I have an Aquacal heat pump that thas stopped functioning. Display is flashing “ECS” continuously. Control panel button presses yeild no results. Power cycles from the breaker have not solved the issue. Unplugging and replugging connections onto the microprocessor similarly has no effect. There are no apparent shorted connections or corrosion involving either the microprocessor or control panel. Serial # 1149583-F13, Model # 115AHDSBTD.
I believe in need either a new control panel or microprocessor, any idea as to which it should it be?
Are the following part numbers correct - Control panel ECS0276, Microprocessor ECP0005
Thank you very much.
