6. Electrical connection
Electrical connection includes sensor connection, mains supply and controlled
pump according to Figure 2 . The sensors are Pt1000 type – non-polar.
If necessary, the connecting cables of the
sensors can be extended, taking into account the
total resistance of the two wires - sensitivity of the
indication
1°С/4Ω
. A recommended length that
does not affect the measurement is up to 100m .
Terminals 8, 9 are input for the sensor from the
solar panels.
Terminals 10, 11 are input for the sensor from the
boiler.
A Pt1000 sensor is connected to them.
Terminals 1, 2 and 3 are supplied with neutral,
phase and protective earth respectively from the
mains.
The pump is connected to terminals 4, 5 and 6, on which protective earth, neutral
and phase come out, respectively. A phase (L2) is output on terminal 7, while it is
not output on terminal 6 (L1).
Attention:
In order to remove the static electricity that accumulates in the solar
panels, it is mandatory that they as well as their metal structure to be
grounded. Otherwise, there is a risk of damaging the sensors as well as the
controller.
