Bosch 8733980511 27K 3-zone Mini-split Kit 9K 9K 12K

Product Description

The BOSCH 8733980511 is a multi-zone mini-split heat pump kit designed for residential and light commercial HVAC applications requiring simultaneous climate control across three independent zones. This kit delivers a combined 27,000 BTU/h of capacity and ships as a matched system, including two 9,000 BTU/h indoor units and one 12,000 BTU/h indoor unit paired with a single outdoor condensing unit. The system operates without a line set included, so line sets must be sourced separately. Installation is performed by licensed HVAC technicians familiar with multi-zone refrigerant systems.

This kit is suited for residential retrofits, new construction, and light commercial spaces where a single outdoor unit must serve three separate rooms or zones. Typical applications include multi-room residential additions, small office suites, or mixed-use spaces where independent temperature control in each zone is required. The matched component set ensures factory-verified compatibility between all indoor and outdoor units shipped in the kit.
