Sell surplus building automation controllers

Selling building automation controllers

What we buy and how it works

We buy building automation and BACnet controllers: network and supervisory engines, field and unitary controllers, VAV and terminal unit controllers, expansion and I/O modules, and the wall sensors and thermostats that wire to them. New in the box from a job that changed, or pulled from a building during a controls retrofit. One controller or every panel from a campus-wide upgrade. Email the model code from each label and a photo of it, and you will have an offer within two hours. The valuation is free and there is no obligation. If you accept, we send a prepaid label, or book a pallet pickup for a large retrofit, and you are paid the day the shipment arrives.

What we pay for

Controllers at every level of the system, from the supervisory engines and network controllers down to the single-zone VAV boxes, with or without their enclosures, base plates and terminal plugs. Also the pieces sold alongside them: expansion modules, communication cards, power supplies and transformers, room sensors, wall modules and the actuators mounted with the VAV controllers. If the HVAC equipment boards, fan motors or drives came out in the same retrofit, send those numbers in the same email.

Brands we buy

Johnson Controls Metasys NAE, NCE, FEC, VMA and the newer M4 and SNC series. Siemens Apogee TEC and PXC and the Desigo range. Alerton VLC, VLX, VLD and BACtalk. Distech Eclypse ECY, ECB and ECP. Schneider, Andover Continuum and TAC Xenta and MNB. KMC Conquest, BAC and FlexStat. Honeywell Spyder and WEBs, Automated Logic, Delta Controls, Reliable Controls and Tridium JACE. Every brand we take is listed below. If yours is not there, send the number anyway and we will tell you either way.

Send the model code and the dash suffix

Building controllers are identified by a short model code on the label, and the suffix after the dash tells a buyer the I/O count, the protocol and the generation. An MS-NAE5510-3 is not an MS-NAE5510-2, and a Distech ECY-303-01 is a specific I/O configuration. Send the code exactly as printed, including the suffix, and a photo of the label. For the supervisory engines and network controllers, say whether the unit still holds its licence or device count, because for those the licence is most of what a buyer is paying for.

New and used

New controllers in the box, left over when a job was re-scoped or a contractor standardised on another line, are the easiest to price. Most of what comes through this page is pulled from buildings during retrofits, and those are bought too. Say which it is. For a pulled controller, tell us that it was in service and operating when removed, whether it has been decommissioned from the site's network, and whether the terminal plugs and base are with it.

Where building controllers come from

Office towers, hospitals, schools and campuses upgrade their building management systems every ten to fifteen years, and the controls contractor comes away with every panel from the old system. Those pallets of pulled controllers, and the new stock on the contractor's shelf from jobs that changed, are what we are asking you to send.
