The Integer Link

One box to connect your installation.

The Integer Link is the controller behind Optimize and Optimize Pro. It connects to your BMS or directly to your equipment, and links your installation securely to the Integer platform.

Installations

With or without a BMS.

With a BMS

The Link works on top of your building management system as a supervisory controller.

Integer CloudInteger Link BMSBuilding HVAC
Your BMS keeps its own control and safety logic.
Without a BMS

The Link connects directly to your equipment: it reads data and adjusts setpoints and operating modes.

Integer CloudInteger LinkBattery AHUPV Radiators 530ppm Climate sensors
Each component keeps its own control and safety logic.
Or mix both.
Connect the Link to your BMS and add individual components to the same Link, like wireless radiator valves or climate sensors.
FAQ

Frequently asked questions.

Have another question about the Link?

Get in touch
Can I use my own internet connection?

Yes, no problem. The Link can be configured to connect to the internet over wired Ethernet instead of its built-in 4G.

What if the internet is down? Will the Link still work?

Yes. The Link falls back to local control, so your installation keeps running. While the connection is down, you will not see the latest data in the Integer platform.

Does the Link need access to our IT network?

No. With its built-in 4G module, the Link has its own connection to the Integer platform, separate from your IT network.

What happens if the Link is switched off?

Your BMS and components keep their own control and safety logic, so the installation simply carries on as it did before.
