Solar Control/Electric Installation (16)
Note:
• The electric installation must be performed by
an authorised professional!
• Fuses, wiring, and grounding must be installed in
compliance with local regulations.
• The solar control must be protected against
overcurrent damage.
• Disconnect the system from the mains before
opening the casing of the solar control!
The pump cable and the power cord are already con-
nected to the solar control.
Remove the screw in the cover of the solar control
(pos. 16) to access the sensor terminal.
Connect the sensors according to the installation
guide of the solar control.
See the installation guide of the solar control for a
description of the functions and instructions for use.
