Remarks:
In case of cooling operation, the curves of "Expansion Valve
Opening" for indoor unit is not available due to the following
reasons.
a) The range of indoor unit valve opening for stability is wide
due to balancing control (*3) even if Td · SH is the same.
b) Indoor Units Expansion Valve Opening is slightly
changed depending on the total indoor unit quantity and
capacity to be connected.
c) Indoor Unit Expansion Valve Opening slightly changed
depending on the piping length.
