In room heating scenarios, it’s common to hear users complain of cold feet because heat naturally rises. FeetWarm helps to solve this problem by optimizing airflow in heating mode to ensure that the leg zone is consistently heated. In cooling scenarios, FloorSense Cool can prevent the floor area from overcooling by controlling airflow and cooling capacity so that the air at floor level does not get as cool as air above knee height.

 The CO2 emissions coefficient is 0.441 kg-CO2 /kWh. Based on Electric Power Industry Council for a Low Carbon Society in FY20.
 Comparing Hitachi Set Free Sigma 28HP system with air365 Max 28HP system. Similar footprint reductions achieved across all capacities.
 Conventional way to open and close the cover and manipulate dip/power switch takes 40min 40sec. By using airCloud Tap without opening the cabinets: takes 9min 40 sec. [Simulation scenario] total 4 ODUs initial setting. total 5 items setup; ODU number, Refrigerant cycle number, Higher ESP setting, Power Supply setting, and Compressor manual-off setting.
 Conventional way takes 103min 16sec. By using airCloud Tap: takes 47min 40 sec. [Simulation scenario] Total 20 controller setting. Total 7 items of setup: Room name, Time, Language, Temperature unit, Backlight of the screen, Operation schedule from Monday to Friday 08:30~18:30 28°C , Upper and lower limit of setting temperature for both cooling and heating.
 Test simulation scenario: Check the alarm cause. [Previously] open up the cabinet panel, open the electricity box cabinet panel, check the PCB error code, close the 2 cabinet panels. Requires minimum 3mins. [with airCloud Tap] open the airCloud Tap application, TAP the outdoor unit to access all settings and download operational data. Requires approx. 30secs.
