Hello everyone
I've got a couple of McQuay WHS 248.2 water-cooled chillers.
On one of them there is a controller issue where the chiller will start even if there is no water flow. The differential switches are working properly and the controller can see the change of state of the input when the flow is made or removed.
I think that the program in the Carel has become corrupted. Has anyone elese ever had this issue? Any suggestions?
Any help greatly appreciated.
