Hydraulic unit with 3-way diverter valve for DHW production supplied as per standard

Water/gas exchanger with brazed stainless steel plates

Low consumption system circulator with brushless DC motor

Automatic air vent

Water differential pressure gauge

Water pressure gauge

Expansion vessel

Safety valve

Y water filter supplied as per standard (mounted by installer)

 

The control system

Comprised of a wired-remote digital controller (max 50 m from the I.U).

HEATING AND COOLING SYSTEM: the compressor frequency is modulated to keep the temperature of the produced water at the established setpoint value. For single-zone systems the control unit can operate as a room thermostat.

DOMESTIC HOT WATER (DHW) PRODUCTION: upon request of the DHW temperature probe (supplied as per standard), operation is activated in heating mode to maintain the temperature of the DHW tank at the established setpoint value.

ADDITIONAL ENERGY SOURCES: the electrical integration boiler or booster, if any, can be started in Integration or Replacement of the heat pump and also if the heat pump is not working.

ANTILEGIONELLA FUNCTION: weekly antilegionella cycles can be set. The heat pump must be integrated with DHW storage tank or boiler electrical heater.

FAST DHW: this function prioritises DHW by activating all the energy sources available to bring the DHW storage tank to the established setpoint in the shortest possible amount of time.

SILENCED MODE: according to a programmed schedule, this reduces the maximum frequency of the compressor and the fan speed, to reduce the generated noise and the power absorbed by the unit.

ON/OFF REQUEST: the unit can be switched on and off by an external contact.

HEATING/COOLING REQUEST: the unit can be started and stopped in cooling or heating mode by 2 external contacts (e.g. zone thermostat that manages the request for cooling and heating / remote switch).

ECO: possibility of defining a time slot in heating mode where the heat pump runs with a sliding setpoint defined by the chosen climatic curve. There are 8 climatic curves for low temperature systems (radiant floor) and 8 climatic curves for fan coil or radiator systems)

WEEKLY SCHEDULE PROGRAMMING: this makes it possible to set a different schedule for each day of the week defining the operating mode for each time slot (COOLING/HEATING/DHW) and the work setpoint.

Antifrost protection. Guaranteed down to -20°C outdoor air temperature thanks to the heat pump itself. Working in heating mode, for the electric antifrost heater (as per standard) and the electric booster (if installed).
