This chapterwill describe how manual input is possible by operating the pushbuttons on the PCB and reading the feedback from the 7‑segmentdisplays.Making settings is done via the master outdoor unit.Next to making field settings it is also possible to confirm the currentoperation parameters of the unit.Push buttonsPerforming special actions (automatic refrigerant charge, test run,etc.) and making field settings (demand operation, low noise, etc.)happens by way of operating the push buttons.See also:▪ "6.1.2 Field setting components" on page 23▪ "6.1.3 To access the field setting components" on page 24PC configuratorFor VRV IV heat recovery system it is alternatively possible to makeseveral commissioning field settings through a personal computerinterface (for this, option EKPCCAB is required). The installer canprepare the configuration (off-site) on PC and afterwards upload theconfiguration to the system.See also: "6.1.9 To connect the PC configurator to the outdoorunit" on page 26.Mode 1 and 2Mode DescriptionMode 1(monitoringsettings)Mode 1 can be used to monitor the currentsituation of the outdoor unit. Some field settingcontents can be monitored as well.Mode 2(field settings)Mode 2 is used to change the field settings ofthe system. Consulting the current field settingvalue and changing the current field settingvalue is possible.In general, normal operation can be resumedwithout special intervention after changing fieldsettings.Some field settings are used for specialoperation (e.g., 1 time operation, recovery/vacuuming setting, manual adding refrigerantsetting, etc.). In such a case, it is required toabort the special operation before normaloperation can restart. It will be indicated inbelow explanations.See also:▪ "6.1.4 To access mode 1 or 2" on page 24▪ "6.1.5 To use mode 1" on page 24▪ "6.1.6 To use mode 2" on page 24▪ "6.1.7 Mode 1: Monitoring settings" on page 25▪ "6.1.8 Mode 2: Field settings" on page 256.1.2 Field setting componentsLocation of the 7‑segment displays, buttons and DIP switches:a bBS1 BS2 DS1 DS2BS3X27ABS1 MODE: For changing the set modeBS2 SET: For field settingBS3 RETURN: For field settingDS1, DS2 DIP switchesa 7‑segment displaysb Push buttons
