Can you give me the exact Model of the outdoor unit and the year etc...?

G50 will support remote run & fault indication by using the CN2 plug on the back of the G50.

You need a 9 wire adaptor connect cable part No PAC-YG10HA-E available from MEUK or distributors. Its about £26.00.

You will need to wire it in with a relay to interface with the BMS.

Depends of BMS branch, first you have to check if you can make an interface with this BMS with LonWorks or BAC Net, to make a preparation depending of this selection.

Have you done this as I can't get it to work!!!!!! using the circuit diagram and the cable.

G50 with PAC-YG10HA-E

The remote on / off fuction has to be activated at the G50.
Its is set in the Fuction setting page.

1/ get into the engineers mode.
2/ scroll through & select Fuction setting page.
3/ select the fuction you want to activate. In this instance you might be looking at using fuction number 6.
'perform on/off operation with level signal.

Suggest down load G50 manual for full details.
