The outdoor fan high static pressure support and priority operation mode setting (cooling / heating / number of units
/ or priority indoor unit) functions are made available by setting relevant switches provided on the interface P.C.
board of the outdoor unit.
Purpose/characteristics
This function is used when connecting a duct to the discharge port of an outdoor unit (as part of, for example, unit
installation on the floor by floor installation.)
Setup
Turn ON the DIP switch [SW10, Bit 2] provided on the interface P.C. board of the outdoor unit.
This function must be enabled with every discharge duct connected outdoor unit for both of the header and follower
units.
Specification
Increase the speed of the propeller fan units on the outdoor fan to allow the installation of a duct with a maximum
external static pressure not greater than specified in the table below. If a discharge duct with a resistance greater
than 15 Pa (1.5 mmAq) is to be used, enable this function. The maximum external static pressures of base units
are shown below (Table 1). In the case of combined use of multiple outdoor units, set all the units to the same
maximum external static pressure as the one with the lowest maximum external static pressure (see table2).
