Monitoring function and field settingsThe operation of the outdoor unit can further be defined by changingsome field settings. Next to making field settings it is also possible toconfirm the current operation parameters of the unit.The setting can also be performed via the PC configuration software.Below relevant Monitoring mode (mode 1) and Field setting mode(mode 2) settings are explained in detail. How to access them, how tochange the value of the settings and how to confirm them is explainedin 13. Making field settings on page 24. In that chapter, an example isgiven on how to make a setting. It is advised to check this procedurebefore accessing, checking and changing below settings.Once the default situation of the segment indication is confirmed (see13. Making field settings on page 24), the mode 1 and mode 2 can beaccessed.Making settings is done via the master outdoor unit.15.2.1. Mode 1Mode 1 can be used to monitor the current situation of the outdoorunit. Some field setting contents can be monitored as well.Below the settings in mode 1 are explained.[1-0]= shows whether the unit you are checking is a master, sub 1or sub 2 unit• No indication=undefined situation• 0=outdoor unit is master unit• 1=outdoor unit is sub 1 unit• 2=outdoor unit is sub 2 unitMaster, sub 1 and sub 2 indications are relevant in multipleoutdoor unit system configurations. The allocation of whichoutdoor unit is master, sub 1 or sub 2 are decided by theunit’s logic.The master unit must be used to input field settings inmode 2.[1-1]= shows the status of low noise operation.• 1=unit is currently operating under low noise restrictions• 0=unit is currently not operating under low noise restric-tionsLow noise operation reduces the sound generated by theunit compared to nominal operating conditions.Low noise operation can be set in mode 2. There are twomethods to activate low noise operation of the outdoor unitsystem.The first method is to enable an automatic low noise opera-tion during night time by field setting. The unit will operate atthe selected low noise level during the selected time frames.The second method is to enable low noise operation basedon an external input. For this operation an optional acces-sory is required.[1-2]= shows the status of power consumption limitation operation.• 1=unit is currently operating under power consumptionlimitation• 0=unit is currently not operating under power consump-tion limitationsPower consumption limitation reduces the power consump-tion of the unit compared to nominal operating conditions.Power consumption limitation can be set in mode 2. Thereare two methods to activate power consumption limitation ofthe outdoor unit system.The first method is to enable a forced power consumptionlimitation by field setting. The unit will always operate at theselected power consumption limitation.The second method is to enable power consumptionlimitation based on an external input. For this operation anoptional accessory is required.[1-5]= shows the current Te target parameter position.Refer to 15.3. Energy saving and optimum operation onpage 37 for more details about the contents of this value.[1-6]= shows the current Tc target parameter position.Refer to 15.3. Energy saving and optimum operation onpage 37 for more details about the contents of this value.[1-10]= shows the total number of connected indoor units.It can be convenient to check if the total number of indoorunits which are installed match the total number of indoorunits which are recognized by the system. In case there is amismatch, it is advised to check the communication wiringpath between outdoor and indoor units (F1/F2 communica-tion line).[1-13]= shows the total number of connected outdoor units.It can be convenient to check if the total number of outdoorunits which are installed matches the total number of out-door units which are recognized by the system. In case thereis a mismatch, it is advised to check the communicationwiring path between outdoor and outdoor units.[1-17]= shows the latest malfunction code.[1-18]= shows the 2nd last malfunction code.[1-19]= shows the 3rd last malfunction code.When the latest malfunction codes were reset by accidenton an indoor unit user interface, they can be checked againthrough this monitoring settings. For the content or reasonbehind the malfunction code see 15.5. Malfunction codelist on page 40, where most relevant malfunction codes areexplained. Detailed information about malfunction codes canbe consulted in the service manual of this unit.[1-40]= shows the current cooling comfort setting. See 15.3. Energysaving and optimum operation on page 37 for more detailsabout this setting.[1-41]= shows the current heating comfort setting. See 15.3. Energysaving and optimum operation on page 37 for more detailsabout this setting.
