DIP SWITCH SETTINGS FOR MULTI SYSTEM INSTALLATIONS

if the indoor units of several MVA systems have to be managed, cer-
tain dip switches have to be set on the MASTER outdoor units of each
system (if one or more systems foresee several modules, these settings
must ONLY be performed on the Master module); The DIPs to be set
are as follow:
• SA2 = Dip to specify the address of the system in relation to the
MVACC accessory;
• SA8 = Dip to specify if the outdoor unit is Master or Slave;
The procedure to change the value of the dip switches on the outdoor
units is as follows:
WARNING:
To be able to set the DipSwitch it is possible to access
through the flap located on the bulkhead that pro-
tects the electronic board of the outdoor unit.
Each Master outdoor unit to be connected to the MVASZC accessory must have
a unique address from 0 to 15, where the system with address 0 will be considered
the Master system by the MVASZC accessory ; below is a table with the values to be
assigned to dip SA2 to specify the various addresses:

least two outdoor modules)

WARNING:
• In the positioning of the dipswitches, the "0" status is
represented with the Dip lever positioned up, towards
the wording "ON" as shown in the relative figure;
• The possible setting of the Dipswitches must be
done while the unit is NOT connected to the power
source;
• The system (in case of installations with several
modules) must have one MASTER while the remain-
ing modules must be set as slaves;
