Dial-up switch 4 (I/O):
Setting of ambient temperature acquisition point. This setting is mainly used when the temperature of air conditioner
area differs largely from the air inlet temperature of the unit. Meanwhile, this setting is only valid when the receiver is
connected, including the setting of temperature acquisition point at air inlet and setting of the temperature acquisition point
at receiver head. The factory default setting is acquisition of air inlet temperature (dial-up switch pulled to “ON” position).
Dial-up switch 5 (L/H): Setting of high / low static pressure fan. This setting includes the setting of high static
pressure fan and low static pressure fan, adjusted as needed for the project. The factory default setting is low static pressure
fan (dial-up switch pulled to “ON” position).
Cautions:
1) The above settings must be done under power shutdown state.
2) The dial-up switch of function code is classified into 3-bit code, 4-bit code and 5-bit code. The 4-bit code or 5-bit
code is used for duct-type unit only (including multi duct-type unit and 1-to-1 duct-type unit).
3) When the “setting of control mode” is “L”, the function dial-up for “setting of memory mode" and “setting of
master / slave indoor unit” will be disabled. When the “setting of control mode” is “I”, this function dial-up setting is
enabled.
4) The dial-up switch shall be put to position correctly, and shall not be put to middle position. Dialing of the switch
to “ON” position indicates “0” and the dialing to opposite direction indicates “1”.
5) After dialing up, please mark the address code of the unit(√).
