NOTES:
1.Pickingupsignalwithin10secondsafterpowersupplyisturnedONisnotpossibleduetoinitialization
ofthecomponents.
Donotchangethesignal(ON/OFF)inthisperiod.
2.WiredControllerisrequiredforthisfunction.
3.Ifmultipleindoorunitsareconnectedtothesamecommunicationcableforwiredcontroller,inputthe
signaltoanyoftheseindoorunits.
4.Whenthecommunicationcableisnotusedinthetwin,tripleandquadcombinationsforsimultaneous
operation,inputthesignaltothemainindoorunit.
