    on/off switch contact for Fujitsu ducted AC



    Hello, im installing a Fujitsu ducted A/C and would like to interface it with a webserver that remotely monitors temperatures and you can output digital outputs to turn on for example.I would like to control a fujitsu model number AOT36UNAXT. But looking at the drawings i cannot tell how this is done. Other than hacking the wall controller to bits to somhow make it press the power button on/off.

    Can anyone could suggest another way please?

    Thanks Paul.

    You must find contact indicating CLK \ USD \ BMS, it should be contact with terminal 2, when a short terminal turns off the air conditioner turns on the short opening the air conditioner (or reverse).The second way is through the communication protocol is hard to believe you can get.
