Hi

Can anybody advise where I can find info on the (on/off) remote control of Hitachi indoor cassettes (RPC) via stand alone Energy Management Systems ?

Sorry Steve, can't seem to track down RPC on the Hitachi site, any other numbers?

Hi Brian

Unit is badged as Hitachi RPC-6.0 FSNE.. Hitachi have sent me some 3 pin pcb plugs complete with cabling but no instructions as to where to fit them (on the indoor unit) or how to connect them..We interface with most manufacturers and have no problems with interfacing with Mr Slims..I have trawled the Mitsy site and am struggling BIG time to find info

Regards
Steve

Register on the hitachi site and download the tech manual for this model, all systems have connections to remote on off the units? is it just on/off you want?

Fitted some to RCI units a few weeks ago.

3 wire addaptor same as Mitsubishi.

Indoor unit circuit board CN3

pin 1 green
pin 2 yellow
pin 3 orange

Yellow / green make circuit = system on
Yellow / green open circuit = system off.

But you need to activate the remote on/off fuction at the remote controller with an input setting & for that you really need the service manual for the full set up instructions.
