How to simultaneous operating
- Keep the following procedure when simultaneously operating two units or more cassette type, duct type, and
convertible type of indoor units via the free joint.
1. Turn on the power of the unit by the installed remote controller, a wire or a
wireless remote controller. When an installation professional installs it,
only one wire remote controller is installed except the location with only the
Convertible combination installed (using the wireless remote controller)
when completing the indoor unit setting (Cassette ceiling top/bottom, Duct
E.S.P. value).
2. After setting the desired operation mode and temperature and then starting
the unit to operate, wait for 2 or 3 seconds.
3. The remaining unites simultaneously starts with the same setting mode to
operate.
4. If you want to stop operating, the remaining units are operated to stop in 2
or 3 seconds by the installed remote controller. (However, the location with
only the Convertible combination is operated by the wireless remote con-
troller.)
5. For more information about how to operate the remote controller, refer to
