG UA5X XXXX DX and have a question about the chiller not loading up to full capacity. It will only run between 70 and 75% of RLA
Now its for a school and they have two of the same chiller. They alternate between the two and never run both at the same time.If I run the other one it will load up to 100% capacity and step down when its closer to set point and maintain it. Now if I run the other one in question it only goes to 70 to 75% RLA. Any reason as to why? I have showed a fault in the history for well over a month and it was a loss of water and thats because the school district killed the pump. If you need any other info to help me out I can provide it hopefully.
Thanks in advanced.
