B17 - Solar system + solid fuel boiler
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
S3 (2×) sensor 3 solid fuel boiler
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 boiler pump L
N boiler pump N
PE protective conductor (green-yellow)
R1 output: for speed control of standard pumps, minimum load 20VA
Caution
B18 - Solar system + zone valve + thermostat
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 lower
S3 (2×) sensor 3 storage tank upper
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
N pump N
R2 valve L
N valve N
PE protective conductor (green-yellow)
Note: Actuating direction of zone valve:
R2 off = valve closed = flow direction B-AB = backup heating
R2 on = valve open = flow direction A-AB = no backup heating
R1 output: for speed control of standard pumps, minimum load 20VA
