En 0 Electrical wiring Wiring to external units host computer monitor panel When operating with constant input from A 3 Temperature setting Input First wire between the Indoor and outdoor units then to the separate power sources and between the indoor units and the remote controllers Then check 1 Remote control input operation control wiring is correct If wanting group control by remote controller check transmission Wire as described below Wiring differs depending on whether using a voltage or wiring For details see the installation manual of the indoor and outdoor units non voltage input Position Function Contents when Input A is OFF Contents when input A is ON 1 Remote controller rejection Operation remote controller is normally rejected 2 Central priority Operation remote controller accepted Stop by remote controller acceptable Operation stop by remote controller acceptable No operation by the remote controller To enable temperature setting from both the adaptor and remote controller set SS2 to T Factory set P P Enables temperature setting by both the adaptor and remote controller Engages last command priority I Enable temperature setting from the adaptor only The remote controller cannot be used to set temperature Next wire between the wiring adaptor for electrical appendices 1 and the indoor units For details see Wiring to indoor units Set input changeover switch For voltage input Finally wire between external units such as the host computer monitor panel and SS1 to VOLT Factory set VOLT make the necessary settings For details see Wiring to external units host 3 computer monitor paneljj NEVER apply voltage to tarminals A or A for any reason whatsoever Stop remote controller rejection Wiring adaptor KRP2A61 62 51 52 Note It is not necessary to set address No for centralized control Setting is automatic 4 Wiring to indoor units Remote controller accep tance only No operation by the remote location Remote controller acceptance rejection Temperature setting corresponds to resistance values values in the range of 0 to 135 2 Their relationship is as shown below Temperature setting C Note Input B is for forced OFF When ON stop remote controller is rejected and input 1 For zone control A is ignored When OFF even if A is ON the contents of when input A is ON are not achieved Input A must therefore be re input When operating with momentary Input from A Use a momentary input of ON time 200 mill sec or longer Position 5 For non voltage input Function Remote controller rejected Set input changeover switch SS1 to NON VOLT 6

Forced temperature shift command The indoor unit operates at 2 C higher cooling or 2 C lower heating than the set temperature In zone control operation is displayed as long as one Indoor unit is running When in the last command priority mode some units are not operation while ON In such case even if input A is ON the unit and all other units in the same zone will stop When operating with dual momentary inputs from A and B Use a momentary input of 200 mili sec or longer Position control mode as described below Function Contents when Input A Is OFF Contents when Input A is ON Max 64 groups 7
