Enable the low noise function and/or power consumption limitation via external
control adaptor (DTA104A61/62).
If the system needs to be running under low noise operation or under power
consumption limitation conditions when an external signal is sent to the unit, this
setting should be changed. This setting will only be effective when the optional
external control adaptor (DTA104A61/62) is installed.

Refrigerant recovery/vacuuming mode.
In order to achieve a free pathway to reclaim refrigerant out of the system or to
remove residual substances or to vacuum the system it is necessary to apply a
setting which will open required valves in the refrigerant circuit so the reclaim of
refrigerant or vacuuming process can be done properly.

To stop the manual additional refrigerant charge
operation (when the required additional refrigerant
amount is charged), push BS3. If this function was not
aborted by pushing BS3, the unit will stop its operation
after 30 minutes. If 30 minutes was not sufficient to add
the needed refrigerant amount, the function can be
reactivated by changing the field setting again.

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.
