Functional description of function dial-up:
DIP swicth 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 (DIP swicth 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.
DIP swicth 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 (wired controller). This setting is factory defaulted (DIP
swicth 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 from
the wired controller directly. The remote control mode refers to that the indoor unit is controlled from remote
controller. When the setting is remote control mode, its function dial-up must be set on S7.
DIP swicth 3 (M/S): The setting of master / slave indoor unit refers to the master / slave setting of indoor
run mode, mainly used to meet the needs of special people on priority (e.g. leader, patients, etc). The factory
default setting is that all indoor units are master (DIP swicth pulled to "ON" position).
When all the indoor units are set as slave, the outdoor unit will run according to the mode of slave indoor
indoor unit (except that the master indoor unit is stopped). In this case, the unit run according to the mode of
master indoor unit on priority.
When several indoor units are set as master, the mode of master indoor unit with a lower address code
will be taken as the master run mode of the unit. when the master indoor unit with the lowest address code is
changed from STOP state to RUN state, the mode of other master indoor units or slave indoor units shall be
several master indoor units, the address code of the unit shall be set from lower to higher according to priority
level.
DIP swicth 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 return 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 return air inlet and
setting of the temperature acquisition point at receiver head. The factory default setting is acquisition of return
air inlet temperature (DIP swicth pulled to "ON" position).
DIP swicth 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 (DIP
swicth pulled to "ON" position).
Cautions:
1)The above settings must be done under power shutdown state.
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 DIP swicth 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".
