INSTALLATION AND
INITIAL OPERATION
For installation and connection always follow the inclosed instructions.
Parameter P2.1 is used to set the address for the room unit manually:
P2.1=0 - room unit address is set automatically,
P2.1=1 - Room unit address is 1,
P2.1=2 - Room unit address is 2.
During initial operation, room unit address is set automati-
cally. If one room unit is connected, it acquires address 1. If
an additional room unit is connected, it acquires address 2.
If two room units are connected simultaneously, address has
to be confirmed or set on one of them, and the other room
unit automatically acquires the remaining address. By factory
settings, room unit 1 affects the first, and room unit 2 affects
the second heating circuit.
