Networking System
Master-Slave Network
The control PCB can be set either as a master unit or slave unit.
Mater Unit Function
a) The master unit sends data regarding its setting to the slave unit.
b) The master unit settings are unit ON/OFF, Mode, Fan Speed, Timer, Clock, Set Temperature, Louver Function, and Sleep
Function for handset operation.
c)
The master unit settings are unit ON/OFF, Mode, Fan Speed, Timer, Clock, Set Temperature, Louver Function, and Sleep
Function for wall pad operation.
Slave Unit Function
a) The slave unit receives data regarding its settings from the master unit.
b) The slave unit is allowed to change to a locally desired setting by local controller as long as there are no subsequent
changes to the settings of the master unit.
c)
The slave units can be set individually for timer ON/OFF function by handset or wall pad. The handset cannot override
the wall pad timer and clock setting.
Master Unit Control Settings
The control PCB can receive data from both wireless Infrared handset and wired wall pad.
Using Remote Control Handset to Set Master Control Unit:
1. Connect all the units PCBs according to the wire color and type of connector.
2. Select the master unit by setting DIPA-S1 SW6 to ON (=1) in the PCB.
3. Ensure the DIPA-S1 SW6 is set to OFF (=0) in the PCB on each slave unit.
4. Switch on the units by connecting the main power supply.
5. Using the handset, set the operation parameters for the master unit which will automatically send the settings to the
slave unit.
6. Master unit will beep twice confirming receipt of commands while the slave unit will beep once.
Using Wall pad to Set Master Control Unit:
1. Connect all the units PCBs according to the wire color and type of connector.
2. Select the master unit by setting DIPA-S1 SW6 to ON (=1) in the PCB.
3. Ensure the DIPA-S1 SW6 is set to OFF (=0) in the PCB on each slave unit.
4. Provide each slave unit with an addressable code by configuring SW1 – SW5 of DIPA-S1 according to the DIP switch
setting table.
5. Switch on the units by connecting the main power supply.
6. Using the wall pad set the operation parameters for the master unit which will send the setting to the slave units by
Global-control communication or Addressable communication methods.
7. Master unit will beep twice confirming receipt of commands while the slave unit will beep once.
