Airnexus

New: reliable push-notification automations, plus a faster, more stable app across all your zones. Update today.

AirNexus turns any home or building into a precision climate system — every room, every zone, controlled from your pocket or from anywhere in the world.

Built for ducted air conditioning, VRV/VRF systems, hydronic heating and fan-coil units, AirNexus gives you room-by-room comfort that ordinary thermostats can't touch. Set the temperature you want in each zone and let the controller do the rest: balancing airflow, staging heating and cooling, and proving the system is actually delivering before it opens a single damper.

WHOLE-HOME, ROOM BY ROOM Control up to 32 independent zones from one beautifully simple app. Mix damper zones, hydronic circuits and individual fan-coil units on the same system — each with its own temperature, mode, fan speed and schedule.

WORKS EVERYWHERE — EVEN OFFLINE Control your system from the couch or from another continent over a secure connection. On-site, the controller keeps running your schedules and comfort settings even if the internet drops. No cloud outage takes your heating offline.

SMART SCHEDULES & AUTOMATIONS Set warm mornings and cool nights per zone with simple day-and-time schedules. Create if-this-then-that automations from live system data — trigger a zone, stage a pump or push yourself a notification when a temperature crosses the line.

WORKS WITH YOUR SMART HOME Pair with Apple Home, Google Home and Amazon Alexa over Matter, and integrate with Control4 and other professional systems. Ask your voice assistant, tap a HomeKit scene, or build it into whole-home automation.

HYDRONIC & PLANT CONTROL Drive zone valves, pumps, ring-main circulators, backup heaters and mixing valves with weather-compensated heat curves. Monitor heat pumps, buffer tanks and solar inverters right alongside your zones.

SEE EVERYTHING Live diagnostics show exactly what your system is doing — damper positions, airflow, supply and return air, sensor readings and a full change log of who changed what and when. A live I/O board shows every input and output in real time.

BUILT FOR INSTALLERS, LOVED BY OWNERS Fast on-site commissioning over Wi-Fi, deep installer configuration, and an interface clean enough that anyone in the house can use it.

AirNexus — comfort in every room, control in your hand.
