For VRV IV heat pump system it is alternatively possible to make several
commissioning field settings through a personal computer interface (for this,
option EKPCCAB* is required). The installer can prepare the configuration (off-site)
on PC and afterwards upload the configuration to the system.

Mode 1 can be used to monitor the current situation of
the outdoor unit. Some field setting contents can be
monitored as well.
Mode 2 is used to change the field settings of the
system. Consulting the current field setting value and
changing the current field setting value is possible.
In general, normal operation can be resumed without
special intervention after changing field settings.
Some field settings are used for special operation (e.g., 1
time operation, recovery/vacuuming setting, manual
adding refrigerant setting, etc.). In such a case, it is
required to abort the special operation before normal
operation can restart. It will be indicated in below
explanations.

Questions and answers
Hi, kindly assist me with resolving the problem of the VRV IV series. It pops up from the remote control, and after checking the master and the slaves, both cannot identify their ID number. though the last error was e2. Someone messed up with the wiring, perhaps the communication cable. If we can see what cable goes to the first unit from the master, we have 16 units attached.
The troubleshooting steps for a Daikin VRV IV series system with an E2 error and communication issues between the master and slave units are:
1. Check Q1/Q2 Wiring: Inspect the wiring connections between the master and slave units at the Q1/Q2 terminals. Faulty or incorrect wiring can cause communication failures.
2. Verify Indoor-Outdoor Wiring: Ensure that the wiring between the indoor and outdoor units is correctly connected at the Q1/Q2 and F1/F2 terminals. Incorrect connections can lead to system malfunctions.
3. Check System Test Run: If the system test run was not executed or ended abnormally, perform the test run again to identify potential issues.
4. Confirm Indoor Unit Configuration: Ensure that the number of indoor units connected to the F1/F2 line does not exceed the system's capacity. Too many units can cause communication failures.
5. Inspect System Compatibility: Verify that the indoor units connected are compatible with the system (e.g., R410A, R407C, Hydrobox). Mixing incompatible units may cause communication issues.
6. Examine Outdoor Unit Wiring: Ensure that the interconnecting wiring between outdoor units in the same piping system is connected to the Q1/Q2 (Out Multi) terminals. Incorrect wiring to the F1/F2 terminals can cause system malfunctions.
Following these steps should help diagnose and resolve communication issues in the VRV IV system.
