(4) Determine Fan Airflow setting during Indoor Thermo OFF conditions:
a) These settings are done within Indoor DIPSW1-7 and DIPSW1-8, see chart below for options.
b) Recommended SW1-7 OFF and SW1-8 ON will determine airflow based on "Setting on the remote controller".

(5) Setting Outdoor unit and Auxiliary heat switch over temperatures.
When the DIPSW 4-4 is set to "ON", the outdoor unit and the contact output operates as shown below.
a) Outdoor default setting and operations are shown below:

a) With no Primary heating output the Indoor fan normally goes off to prevent cold drafts during the defrost cycles.
b) With Primary heating control the auxiliary heat will be on during defrost mode, thus cold drafts will not be present.
(Ducted units only)
c) For models PEFY and PDFY (Ducted) recommended to use "Black" (20K) connector.
d) For models PLFY, PCFY, PKFY and PFFY (Ductless) recommended "None", no connector required.
e) To set the fan airflow rate to be used during defrost operation, insert the resistance that is packed within the optional
adaptor cable kit (PAC-YU24HT-F) into the CN22 sensor input.
You can choose at what speed the indoor fan operates during defrost cycles bases on chart below.
