Hi all
been asked to change one unit which is on a load 7 indoors to one vrv to have its own control .fitted control on wall and went to connect to indoor pcb. the control book show to connect to cn12 or cn13 . But cn13 is in use and cn12 ,what do I do with the cables I take out. Because il lose the leak between the other units any help would be great

hitatchi controllers are daisy chained at each indoor- trace the wiring from the controller to the 1st indoor, think its yellow plug in,blue plug out
, power it down.cut the plugs and joint the cables and fit ur new controller
if its a 2 pipe then the controller has to be in the same mode as the other controller
if its 3 pipe then no worries

Hi guys the indoor units are RPI-1.5 FSGE it's on a 2 pipe system I haven't got the out door model with me , yeah I have a yellow plug which goes on the control and the other end is a blue which plugs into blue connection cn13 on the indoor pcb . I tryed changing the blue dail which you chose the unit number. But ended up with F35 fault so but all back, I've seen on the control you have to cut out out jb01 I think .so let me get this right if I but the new control blue plug into the blue connection cn13 on pcb , cut the cables off the other plug which was in cn13 which is yellow , and join them on to the cable it will work and set address to unit 1

dont change the address!- the interlink cable is about 12 mtr-if it will reach the next unit then great,but if not then joint the cable, only mitsi units need controller addressing

hrmm.. our hitachi set free units in australia arent wired that way..

we are installing one at the moment and each RPI indoor unit has its own wall controller - hard wired at the indoor pcb (no blue or yellow plugs)..

The units I've got to put a control on are from the year 2000 , it was an open plan office and they want a side office made with its own control , all ducted

[AlexAlex]

For individual control of RPI-1.5 FSGE need a wired remote control:

1. PC-2H
or
2. PC-5H

[AlexAlex]

Sorry, not PC-2H.

Need PC-2H2
