This settting is relevant if more controllers are working in the same ECL
Comfort system (connected via the ECL 485 communication bus) and / or
Remote Control Units (ECA 30 / 31) are connected.

0:

The controller works as slave.
The slave receives information about the outdoor
temperature (S1), system time, and signal for DHW
demand in the master.

1 ... 9:

The controller works as slave.
The slave receives information about the outdoor
temperature (S1), system time, and signal for DHW
demand in the master. The slave sends information
about the desired flow temperature to the master.

10 ... 14:

Reserved.

15:

The ECL 485 communication bus is active.
The controller is master. The master sends information
about the outdoor temperature (S1) and system time.
Connected Remote Control Units (ECA 30 / 31) are
powered.

The ECL Comfort controllers can be connected via the ECL 485
communication bus to perform a larger system (the ECL 485
communication bus can connect to max. 16 devices).

Each slave must be configured with its own address (1 ... 9).

However, more slaves can have the address 0 if they only have to
receive information about outdoor temperature and system time
(listeners).

The total cable length of max. 200 m (all devices incl. the internal ECL
485 communication bus) should not be exceeded.
Cable lengths of more than 200 m may cause noise sensibility (EMC).
