On the master air/water heat exchanger
(00 = factory setting), set the number of slave units
present in the network:
01: Master with 1 slave air/water heat exchanger
02: Master with 2 slave air/water heat exchangers
03: Master with 3 slave air/water heat exchangers
04: Master with 4 slave air/water heat exchangers
05: Master with 5 slave air/water heat exchangers
06: Master with 6 slave air/water heat exchangers
07: Master with 7 slave air/water heat exchangers
08: Master with 8 slave air/water heat exchangers
09: Master with 9 slave air/water heat exchangers
Fig. 26: Master-slave connection (example)
For details of how to set the identifier,
see “6.2.5 Editable parameters”, page 18 or
“6.2.7 Programming overview of e-Comfort
controller”, page 20, parameter “Ad”.

(00 = factory setting), set its own address:
11: Slave air/water heat exchanger No. 1
12: Slave air/water heat exchanger No. 2
13: Slave air/water heat exchanger No. 3
14: Slave air/water heat exchanger No. 4
15: Slave air/water heat exchanger No. 5
16: Slave air/water heat exchanger No. 6
17: Slave air/water heat exchanger No. 7
18: Slave air/water heat exchanger No. 8
19: Slave air/water heat exchanger No. 9
