7.2 PV contact

Contact AN10 can be used for Photovoltaic (PV) signal.
It's a dry contact which, when closed, makes
program switch from parameter R01 to parameter R14
for the hot water set point. This allows to set R14 higher
than R01, for storing more heat in the tank while the PV
system supplies electricity.
The same contact can be used for Smart Grid signals,
being sent from power companies when there is low
price supply of electricity. This enables the heat pump to
reduce even more the heating costs.
