The setting is relevant when more controllers are working in the
same ECL Comfort system (connected via the system device bus
(ECL Comfort BUS)).
0:
The slave receives information about the
outdoor temperature (S1), system time, and
signal for DHW demand in the master.
1 ... 9:
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.
15:
The controller is master. The master sends
information about the outdoor temperature
(S1), system time, and the DHW demand
signal.
The master receives the desired flow
temperature information from the slaves
with addresses 1 ... 9.
The bus is active and connected ECAs are
powered.
The ECL Comfort controllers can be connected via the bus to
perform a larger system. The controller, which is physically
connected with the outdoor temperature sensor, is the
master of the entire system and automatically gets the
address 15.
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, system
time, and signal for DHW demand in the master.
