I am looking at the IntelliFlo VSF 011056 pumps but have a question. We plan to control the pump speed via their RS-485 link. They are TEFC (Totally Enclosed Fan Cooled) motors. When you run the pumps at lower speeds, their cooling fan also runs slower.
Is there ever an issue with them overheating at lower speeds? Do they have overheat shutdowns? Does the RS-485 bus provide any data on temperature?
