B 9 - Solar system with 2 storage tanks and zone valve
Sensor connection - max. 12V Mains voltage - 230V 50Hz
Low voltage - sensor connection
Terminal: connection for:
S1 (2×) sensor 1 collector
S2 (2×) sensor 2 storage tank 1
S3 (2×) sensor 3 storage tank 2
The polarity of the sensors is freely selectable.
Mains voltage - 230V 50Hz
Terminal: connection for:
L mains phase conductor L
N mains neutral conductor N
R1 pump L (speed)
N pump N
R2 zone valve L
N zone valve N
PE protective conductor (green-yellow)
Note: Actuating direction of zone valve:
R2 off = valve closed = flow direction B-AB = storage tank 1 charging (sensor S2)
R2 on = valve open = flow direction A-AB = storage tank 2 charging (sensor S3)
R1 output: for speed control of standard pumps, minimum load 20VA.
