I have some DX systems with danfoss fan speed conrollers RGE X3R4-7. These systems were fitted, filled and supposedly commissioned. I was initially having a problem with compressor tripping on HP as the air cooled condensers weren't comming in. I have reduced the pressure setpoint on the controller as this was still at factory setting and the fans now come in. Could anybody give me some advice on how i determine the correct pressure to set on these controllers.
Thanx
