B 5 - Solar system with thermally stratified storage tank
Example: Heat gained from the solar system is stored either to the upper or to the lower tank part, depending
on the temperature achievable from the solar system.
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 (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 AB-B = flow to storage tank lower (sensor 2)
R2 on = valve open = flow direction AB-A = flow to storage tank upper (sensor 3)
R1 output: for speed control of standard pumps, minimum load 20VA.
B 6 - Solar system with heat exchanger
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 before heat exchanger
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, secondary L
N pump, secondary N
R2 pump, primary L
N pump, primary N
PE protective conductor (green-yellow)
R1 output: for speed control of standard pumps, minimum load 20VA.
