i have an air cooled condensing unit "ACZ070" with the microtech II processor in it. this is a three year old unit that was just installed. the factory start up was completed and the next day the processor let the smoke out. after the factory rep installed the new processor,i tried to raise my condenser fan setpoints and it seems to be set up for "read only". does anyone have a clue how to unlock the controller? any help is appreciated.
