2.3 User interface
The user interface consists of a digital controller built into the indoor unit which
allows you to control:
• HEATING AND COOLING If the unit is activated in heating or cooling mode,
it works by modulating the compressor frequency to maintain the produced
water temperature at the set point value set by the controller.
• HEATING WITH BOILER. It can be activated in integration or replacement of
the heat pump based on the set parameters. The board will also activate the
boiler if the heat pump does not work.
• ELECTRIC HEATER DHW TANK . In DHW mode, it can control an electric
heater inserted in the DHW heater to integrate the heat pump. The DHW tank
electric heater is essential for the photovoltaic input function.
• FAST DHW . This function can be activated manually that allows you to give
priority to the domestic hot water by activating all the energy sources (heat
pump, electric resistances, boiler) available for DHW heating to bring the
DHW tank to the set point in the shortest possible time.
• ANTI-LEGIONELLA FUNCTION. It is possible to set anti-legionella weekly
cycles from the controller. In order to carry out these cycles correctly, the heat
pump must be integrated with the DHW tank or boiler electric heater.
• SILENT MODE . If active, it involves a reduction of the maximum compressor
frequency and fan speed to reduce the noise emitted and the power absorbed
by the unit. There are 2 levels of silencing. Through time programming, it is
possible to define the desired silencing level for 2 daily time bands (e.g. at
night).
• ON / OFF via an external contact. The unit can be activated and deactivated
(e.g. zone thermostat / remote switch) via an external contact: in this case the
unit will operate in the way set via the controller keyboard.
• HEATING / COOLING via external contacts. The unit can be activated and
deactivated in cooling and heating mode via 2 external contacts (e.g. zone
thermostat that manages the request for cooling and heating / remote switch).
• ECO . Possibility of warmly defining the time bands and relative setpoint for
the ECO mode.
• WEEKLY HOURLY PROGRAMMING. This allows differentiated hourly pro-
gramming for each day of the week, defining the mode (COOL/WARM/DHW)
and operating setpoints for each time slot.
• ANTIFREEZE PROTECTION . It is activated if the water temperature meas-
ured by the temperature probes present in the indoor unit falls below 4°C: it
provides for the activation of the internal circulator and possibly the heat pump
in heating mode and/or the boiler.
• MANAGEMENT OF UP TO 2 ZONES (1 mixed and 1 direct). The unit is
able to manage the pumps of both zones and. for the mixed zone only, the
mixing valve and the water delivery temperature probe.
• SOLAR THERMAL MANAGEMENT . The unit is able to manage the solar
pump and the temperature of the solar collector.
• PHOTOVOLTAIC INPUT AND SMART GRID INPUT . The unit is equipped
with 2 digital contacts to manage an input from a photovoltaic system and the
grid. Working logic:
• - if the photovoltaic input is closed, the unit activates the DHW mode with
DHW setpoint = 70°C and will activate the electric heater of the DHW tank
(if installed). The unit will continue to operate in cooling / heating mode with
the normal logic set.
• - If the photovoltaic input is open and the smart grid input is closed, the unit
works normally.
• If the photovoltaic input is open and the smart grid input is open, the unit
can support the system in cooling/heating mode for a defined period (which
can be set via a parameter), then it will be deactivated. The heating of the
DHW water heater will, on the other hand, be guaranteed only by the used
of the boiler.
• CURRENT LIMITATION BY PARAMETER.
• REMOTE CONTROL OF THE UNIT VIA APP (available for IOS and An-
droid).
• DETAILED ERROR DIAGNOSTICS WITH HISTORICAL ALARMS.
• DISPLAY OF ALL OPERATING PARAMETERS.
