Electrical connection
For enabled yield calculation with actually measured fl ow rate
(possible with confi gurations 1, 3, 4, 5, 6), the fl ow rate generator
is connected to input E2. This is part of the heat meter set
(accessories).
Input E3 is assigned differently, subject to the selected system
confi guration:
Confi guration 3, 4: Cylinder sensor solar cylinder 2 (NTC)
Confi guration 5, 6, 7, 8: Collector sensor collector array 2
(PT1000)
Confi guration 2: Buffer sensor (NTC)
Confi guration 9, 10, 11: Bypass sensor (NTC)
The input is not assigned with confi guration 1.
When using the solar module SM2 as part of a Wolf control system,
the individual components are linked together via eBUS.
H005VV 3x1.0 mm²
H05VV 3x0.75mm² Solar circuit pump, three-way diverter
H05VV 2x0.5mm²
H05VV 2x0.5mm²
H05VV 2x0.75mm² Sensor leads up to 50 m
During service work, isolate the entire system from the power
supply, otherwise there will be a risk of electrocution.
