Setting the Pipe Addresses Automatically (Auto pipe pairing operation)
You can use the Automatic pipe-address setting operation to automatically set the address of each MCU port that is
connected to an indoor unit .
If an MCU port is set incorrectly or a pipe between an MCU and an indoor unit is connected incorrectly, that indoor unit
is indicated .
Check items before running the Auto pipe pairing operation
1 . Ensure that the service valve of the outdoor unit is open .
2 . Ensure that the power cables and communication cables of the indoor and outdoor units are correctly connected .
3 . Turn on the indoor and outdoor units 6 hours before running the Automatic pipe-address setting operation to
warm up both units sufficiently .
4 . Before turning on the power, check whether the voltages and phases are correct by using a voltmeter and a phase
tester .
- Check for the R, S, T, and N terminals: ensure that 380-415V is read between lines (R-S, S-T, T-R) and 200-240V
(R-N, S-N, T-N) between phases .
5 . After the power is turn on, set the devices (indoor unit, MCU, and others) that are connected to the outdoor unit,
and set the options .
Note that, before the MCU port addresses are set, MCU port setting errors (E216, 217, 218) may occur . You can run
the Automatic pipe-address setting operation regardless of MCU port setting errors .
6 . If the OAP(Outdoor Air Processing) Duct or Hydro unit is connected, set the pipe addresses manually referring to
[Setting the Pipe Addresses Manually] .
7 . Check the operating temperature for the Automatic pipe-address setting operation:
If this operation is run at a temperature out of the operating temperature range, the addresses set automatically
may be incorrect . Set the pipe addresses manually by referring to Setting the Pipe Addresses Manually .
8 . Auto pipe-pairing operation does not work within 3 minutes after power on and reset due to communication
check .
