Refer to the installation manual attached to thewireless remote controller for the setting instructions.Control by 2 Remote Controllers (Controlling 1 indoorunit by 2 remote controllers)When using 2 remote controllers, one must be set to "MAIN" and theother to "SUB".Main/sub changeover1. Insert a wedge-head screwdriver into the recess between theupper and lower part of the remote controller and, working fromthe 2 positions, pry off the upper part. (See figure 18)(The remote controller PC board is attached to the upper part ofthe remote controller.)2. Turn the main/sub changeover switch on one of the two remotecontroller PC boards to "S". (See figure 19)(Leave the switch of the other remote controller set to "M".)Computerised control (forced off and on/off operation)1. Wire specifications and how to perform wiring.• Connect input from outside to terminals T1 and T2 of the terminalblock (remote controller to transmission wiring).See figure 17.2. Actuation• The following table explains "forced off" and "on/off operations" inresponse to input A.3. How to select forced off and on/off operation• Turn the power on and then use the remote controller to selectoperation.• Set the remote controller to the field set mode. For details, refer tothe chapter "How to set in the field", in the remote controllermanual.• When in the field set mode, select mode No. 12, then set the firstcode (switch) No. to "1". Then set second code (position) No. to"01" for forced off and to "02" for on/off operation. (forced off atfactory set.) (See figure 16)Centralized controlFor centralized control, it is necessary to designate the group No. Fordetails, refer to the manual of each optional controller for centralizedcontrol.ModeNo.(Note 1)FirstcodeNo. Description of settingSecond code No. (Note 2)01 02 03 0410(20)0Filter contamination- Heavy/Light= Setting to definetime between 2 filtercleaning displayindications.
