3.10 FIRST IGNITION PARAMETER SETTING

During the first activation of the appliance, it is necessary to customise the following parameters, which concern the generator opera-
tion, the type of outdoor unit and the type of system connected to the appliance.
Heat pump power
Set parameter A11 according to the type of outdoor unit connected.
Circulator speed
Set parameter A05 to define the operating mode of the pump.
Set parameters A03 and A04 to define the maximum and minimum speed of the pump.
It is necessary to adjust the pump speed according to the appliance power, to improve the operating efficiency of the machine.
It is suggested to check the values as indicated in the following table:
Number of zones
Set parameter A13 according to the number of zones in the system that are directly controlled by the machine.

3.11 PUMP ANTI-BLOCK FUNCTION

The indoor unit has a function that starts the pump at least once every 24 hours for the duration of 30 seconds in order to reduce the risk of
the pump becoming blocked due to prolonged inactivity.

3.12 THREE-WAY ANTI-BLOCK SYSTEM

The indoor unit has a function that activates the motorised three-way unit 24 hours after the last time it operated by running a complete
cycle in order to reduce the risk of the three-way blocking due to prolonged inactivity.

3.13 RADIATORS ANTIFREEZE FUNCTION

If the system return water is below 8°C, the indoor unit pump starts up until reaching 10°C.

3.14 PHOTOVOLTAIC FUNCTION

If the photovoltaic contact (contact "S 39" Fig. 8) is closed, any DHW (Domestic hot water) stored is heated to a temperature of 50°C by
means of heat pump operation in the absence of system requests.
The storage tank is only heated with DHW control.

3.15 OUTDOOR UNIT DISABLE FUNCTION

With input active (contact "S 41" Fig. 8), external unit operation is inhibited.
The demands can be met by any electrical resistances appropriately connected and configured.

3.16 DIVERTER VALVE MANAGEMENT (SUMMER / WINTER).

The unit electronics has a 230V outlet to manage the summer / winter diverter valves.
The voltage output is active when the appliance is in Air-conditioning mode.
