Circuit Setting range Factory setting

I 0 ... 9, 15 15

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.
