I have Belimo nrf24a-sz Used on the cooling line. Always variable when temperature rises, sometimes 100% and sometimes 0%. Note that he must be a conqueror
Do you need to set the damper shaft in the open position before powering up? As the actuator will automatically spring return..what if you have the damper shaft/blades on the closed position? Cheers
You always want to perform the pre-tensioning with the damper closed and set the actuator in the closed position without the actuator being powered. Once that is set, you should power it up, and the actuator will go to its commanded position.
@@joemilton7552 it will make a winding noise. Loud would maybe indicate lose parts inside actuator or possibly the kit the actuator is controlling has loose or faulty parts.

Hi we have same actuator and it makes a very loud winding noise when we turn off or turn on the AC. Is this normal?
some noise maybe, very loud noise I would not think is normal

Does it works with 24DC volt or 0 to 10 DC v ?
This video is showing 24 DC voltage. You can contact technical support for detailed instructions on a 0 to 10 DC v actuator.
