When all the indoor units are set as slave, the outdoor unit will run according to
the mode of slave indoor unit that is firstly started. If the mode of slave indoor
unit started later has in conflict against the mode started earlier, the system will
display mode conflict error, so that the indoor unit started later cannot work. In
this case, the run mode of the unit is decided by the slave indoor unit that is
firstly started.
When only one indoor unit is set as master, no matter if the master indoor unit is
firstly started or not, the slave indoor unit will give out mode conflict error as long
as its mode is in conflict against the mode of master 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 kept identical to its mode; otherwise the system will give out mode
conflict error. Therefore, when there are 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.
2)The DIP swicth 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 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”.
5)After dialing up, please mark the address code of the unit(
