Up to 16 air conditioners. One wall screen.
Up to 16 air conditioners. One wall screen.
Nexus Multi puts several standalone air conditioners on one wall screen and in the free AirNexus app. The screen is the controller: the Central Controller and the 4 inch Room Controller each have their own processor, so there is nothing else to fit.
An FCU Gateway connects each air conditioner at the unit's own control terminals, with a 2-core data cable back to the screen. Up to 16 units, from split systems and multi-split heads to ducted units and fan coils, with compatibility confirmed for every unit at quote stage.
Each unit gets on/off, mode, fan, setpoint and room temperature, plus its fault codes in plain English in the app.
The kit is the screen: pick the one that suits the site. FCU Gateways are sold separately, one for each air conditioner.
