12.  Checking of device and installation conditions

Be sure to check the followings.

For those doing electrical work

Make sure there is no faulty transmission wiring or loosening of a 
nut.

See 9.4. Transmission wiring connection procedure on page 20.

Make sure there is no faulty power wiring or loosening of a nut.

See 9.5. Power wiring connection procedure on page 21.

Has the insulation of the main power circuit deteriorated?
Measure the insulation and check the insulation is above regular 
value in accordance with relevant local and national regulations.

For those doing pipe work

Make sure piping size is correct.

See 7.2. Selection of piping material on page 9 and 7.4. Selection of 
refrigerant branch kits on page 11.

Make sure insulation work is done.

See 11. Pipe insulation.

Make sure there is no faulty refrigerant piping.

See 8. Precautions on refrigerant piping on page 14.

13. 

Making field settings

To continue the configuration of the outdoor units, it is required to give 

some input to the printed circuit board of the unit. This chapter will 
describe how manual input is possible by operating the push buttons/
DIP switches on the printed circuit board and reading the feedback 
from the 7 segment displays.
For VRV Aurora series it is alternatively possible to make several 

commissioning field settings through a personal computer interface 
(for this, option 999482P3 is required). The installer can prepare the 
configuration (off-site) on PC and afterwards upload the configuration 

to the system. How to connect the cable is described in  

13.3. Connecting the PC configurator to the outdoor unit on page 26.

The contents of the actual settings is discussed and explained in 15.2. 
Monitoring function and field settings on page 31.
For a complete list of indoor and outdoor unit field settings, refer to the 

online service manual of this outdoor unit.

13.1.  Accessing the push buttons on the printed circuit 

board

It is not required to open the complete control box to access the 

push buttons on the printed circuit board and read out the 7 segment 

display (s).

To access you can remove the service window cover (see figure). Now 
you can open the inspection door of the control box cover (see figure). 
You can see 3 push buttons and 3 seven-segment displays and DIP 

switches.

13.2.  Operating the push buttons and DIP switches on 

the printed circuit board

13.2.1.  Operating the push buttons

By operating the push buttons it is possible to:

• 

Perform special actions (automatic refrigerant charging, test run, etc).

• 

Perform field settings (demand operation, low noise, etc).

Below procedure explains how to operate the push buttons to reach 

the required mode in the menu, select the correct setting and modify 

the value of the setting. This procedure can be used any time special 

settings and regular field setting are discussed in this manual (see 
15.2. Monitoring function and field settings on page 31).

Setting definition: [A-B]=C; A=mode; B=setting; C=setting value. A, B 
and C are numerical values for field settings. Parameter C has to be 
defined. It can be a chosen from a set (0, 1, 2, 3, 4, 5, …) or regarded 
as an ON/OFF (1 or 0) depending on the contents. This is informed 
when the field setting is explained (see 15.2. Monitoring function and 
field settings on page 31).

 INFORMATION

During special operation (e.g., automatic refrigerant charging, test 
run, etc.) or when an malfunction happened, information will contain 

letters and numerical values.

Functions of the push button switches which are located on the 
main printed circuit board (A1P)

Turn on the power supply of the outdoor unit and all indoor units. 

When the communication between indoor units and outdoor unit (s) is 
established and normal, the segment indication state will be as follows 
(default situation when shipped from factory):
