Bosch IDP Family. Featuring all of the benefits of the Bosch Inverter Ducted Split systems in a single package, the IDP offers best-in-class efficiency and comfort. Each system in the IDP Family delivers premium comfort and performance by adjusting compressor capacity rather than a simple on/off control like other traditional units. This customizable feature allows you to bask in comfort while still reducing operating costs and saving money. The system also works seamlessly with your thermostat to automatically adjust to your preferences. Plus, integrated sound dampening features keep the unit nice and quiet all day long.
