Have a new installation and the piping is ran on the roof, appx 300' supply and return. Issue I'm having is chiller shuts down on-Chilled water flow Entering Water Temp. I have the chiller controlling my chiller pumps. I figure when main CW loop is satisfied chiller shuts off pumps and even though pipe is insulated it is still being effected by outdoor temp and gets colder than chiller setpoint. The heat tape on chiller barrel causes temps. To read well in excess of 160 degrees. Spoke to Trane support and they say that is normal. They also said to added a bypass control to keep pumps running, I did that but the chiller will still go into same alarm and it is not an auto reset alarm so eventually pump shuts down. Problem should go away for season as it is getting warmer outside but I know it will happen again. Wondering if anyone has seen similar issue and how it was resolved.
