Installing transmitter and sub PCB for central control
Accessories (Transmitter : MIM-B13B)
1.
Turn the power off and take off the cover of the outdoor units.
2.
Fix the case with bolts to the side of the control box referring to
the figure on the right side.
In case of FJM outdoor unit, there is not enough space to fix all
parts of transmitter. So you may use transmitter main PCB.
3.
Attach the transmitter main PCB to the case, then connect F1/
F2 lines, R1/R2 lines which are upper controller communication
cables and DC 12V power cables to the interface module referring
to the figure on this page. (Upper controller power should be off.)
4.
You must check the position of dip switch on the transmitter's
main PCB and the main PCB of AJ***JNLD** indoor units. For
AJ***JNND**/AJ***JNAD** indoor units, refer to page 26~28.
5.
Assemble a cover of the outdoor unit and turn the power on.
6.
Check the communication status.
7.
If you install a transmitter to the outdoor unit, every indoor
unit which is connected to the outdoor unit can be controlled
simultaneously.
8.
Each outdoor unit connected to the same centralized controller
has its own transmitter.
9.
When using the centralized controller, refer to page 26~28 for
indoor unit setting.
