Was called out to a problem this morning, "the air conditioning not working". When i got to site i found power to 2 of the condensors (there are 3 condensors feeding 6 indoor units) with no power to the 3rd.
Went upstairs to the control panel where the controllers where mounted and found a breaker tripped for the condensor.
I turned the breaker back on and put all of the controllers into cooling 19DegC whilst holding the sensor on the return air of each indoor unit but none of the outdoor units kicked in.
I went to the outdoor unit and on the back of the cover it said to move DSW1 switch1 to on and this would put it in emergency cool..... but again nothing kicked in.
I have power on each of the indoor and outdoor boards but they are the new hitatchi's which i haven't had much dealings with.
How do i put the controller on test mode or is this not possible? The model number of the controller is PCP 2HT and the condensor is an Hitatchi RAS8HRNM, any help would be appreciated.
Thanks guys
