2.6 Dip switch configuration
Set the indoor fan speed through the eight dip switches of the indoor main control
board. The higher level, the higher speed of the indoor unit fan. Operation Instruction is
below:
Dip switch settings must be completed before power on the unit.
After the unit is shut down or stopped at the temperature point, the indoor unit will
delay for a few minutes and then shut down. The refrigeration can realize the drying
function, relieve the mold of the air duct, and the heating can blow the waste heat and
relieve the heat accumulation in the air duct.
During installation and debugging, pay attention to check whether the temperature
controller has set the fan delay and shutdown time. If the temperature controller has
been set, the actual delay and shutdown time of the fan is equal to the temperature
controller setting time plus the fan delay time of the indoor unit.
