The pump is wired directly to the power supply of control unit.
The power cord of the control unit, wired on factory, comes out from the frontal cover in
correspondence of the plumbing connections to the solar collectors and ends with a stretch of
about 10/20 cm. The connection to the electric cabinet must be made by the installer.
The connection of the sensor T1 to the control unit has already been done at the factory. The
prolongation of the sensor T1 (temperature sensor of the solar field) comes out from the frontal
cover in correspondence of the plumbing connections to solar collectors and ends with a power
terminal.
