6.3 - PHOTOVOLTAIC SYSTEM

The internal unit UI is equipped with two inputs for connection to a photovoltaic system.
Parameter "ADDR341"
0 = disabled
1 = enabled
When one or both of the FTV inputs are closed, it is possible to automatically force the accumulation of
energy by requesting the internal unit to heat more (if in heating mode or in domestic water production) or
to cool more (if in cooling mode)
Parameter "ADDR347" cooling water delta
Parameter "ADDR348" heating water delta
Parameter "ADDR349" domestic water delta

6.4 - CHECK OF THE CIRCULATION PUMPS

During installation, the operation of the circulation pump can be forced for 15 minutes from the window on
the control display "Pumps"; in that way, air bleeding is eased in the final filling phase of water in the system.
The circulation pump can work in different modes depending on the needs of the system:
- Continuous operation of the pump (parameter ADDR221=OFF=0)
- Switching off upon reaching the desired temperature (parameter ADDR221=ON=1) and sampling every
ADDR237 minutes for one minute (parameter ADDR237=10 minutes, the pump will activate for one minute
every ten minutes).
When the system is in stand-by or with fulfilled set point, the anti block function of the system and DHW circuit
pumps is present; setting the parameter ADDR221=ON=1, the pump is activated every ADDR222 hours for
a time equal to ADDR223 seconds).
The parameters above can be set in the window Service.

6.5 - AUXILIARY EXTERNAL HEAT SOURCE MANAGEMENT

In heating or domestic water production mode, set the parameter ADDR226=ON=1 and, if external ambient
temperature is lower than ADDR227 degrees centigrade, the control will provide for the replacement of the
heat pump with the activation of an output for enabling of an external heat source.

7 - USE

7.1 - PRODUCTION OF DOMESTIC HOT WATER

During the production of domestic hot water with the main heat pump, the system produces as much
power as possible to quickly meet the request for domestic hot water.
The request for domestic water can occur in the follow manners:
• Through DHW/L contact and setting parameter ADDR228=1; in this case, set the external thermostat at
a temperature lower than 70°C.
• Through a temperature sensor inserted in the domestic hot water reservoir setting parameter A DDR228=2;
in this case, the set point is determined by parameter ADDR210.
With parameter ADDR228=0, the production of domestic hot water is disabled.
With parameter ADDR238 it is possible to change the hysteresis cycle of the domestic water temperature check.
The temperature sensor T3 supplied in the internal module must always be inserted in and connected
to the domestic hot water reservoir.
