Group Control for S Series
02 October 2012
When connecting multiple S Series (SUZ) single split systems on to one controller,
please follow the below instructions.
Scenario: 2 x PLA RP 71BA Cassette Units with 2 x SUZ KA71VA Condensing units
with 1 x PAR 30 MAA Controller.
The PAR 30MAA needs to be connected to the master cassette unit as standard.
Connect a MAC 3971F adapter to the SLAVE UNIT by plugging the red plug from the
adapter on to CN105 on the SLAVE UNIT indoor PCB.
Installation of a 2 core cable (1mm screened cable) is required to connect the MAC
3971F of the slave unit on to the master unit. This is done by connecting terminals A
and B from the MAC 3971F to the remote controller terminals on the MASTER indoor
Unit.
A&B
As the MASTER UNIT is already addressed as “00” you will need to set an
address for the SLAVE UNIT on the MAC 3971F by locating SW501 and
pushing Pin 1 (up) into the ON position.
