If the outdoor is not connected to the central control monitoring software (Smart Commander) or
the Central Wired Controller (MC303), there is no need to set the address. If the outdoor is
connected with these accessories, then the same rules on the indoor setting is applied here
also. The rules are as follow:
a) Each outdoor number must be unique. The outdoor address cannot duplicate.
b) The first outdoor address must be 0. Do not start the first outdoor with address 1.
c) While setting the outdoor address, the outdoor address number cannot skip. For
example, if there are only 4 outdoors in a system, the outdoor address needs to be 0, 1,
2 and 3.
d) It is advisable that the outdoor address follow the sequence of the communication
wiring. For example, for a 4 outdoors in the system, the first outdoor after the gateway
should have address 0, the next outdoor address should be 1 and the last outdoor of the
communication wiring should be 3.
