Special note :

Don’t see the Kit you need? We have many custom adapters that are not yet shown n the web site. Send us a few Camera phone pictures to”. Please dismount the entire motor assemblyom the damper, and send at least these pictures:


1. Pic of the motor assembly removed from damper, and show us the bottom of the motor as well as the

damper shaft or engagement slot where the motor connected, on the damper its self. We need to see what

adapter will connect to the existing damper can, to then work with the Belimo motor.


2. Pic of the top of the motor, and any brand and model labels that may be visible.


3. A picture of the zone control panel (if there is one) with cover removed, clear enough to see the wiring, as well as a picture of the zoning panel schematic inside the cover.


Send to, and we will advise you of your options.. In most cases, you will end up with a far, far better motor for less cost, than the original factory motor.
