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
s
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.
