Setting method
To perform a group

the group with the
greatest number of
functions as the main
unit.
None of these ad-
dresses may overlap
any of the indoor unit
addresses.
It is not necessary to
set the 100s digit.
To set the address
to 200, set the rota-
ry switches to 00.
To set the address to
100, set the rotary
switches to 50.
If the address as-
signed to the hydro
unit overlaps any of
the addresses as-
signed to the outdoor
units, use a different,
unused address in the
specified setting
range.
