Operating the push buttons and DIP switches onthe logic board13.2.1. Operating the push buttonsBy operating the push buttons it is possible to: Perform special actions (automatic refrigerant charge, testrun,etc). Perform field settings (demand operation, low noise, etc).Below procedure explains how to operate the push buttons to reachthe required mode in the menu, select the correct setting and modifythe value of the setting. This procedure can be used any time specialsettings and regular field setting are discussed in this manual (see"15.2. Monitoring function and field settings" on page 37).Setting definition: [A-B]=C; A=mode; B=setting; C=setting value. A, Band C are numerical values for field settings. Parameter C has to bedefined. It can be a chosen from a set (0, 1, 2, 3, 4, 5, …) or regardedas an ON/OFF (1 or 0) depending on the contents. This is informedwhen the field setting is explained (see "15.2. Monitoring function andfield settings" on page 37).Functions of the push button switches which are located on theoutdoor PCB (A1P)Turn on the power supply of the outdoor unit and all indoor units.When the communication between indoor units and outdoor unit(s) isestablished and normal, the segment indication state will be as below(default situation when shipped from factory).When turning on the power supply: flashing as indicated. First checkson power supply are executed (1~2 min).When no trouble occurs: lighted as indicated (8~10 min).Ready for operation: blank display indication as indicated.When above situation cannot be confirmed after 12 min, themalfunction code can be checked on the indoor unit user interfaceand the outdoor unit segment display. Solve the malfunction codeaccordingly. The communication wiring should be checked at first.Accessing modesBS1 is used to change the mode you want to access. Access mode 1Push BS1 one time. Segment indication changes to: Access mode 2Push BS1 for at least 5 seconds. Segment indication changesto:Mode 1Mode 1 is used to set basic settings and to monitor the status of theunit ("15.2. Monitoring function and field settings" on page 37). Changing and access the setting in mode 1:Once mode 1 is selected (push BS1 1 time), you can select thewanted setting. It is done by pushing BS2. Accessing theselected setting's value is done by pushing BS3 1 time. To quit and return to the initial status, press BS1.Example:Checking the content of parameter [1-10] (to know how many indoorunits are connected to the system).[A-B]=C in this case defined as: A=1; B=10; C=the value we want toknow/monitor: Make sure the segment indication is as during normal operation(default situation when shipped from factory). Push BS1 1 time; result segment display:Result: mode 1 is accessed. Push BS2 10 times; result segment display:Result: mode 1 setting 10 is addressed. Push BS3 1 time; the value which is returned (depending on theactual field situation), is the amount of indoor units which areconnected to the system.Result: mode 1 setting 10 is addressed and selected, returnvalue is monitored information To leave the monitoring function, push BS1 1 time, you willreturn to the default situation when shipped from factory.NOTICEMake sure that all outside panels, except for the servicecover on the electrical component box, are closed whileworking.Close the lid of the electrical component box firmly beforeturning on the power.INFORMATIONDuring special operation (e.g., automatic refrigerantcharging, test run, etc.) or when an malfunction happened,information will contain letters and numerical values.1 2BS1 BS2 DS1 DS2BS3X27AINFORMATIONBe sure to turn the power on at least 6 hours beforeoperation in order to have power running to the crank caseheater.INFORMATIONIf you get confused in the middle of the process, push BS1.Then it returns to idle situation (no indication on segmentdisplays: blank, refer to "Functions of the push buttonswitches which are located on the outdoor PCB (A1P)" onpage 29).
