B - ELECTRIC WIRING
B 1 - Solar system with storage tank
Example: solar system with storage tank and el. heating rod with integrated 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
S3 (2×) sensor 3 (e.g. for heat balance)
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 pump L (no speed control)
R1 pump N
PE protective conductor (green-yellow)
Note: Sensor 3 can be used to measure heat quan-
tity supplied by the solar system.
R1 output: for speed control of standard pumps, minimum load 20VA.
Caution
B 2 - Solar system with thermostat for storage tank heating or cooling
Example: solar system with storage tank heated with a gas boiler or el. heating rod, controller regulated.
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 thermostat function L
N thermostat function N
PE protective conductor (green-yellow)
R1 output: for speed control of standard solar pumps, minimum load 20VA.
