Dial-up Switch
1(S / R)
2(L / I)
3(M / S) Setting of master / slave indoor unit
4(I / O)
5(L / H) Setting of high / low static pressure fan
Functional description of function dial-up:
Dial-up switch 1 (S/R):
Setting of memory mode, including the standby mode and restoration mode. The standby mode refers
to that the previous parameters will be kept but the unit will not run automatically after the power supply
is resumed. This setting is factory defaulted (dial-up switch pulled to "ON" position). For example, if the
parameters of an indoor unit set before power shutdown are High Fan and 24 , the unit will be under standby
state after the power supply is resumed and after the unit is manually started, the parameters will remain as
High Fan and 24 . The restoration mode refers to that not only the previous parameters will be kept, but also
that the unit can start automatically after the power supply is resumed. But if the unit is under STOP state
before power shutdown, it will be also under STOP state after the power supply is resumed.
Dial-up switch 2 (L/I):
Setting of control mode, including wired control and remote control. The wired control mode refers to that
the indoor unit is controlled from wired controller (hand controller). This setting is factory defaulted (dial-up
switch pulled to "ON" position). When the setting is wired control mode, the function dial-up on S7 for "setting
of memory mode" and "setting of master / slave indoor unit" will be disabled. These two settings can be done
