3 Mitsi's on 1 controller

[marc5180]

I've just reinstalled 3 Mitsubishi PLA-P5AA that are a few years old but i'm wondering how do i connect the 3 indoor units onto the one controller since they are all in one area?.
The controller is a Par 20maa.

I've also fitted 2 brand new ducted Daikin Fan coils FBQ140C7VEB that again both need to be on 1 controller.

Is this done by just linking P1 and P2 between the 2 fan coils or do i have to go into the setttings and change it to 11-02 like you would on a muti?

Far as i remember loop controller to each indoor, address each system and off you go.

What I have understood about Mitsubishi with ma remotes you do not need address settings - it is done by the controller automatically (it sees how many units and attaches the addresses).

Connect the PAR20 to all 3 indoor units with a daisy chain on 12v dc remote control terminals.
Set the outdoor unit refrigerant address with SW1 to
00 1st unit
01 2nd unit
02 3rd unit

Using this set up the outdoor units will start up one at a time & not all together.

Yes mate. Daisy chain however many units you want and then at the start or end of the chain, wire in another cable for the remote.
