Eco-mode is a specialized operating frequency that limits the power consumption of the compressor to save money on utility bills. It is highly effective in our Bravo Milano 24,000 BTU Universal Floor/Ceiling units during the mild months of spring and fall. In a Tri-Zone setup, activating Eco-mode on one head can significantly reduce the overall draw on the outdoor unit. To monitor your energy savings, you can pair the system with smart WiFi Accessories from our store. A level installation on a Wall Bracket ensures that the inverter logic can accurately calculate the most efficient motor speeds. This mode is the reason why Bravo systems are some of the most budget-friendly HVAC solutions on the market. It allows you to maintain comfort without the "bill shock" of traditional central air.
