Build a multi-room heating and cooling system with the Mitsubishi Heavy Industries SCM100ZS-W, backed by a 5-year parts and labour warranty subject to manufacturer terms. This reverse-cycle outdoor unit supports 3–5 compatible indoor units, with individual room settings through the selected indoor controls.
Outdoor unit only. Indoor units, controllers, pipework and installation are sold separately. Photographs illustrate the SCM-ZS-W family: “up to 5 indoor units” is the series maximum, not the capacity of every model. For this model, use the connection limits below.

Published ratings use the manufacturer's test conditions. Actual performance depends on the connected indoor combination and conditions. Indoor piping sizes, adapters, extra refrigerant and installation clearances must be checked for the complete selected system.
SCM100ZS-W combination restrictions: normally 3–5 indoor units with 9.0–16.0kW total connected capacity. Only manufacturer-approved two-unit combinations are permitted. Five-unit combinations also have indoor-model and capacity restrictions; check the manufacturer's combination table before ordering. Do not treat the connection-capacity maximum as simultaneous delivered output.
Indoor units and controls
Choose only approved models and combinations from the manufacturer's compatibility schedule. Individual room controls and functions vary by indoor unit; timers, economy, high-power, dry and silent functions are not identical on every combination. Professional selection is required for the indoor models, controllers and any optional Wi-Fi interfaces.
