    we recently installed a climatemaster 30 and unit started correctly the first time on a call for cool, after unit was turned off it was tripping on high head pressure. found out the AO-2 pin was set for variable speed. set switch correctly to modulating and unit runs fine. My question is on the intial start up why did the valve open when pin setting was incorrect? Thank you
