Bosch 8733980505 27K 3-zone Mini-split Multi-zone System

Product Description

The BOSCH 8733980505 is a multi-zone mini-split system rated at 27,000 BTU/h, designed for residential and light commercial comfort applications requiring simultaneous climate control across three independent zones. This kit includes one outdoor unit and three indoor air handlers configured as one 9,000 BTU/h unit and two 12,000 BTU/h units. Licensed HVAC technicians install and commission this type of system, which uses inverter-driven compressor technology to deliver variable-capacity heating and cooling without ductwork. The system ships as a matched component kit, ensuring factory-verified refrigerant circuit compatibility across all indoor and outdoor units.

This three-zone system is suited for residential applications such as multi-room retrofits, additions, or new construction where running ductwork is impractical. It is also appropriate for light commercial spaces requiring separate zone control in individual offices, server rooms, or retail areas. The kit covers zones of varying size by pairing one smaller 9,000 BTU/h indoor unit with two 12,000 BTU/h indoor units, allowing flexible layout configurations from a single outdoor condensing unit.

• Ductless design eliminates the need for forced-air duct infrastructure
• Three independent zone control supports simultaneous, separate temperature settings per room
• Factory-matched components ensure refrigerant circuit and control system compatibility

Compatibility

This kit is a factory-matched multi-zone system. Indoor units included are part numbers 8733962672 (qty 1) and 8733962673 (qty 2), paired with outdoor unit 8733962700 (qty 1). Do not substitute indoor or outdoor components without verifying manufacturer-approved combinations.

Installation Notes

Installation must be performed by an EPA 608-certified HVAC technician. Shut off all electrical power to the installation area before beginning any wiring or refrigerant line work. Refrigerant line sets, electrical disconnects, and control wiring must be sized and installed in accordance with the National Electrical Code and local mechanical codes. Do not mix matched kit components with unverified third-party indoor or outdoor units, as this may affect system performance and void manufacturer coverage.
