found reoccuring error codes j4 and j7 on daikin outdoor master unit model REMHQ12P8Y1B,after
unit kept cutting out i decided to prohibit the master unit using code 38 so the slave could still run.
instructions were as follows 1 hold mode button bs1for 5seconds or more till lit.
2 press set button 38 times.
3 press return button once.
4 press set button once.
5 pressreturn button twice.
6.press mode button once.
tried instructions but it didnt program out the master unit.can anybody confirm instructions and
code 38 are correct for this unit.
i question point 6 as i thought you would exit if you pressed the mode button and return to normal operation.
