Use minor straight
screwdriver to dial.
In most scenarios, it is recommended to keep all
outdoor unit board dip switch positions in their
manufacturer default positions. There are some
specific scenarios when it makes sense to
change dip switch settings.
Dip Switch SW1
SW1-1 sets the Snow Sensor Control mode.
SW1-2 selects Tonnage of the condensing unit.
SW1-3 sets Air Conditioner or Heat Pump
SW1-4 is suggested to remain in the factory
default position (OFF). IoT command responses
such as remote field setting, troubleshooting,
software programming etc. only work when this
switch remains in the OFF position.
Must power off the unit for at least two (2) minute to activate your dial of switches.
