Hi
most of ac unit here are heatpump
the RV only feeded in winter so in summer most are de enrgized
i got many call of no call in these very hot days
so i found that RV are stuck in middle or in heating mode
then i energize it manually to reset it to cooling mode
and its ok
i thought the rv may get to middle or to heating mode due to wrong feed from pcb or wrongfully setting remote controll to heating mode so i disconnect RV Wires from PCB
but in some 2 ton ac
and after 3 dasys of work the RV moved to middle or to heating mode
so i tried to feeded it manually but it stuck in heating
so i will replace it
my quesion y RV move to HEAT mode even if i disconnect it wires????
