temperature sensors
Connecting the temperature sensors and the bus
Terminal Description
15 and 16
17 and 16 S1 Supply temperature sensor
18 and 16 S2
19 and 16 S3 DHW temperature sensor
20 and 16 S4 Return temperature sensor
21 and 16 S5
22 and 16 S6
* The system device bus is only active when the address 15 (line 199)
is chosen.
** If only one DHW temperature sensor is used, it must be connected to
terminal 22 as S6.
Establish the jumper from 16 to common terminal.
Wire cross section for sensor connections:
Total cable length: Max. 125 m (all sensors incl. system device
Cable lengths of more than 125 m may cause noise sensibility
(EMC).
