8. Photovoltaic Function Connection
This appliance provides the function to use the energy from photovoltaic system. Users
can
choose
to
use
this
function
if
a
photovoltaic system
is installed
.
The photovoltaic function is enable when a contact signal is established between the two wires of
t
he photovoltaic inverter connecting cable. T
his
function can exploit any overproduction of
electricity and it increases the water temperature until it reaches the heat pump default
temperature 65
℃.
