(a) Cassette-type indoor units are set to “Enabled (3-minute delay)” regardless of digit 8 setting.
(b) For heat pump systems, the master indoor unit controls whether the system operates in heating or cooling. If the master indoor unit calls for heating
and slave indoor units calls for cooling, the master indoor unit (and any other slave indoor units that call for heating) will operate in heating mode. The
slave indoor units that call for cooling will do nothing.
(c) Digit 15 requires that an external contact interface module be connected. Refer to VRF-SVN54.
