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.
• 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.
• SMART GRID INPUT. The unit is equipped with 1 digital contact to manage
an input from the electricity grid. Working logic:
• If the smart grid input is closed, the unit functions normally.
• If the photovoltaic input is open and the smart grid input is open, the unit
deactivates the DHW mode and can operate in cooling / heating mode
for a defined period (which can be set via a parameter), then it will be
deactivated.
• 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.
