Multi-point sensing uses thermistors in the indoor unit, the remote control, and the outdoor unit to get a complete picture of your home's climate. This allows our Single-Zone units to adjust their output with incredible accuracy. For those with a Bravo Milano 9,000 BTU in a bedroom, this means the temperature stays exactly where you set it all night. In a Penta-Zone system, these sensors coordinate to prevent any single room from over-cooling. Using the high-speed data cables in our Installation Kits is essential for this sensor data to travel correctly. If your remote isn't sensing correctly, you can find replacement controllers in our Other Accessories catalog. This smart network is the "brain" that keeps your Bravo Milano system running efficiently.
