Seton Damper Actuator (Belimo)

[JMann]

I am all but finished with my setup. One thing has me stumped. I have the power hooked up to a plug and connected to the outlet and the Damper Actuator plugged in (Belimo 120).

I'm not sure how the actuator works. It has the damper and vents shut and does not seem to respond when starting a fire, hence no draft, no fire. Can someone help me out on this one?

The Belimo is controled by the #1 aquastat, with low water temp, the #1 aquastat makes closes the curcuit and gives the Belimo power to open the damper door. High water temp. the #1 aqustat opens the curcuit and the belimo closes the damper door. hope that helped. double check your wiring

Will do, thanks. It came pre-wired.

Keep us posted on the Setons performance as well as learning curve. Some pics would be nice.
Thanks

I called into Bethel Engineering to discuss the issue with the damper actuator (this is controlled by aquastat #1). The sales person that I spoke to explained that the wiring was set incorrectly at the plant before it was shipped. Attached is a .bmp file showing the correction (simple).

check the installation of your belimo,you may have it in backwards. the horseshoe clamp faces outwards. when i installed my seton i almost made that misstake.

I put it on backwards at first. It didn't seem right, so I switched it. I can;t find anywhere in the manual about it. Does your actuator totally close at times? Mine gets close, but never shuts the full way.

you need to set it so when it shuts its pushing against the boiler and the motor winds hard just at the end.

Thanks, I'll be doing that tomorrow when it cools down. I've got to get the kinks while it's still warm.
