On-Site Configuration; Address Settings - mundoclima MVD DC2 Manual De Instalación Y Usuario

 For the specific connection method, refer to the instructions in the
corresponding wired controller manual to carry out the wiring and
connections.
 The X1, X2, D1, D2 ports on the sides of the main control board
and the unidirectional communication port (display board side) are
for different types of wired controllers (see Figure 6.10).
 Use the connecting wires (accessory 7) to connect the D1, D2 ports.

6.5 Handling the Electrical Wiring Connection Points
 Once the wiring and connections are done, use tie straps to
secure the wiring properly so that the connection joint cannot be
pulled apart by external force. The connection wiring must be
straight out so that the cover of the electrical box is level and can
be closed tightly.
 Use professional insulation and sealing materials to seal and
protect the perforated wires. Poor sealing may lead to
condensation, and entry of small animals and insects that may
cause short circuits in parts of the electrical system, causing the
system to fail.

7. On-site Configuration

7.1 Capacity Settings
Set up the PCB board DIP switch on the indoor electric control box to
cater to different uses. Once the settings are done, make sure you
cut off the main power switch again, and then switch the power on. If
the power is not cut off and switched on again, the settings will not be
executed.

Caution
• The capacity DIP switches have been configured before
delivery. Only a professional maintenance personnel should
change these settings.

7.2 Address Settings

When this indoor unit is connected to the outdoor unit, the outdoor unit
will automatically allocate the address to the indoor unit. Alternatively,
you may use the controller to manually set the address.
• The addresses of any two indoor units in the same system cannot
be the same.
• The network address and the indoor unit address are the same,
and does not have to be configured separately.
• Once the address settings are completed, mark the address of
each indoor unit to facilitate after-sales maintenance.
• The centralized control of the indoor unit is completed on the
outdoor unit. For details, refer to the manual on the outdoor unit.
Caution
• Once the centralized control function for the indoor unit has been
completed on the outdoor unit, the DIP switch on main control
panel of the outdoor unit must be set to auto addressing;
otherwise, the indoor unit in the system are not controlled by the
centralized controller.
• The system can connect up to 64 indoor units (address 0~63) at
the same time. Each indoor unit can only have one address DIP
switch in the system. The addresses of any two indoor units in
the same system cannot be the same. Units that have the same
address may malfunction.
