7. APPLIED CONTROL AND FUNCTION
7-1. Applied Control for Outdoor Unit
The outdoor fan high static pressure support functions are made available by setting relevant switches
provided on the interface P.C. board of the outdoor unit.
7-2. Outdoor Fan High Static Pressure Shift
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 0.06 InWG (15 Pa) 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).
