Convection Fan Operation

Convection Fan Operation

PostBy: Warm_InKulp On: Tue Jan 06, 2009 12:20 pm

Hi, I just recently purchase a Pioneer LE top vent and I am really impressed with it so far. :) :D

The one question I have is in regards to the convection motor and how it is suppose to operate.

Min setting of 8
Max setting of 40
CFT setting of 6
Day temp of 74
Night temp of 68


In the morning, when the temperature is suppose to change from 68 to 74, the stove starts to heat up as it should, the conv fan however never goes above what I would consider to be %10 of it full speed, you can almost see the blades on the fan since it runs so slow. I can manually change the speed all the way to %99 and it will run accordingly, but in auto mode it never seems to go above %10 no matter how hot the stove gets. One other thing I noticed, it also will turn the conv fan on full speed for a burst of maybe 3-5 seconds 3 or 4 times in a row, then settle into the %10 speed mentioned above.

Should the convection fan operate like this?

Where's your thermostat located in regards to the stove.

Fan speed is based on FEED Rate, the temp swing is probably too much and you don't give it enough time to catch up or your house heats up fast enough to satisfy the thermostat and the fans don't need to be put up to full. Mine will only run at full when I start getting up into the 80-95% Feed rate.

Check your FR (feed rate) to see what it is doing, the Fan rate is based on Feed Rate. If your Feed Rate is 50 or less, your fans probably won't be running full.

if the Blowers kick on/off full speed a couple times, that is normal (Look under the CoalTrol section V3 Features), also, you might be at the Threshold of the FR vs. CFT, it will do that sometimes ( This has been discussed in the CoalTrol Section too ).

We have all discussed the Temp. Setback and most of us don't use it, or only a couple degrees at a time.

Thank you for the reply and the attached links, they were very helpful :)

The Thermostat is located on an adjacent wall roughly 12ft from the stove...only place the I could put it.

I understand what you are getting at as far as the room heating up before the feed rate has a chance to go high enough for the fan to run at a higher speed...I guess it is something I will have to live with :( I think I will monitor the FR tomorrow morning to just see how high it goes and its relationship to the convection fan.

I am not sure why everyone does not like to use the set back for more than a few degrees of adjustment...it seems to work fine for me where I have it set.

I'm not sure if there is a problem or not. You can make a direct call to ED at Automation Correct (coal -trol) and get the info right from the horses mouth. 315.299.3589 Tell him I told you to call.

Sounds like there's nothing wrong, just the way it works.
if your setback is working for you, Great! I guess it depends on your stove location and thermostat. Mine is in the basement, and have a big house, so it takes a while for it to get going and then overshoots. That's why I keep it a constant temp. :)

I had the same issue the the conv fan when I first ran my LL Econo. I spoke with the folks at Coal-Trol and they had me turn down my MAX. Now my max is at only 25 and my fan comes on more often. I have a small, well insulated house. Best to get it from "the horses mouth though" . CoalTrol was very helpful and helped me better understand the way the thermostat works. I keep my thermostat at 70* all the time.

Thanks for all of the responses.

I believe WNY was correct, the room I have the stove in heats up to quickly and the feed rate and conv fan never really have a chance to go into 'high gear". As an experiment this morning, I left the door open a bit to prevent the room from reaching the set temp...and sure enough, the feed rate and convection fan worked as it should :)

Being new to the coal stove community, I guess I am a little bit paranoid as to how things work, this forum has been a wealth of information and I am glad I found it.

Also that is a big difference between your night and day temp i usually run mine the same or 2 degree difference because it take's a long time for it to adjust thats one thing i don't like about burning coal its a slow process... I guess it depends on your house and stove location etc just a FYI..
