been to a site today. old r22 system e4 and u4 fault. found condensor off put on now faulting
12v dc found being sent inside, this should be more.
did a bit of searching and found out this system had recently had a fan coil removed. went to where the fan coil was and found 4 2core cables all connected
this has a central controller on it. i am assuming there is an in and out on f1f2 and also 2 cable sgoing i assume a central controller.
do i need to tell the outdoor unit there is one less indoor, do i need to adjust the central controller to tell it one has gone
what do i need to do ta

oh and to top it off the twin split replacing the old indoor unit is over charged by approx 10 gilos. oh joy
