For the following conditions, a micro computer controls the air flow direction
which may be different from the display.
Cooling
▪
When the room temperature is lower
than the set temperature.
▪
When operating continuously at horizontal air flow direction.
▪
When continuous operation with downward air flow is performed at the time of
cooling with a ceiling-suspended or a wall-mounted unit, the micro computer
may control the flow direction, and then the user interface indication will also
change.
The air flow direction can be adjusted in one of the following ways:
▪
The air flow flap itself adjusts its position.
▪
The air flow direction can be fixed by the user.
▪
Automatic
and desired position .

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.
