EVU-SG Digital inputs for photovoltaic input and smart grid from mains
electricity
If the digital inputs for photovoltaic input and smart grid from mains electricity are
enabled by parameter 15.2 (see “9.1.1 Access to Service menu (For Serviceman)"
on page 50) and are active. They take priority over the user interface settings.
Digital inputs not enabled (default)
Set par. 15.2 = 0
Digital inputs enabled
Set par. 15.2 = 1

Photovoltaic operation
The DHW heater setpoint is set to 70°C to accumulate the electrical energy pro-
duced by the photovoltaic panels.
To meet this DHW request tat 70°C, the heat pump and DHW (TBH) electrical
water heater are used.
If the heat pump is working for the system, continue to do so and only the DHW
electric boiler heater (TBH) is used.to meet the DHW request. If the heat pump is
not working for the system, it is activated together with the electric DHW heater
(TBH) to meet the DHW request.
•
Normal operation
In this case, the system works normally according to the set parameters
•
Smart grid operation
This operation is usually dependent of a smart grid request by the mains electricity
which basically informs the system that the deliverable electric power is decreas-
ing (for example, in the case of electricity production systems through wind or
photovoltaic farms).
The heat pump is not longer available to heat the DHW heater and can work for
the system in cooling or heating mode for a specific time (set via a parameter),
so is disabled.
NOTE
If you only want to use photovoltaic input, jumper SG
If you only want to use smart grid input, jumper EVU

Additional temperature probes
To control the additional system temperature probes, additional temperature
probes may be necessary (available as an accessory).
The probes are connected to the heat pump hydronic board (see “7.7.5 Hydronic
board" on page 34).
Refer to the instructions supplied with the accessory for the installation.
For the setting parameters, see “9.1.1 Access to Service menu (For Serviceman)"
on page 50.
