The new i-NRG heat pump provides exactly the energy required by the system, perfectly following the real load of the building, thanks to the
modulation of the DC inverter fan. One single unit for the highest efficiency, sustainability and huge savings, thanks to the advantages of
DC frequency driven fans and circulating pumps (inverter) for both plant and domestic hot water circuits. i-NRG is the new generation heat pump for all year round operation in any operating mode: single cycle (air conditioning, heating, domestic hot water) as well as combined cycle in total heat recovery (domestic hot water together with cooling). Domestic hot water production is guaranteed by the dedicated exchanger for heat recovery: total, for free domestic hot water production, or partial.
Domestic hot water is stored in a properly dimensioned storage tank.
The unit can be installed indoor or outdoor, thus ensuring complete flexibility. Extended operating limits for all year, specially in heating:
-Maximum flow temperature 60°C
-Maximum external air temperature 45°C
-Minimum external air temperature -15°C
Electronic control Nadisystem provides great application flexibility. The remote keyboard kit wired indoor and outdoor temperature sensors allow dynamic control of delivery temperature water, optimizing comfort in the room and increasing the energy efficiency.
The electronic board allows you to manage:
-Wired remote control, backlit display complete with remote temperature and humidity probe
-outdoor temperature sensor for water plant side modular set point compensation
-a zone of direct heating for radiator, floor heating or fan coil
-a zone with mix valve for floor heating
-electrical heating element for possible integration and anti-legionella cycle for cylinder
-boiler or electric heater in substitution or in addition
-the room controller can customise up to six time bands. The presence of the programmable timer allows the creation of an operating profile containing up to 6 time bands
-up to 4 heat pump in cascade (with N-CM component)
-several solutions through appropriate configurations of the controller and use of dedicated extension modules (accessorie), up to 5 zone
The defrost adopts a proprietary self-adaptive logic, which features the monitoring of numerous operational parameters. This allows to reduce the number and duration of the defrost cycles, with a benefit for the overall energy efficiency.
