Controls for every HVAC unit. Every major brand. One controller.

Controls for
every HVAC unit.
Every major brand.
One controller.

AirNexus builds controls for the HVAC you already have. The Nexus controller connects to your air conditioning, hydronic or geothermal system, whatever the brand, and puts every unit under one set of controls: temperatures, modes and schedules, plus live faults and energy use in the Nexus iQ dashboard and the AirNexus app. For building owners, facility managers and the HVAC contractors who look after them.

Supplied by AirNexus

The Nexus controller, add-ons and Nexus iQ, direct from AirNexus or through an authorised partner.

Installed by your HVAC contractor

Your contractor connects it to the control network the system already uses.

Works with your existing system

It sits beside the system you have, whatever the brand. Your units and controls stay as they are.

Nexus iQ is a subscription

Keep it active and your Nexus 8, 16 or 32 carries a lifetime warranty.

How it works

Plugs in. Reads everything. Reports to you.

1

The Nexus controller sits beside your system

It connects to the control network your air conditioning already uses, any brand. About the size of a small router.

2

It reads every unit on the network

Daikin, Mitsubishi Electric, Samsung, LG and eleven more brands. Up to 32 indoor units on one controller.

3

You watch and control it from Nexus iQ or the app

Temperatures, set points, faults, health scores and energy use, live. Switch units, set schedules and get alerts on your phone before anyone in the building notices.

AirNexus supplies the controller and the Nexus iQ platform. Your existing system stays exactly as it is.
