The solar cell captures the intensity of the sun and communicates this
to the solar control unit. The bypass pump will be switched ON if the
insolation exceeds the set switching threshold.
With connecting cable, 2.3 m long.
On-site extension of the connecting lead:
2-core lead, length max. 35 m with a cross-section of 1.5 mm
