Technical information
11.3.6 EVU/SG wiring diagram for the indoor unit with an
integrated electric booster heater

11.3.7 Photovoltaic

Since there are only two external inputs for the energy supplier and PV,
these cannot be used at the same time.
PV connection to external input 1 or 4.
The heat pump is able to process a control signal of a PV system.

If the PV system has sufficient current for operating the heat pump, it can
communicate this information to the heat pump in the form of a start
command via a control cable. The control cable must be connected to
one of the available external connections. The selected external
connection must be configured in the control unit for the PV function.
The heating system must have a buffer cylinder and only heating circuits
with a mixer in order for a start command to be effective. A start
command causes the buffer cylinder to be charged up to the maximum
temperature achievable by the heat pump. However, it can only be
charged when the temperature in the buffer cylinder is below the
maximum temperature. Otherwise, the heat pump remains off.
