The setting of 'Slave addr.' is related to the setting 'ECA
address' in the ECL controller.
In the ECL controller it is selected from which ECA 30 / 31
unit the room temperature signal is received.
A:
The ECA 30 / 31 has the address A.
B:
The ECA 30 / 31 has the address B.
For installation of an application in an ECL Comfort 210 / 310 controller
the 'Slave addr.' must be A.
If two ECA 30 / 31 are connected in the same ECL 485 bus system, the
'Slave addr.' must be "A" in the one ECA 30 / 31 unit and "B" in the other.

Master controller.
An ECA 30 / 31 can in an ECL 485 bus system (master – slave) be set to
communicate, one by one, with all addressed ECL controllers.
Example:
Connection addr. = 15:
The ECA 30 / 31 communicates with the
ECL master controller.
Connection addr. = 2:
The ECA 30 / 31 communicates with the
ECL controller with address 2.
There must be a master controller present in order to broadcast time
and date information.
An ECL Comfort controller 210 / 310, type B (without display and dial)
cannot be assigned to the address 0 (zero).
