I just installed a Zone Control system today. Everything is working as it is intended although I have a question about the Dampers. They are closed dampers. When the system is on the are constantly receiving power and charged, just always maintain a open position. When the zone requires heat it shuts the other zones off and only the required zone is receiving heat. When the Zone is heated the furnace will shut off and all Dampers return to the open position.

They are wired in the Common and Open part of the board. The board has 3 wiring areas. Open, Common, Closed.

If I wire it in the closed are so the Dampers are not always powered the opposite happens and the zone needing heat closes itself off and the rest open. This way the dampers are closed and not constantly powered. This makes sense to me why it does this.

My question is, are the dampers suppose to always be powered on? and shut off when the zone shuts off for heat?

As I said it is working perfectly this way but it just doesn't make sense why they would always be powered and open. Not remain shut and open as needed.

Insight is appreciated.

Cheers!

Looking at the dampers from homedepot, they appear to be normally closed (non energized) and then open from being energized, as you stated. So the way you have them wired on the common and open is correct, and the fact that they function correctly when the furnace is operating. But they seem to all get energized into an open position and remain that way when there's no longer any calls from the hvac equipment?

Have you timed this to see how long this lasts? I know there's a time delay feature in that controller that will open all the dampers when everything is satisfied. I would check all settings to confirm your equipment is setup correctly. Post your other equipment also.

Ill try to explain this the best I can. So this system I attached to a Oil Fuel Furnace. I do plan on upgrading in the future but my house is drafty in the bedrooms. So to maintain 71* in the bedroom the living room would be 80*. So this is actually since installation is working out fantastic until I reside and seal my entire house. Thermostats were installed in each room previously to keep the bedrooms at temperature due to a newborn last year. Now I Zone controlled the system to help conserve fuel for the time being.

Besides the Zone Control Board and dampers linked. The Oil Furnace Model is: LLO7085BGA1OLM085B14A1
Style No: MBO-85-DB

You are correct. The open on the Control board by Default is energized, thus all the dampers are always powered open. When there is a call for heat 3 zones shut off and the dampers close to to NOT being energized. The damper that requires heat never loses energy and remains open. There is no delay and this is always on.

I have ran through the set up for the equipment multiple times and at least as far as I can tell this is normal operation. It absolutely could be set up the way it should but from my novice perspective always staying energized doesn't make sense.

I did try wiring it to the closed section. By default Closed is not energized so all dampers are closed. But when a Zone calls for heat the 3 zones are changed and the closed one remains closed. Thus rendering the system to perform opposite and all zones not needed heat are opened .That's why I think its wired correctly now but I am second guessing myself even though its working as intended. Just the zones are always energized.

They are 2 wire dampers. The board can take up to 3 wired dampers.

Thank You for the input
