• The standard opening is on the straight line, which connects an each standard point in the section where divided into seven
according to the operation frequency of compressor as shown in the figure below.
(LEV opening is controlled in proportion to the operation frequency.)
NOTE
: Opening is adjusted at the standard opening according to the indoor unit conditions.
However, inclination of standard opening in each point of opening does not change with the original curve.
• Add opening provided in Difference in Capacity in the table below to the standard opening from 1 to 8 (
MXZ-2B
)/ 1 to 15 or
above (
MXZ-3B/4B/5B/3C/4C/5C/6C
), when capacity of the indoor unit is excluding code 1.
• Add opening provided in Difference in Operation number in the table below to determined LEV opening for each indoor unit,
when 2, 3, 4, 5 or 6 indoor units are operated at the same time.
NOTE:
Even when the adjusted standard opening exceeds the driving range from 59 to 500 pulse, actual driving output opening
is in a range from 59 to 500 pulse.
