Terminal Description
15 and 16
17 and 16 S1 Outdoor temperature
18 and 16 S2 Flow temperature sensor,
19 and 16 S3 Return temperature sensor ESM-11 / ESMC /
20 and 16 S4 Flow temperature sensor,
21 and 16 S5 Return temperature sensor,
22 and 16 S6 Upper tank temperature
* The system device bus / room panel / remote control is only active
when the outdoor temperature sensor is connected.
** Either room temperature sensor or room panel / remote control
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).
