room temp/auto & longer blower time.

[Tonyray]

ok... when I run my Harman on room/auto the distribution blower will keep blowing into the room even when the flame ramps down and close to just embers in the burnpot.
on that setting it's like the stove is squeezing every bit of heat it can into the living space
as opposed to room/manual where when the flame starts to ramp down, the distrb blower shuts off Much sooner and It's sending any and all heat right up the exhaust and all during maint burn or what I Call simmer mode for quite sometime... I have used room/manual many times but it seems as if room/auto puts heat into the room for much longer stretches than in manual mode. [at least now during shoulder season]..

 

[F4jock]

Doesn't do that for me. I think in that mode, which is the only way I run, the distribution blower run time is based on a combination of room temperature and ESP temperature.

Have you cleaned the ESP lately?

Probe is always cleaned..
not saying I have a problem here..
saying that in room temp/auto the distribution fan puts heat into the room longer period of time than manual mode with settings being the same.
In manual the blower stops lot sooner..
example:
when the flame is starting to ramp down and the dist blower is still pushing heat into the room,[room/auto], if I put the switch into manual, the blower stops running while the flame is ramping down.

Hmmmm, curious. With mine I've never noticed a difference but I've never given a thought either.

In room temp manual the stove tries to give you and exact temp within 1 degree so the fan kicks on and off to achieve this. In room temp auto there is a 4 to 5 degree diff so the stove can shut down and not have to cycle back on again for some time, so the fan will expell any heat left in the stove into the room until it's shuts down. At least that's how I perceive it?

has too be some kind of [ additional]advantage to the room temp/auto mode because it spends more time blowing warm air into your room than it does sending it all out the exhaust while it's running as it does in room/manual when flames start to ramp down..
another way to look at would be in manual mode, your stove could be in maint mode for an hour and the whole time every bit of the heat is goin out the exhaust the whole time.
in Auto, the stove would be off.

Both of mine do that too. Wasn't a big deal with the P61a last year since it doesn't have to keep a large area warm. In fact I had noticed it but never really thought about it. But with the P43 needing to keep the whole upstairs warm, I'm beginning to think I can't run it in room temp/manual as the bedrooms need warm air pushed to them at all times or the cold will creep in from the garage.. When the really cold temps hit, I will have to experiment with stove temp since I hear the distribution fan keeps going in that mode. Hey, the room temp/manual might work once the cold hits too. Right now I'm using room temp/auto anyway since we haven't been consistently cold, and if the sun is out it will warm up the house fine in the afternoon.

I'm an old, skinny female that was born and raised in the 110* Kansas summers. My house loses a ton of heat thru the non-solid tiles that should be sheetrock for the ceiling.

Once you start paying for my pellets, you can question my useage all you want (said in good humor)

 

[Cory S]

I would sell the house as fast as I could..... Plus $27.xx tax rate in Hillsboro ugh....

 

[bogieb]

Better tax rate than Deering (where I used to live). No selling this house for a while. Working on it is how I pass my time and money.

 

[Cory S]

I think Antrim is close also.

Interesting observations gang. I tried running my stove in room temp manual for a very short time but went back to auto almost immediately. Didn't really notice if the fan stayed on longer. I do know that my fan ramps down as the flame dies until, when it's just a glow or very low, it quits all together. In any case I'm happy with room temperature and have only gone through one igniter in eight years so there it will stay!

 

[Cory S]

Stove temp auto FTMFW.!

 

[Tonyray]

As the OP, the stove temp/ room temp are usually the most discussed.
many run room/manual simply due to the stove never shutting down and having to re-ignite many times per day.
I subscribe to that method but at the same time. I want the most heat going into my room as opposed to going up the chimney.
not an authority here but room /auto seems to keep blowing heat into the room till the cows come home or close to shutting off.
on the other hand, in the coldest part of winter, room auto will not shut down either [in my house] so have to expiriment this winter again.
also, saving the Ignitor[ $70.00 Ebay] is not a reason enough for me to strictly use manual mode.
never used stove/auto so like to hear thoughts on that concerning distribution blower running longer or not.

Room temp manual is for someone who doesn't want the stove to shut down and give a temp within one degree the fan guaranteed will cycle on and off to achieve your 1degree set temp, room temp auto is for someone wanting their stove to shut down after set temp is reached, the fan will run continuously until the stove cools enough to go into shut down and the temp diff of 4 to 5 degrees between start up and shut down. I like room temp manual because it maintains the set temp within 1 degree, I don't like the 4 to 5 degree swing being hot and then cool before the stove turns back on. Yes their is heat loss when idling but I'm more comfortable literally speaking in room manual.

 

[DOLLARBILL]

For me it depends on the time of year early on like now when the days a still warm I use the Room/ Auto setting ,as it gets colder I switch to Room/manual I want that thing running 24/7 and I like the idea of saving the ignitors ! To each his own !

Interesting. The largest delta T I get using Room Temp Auto is 2f and that measured on my Dino Thermostst twenty feet from the stove. There is a dipswitch setting on my board that, when on, supposedly gives a 1 degree delta at the room sensor.

Ran the P43 in stove temp / auto last night as the cold from the garage was seeping up into the bedroom but the living room was within the set point so the stove wasn't firing. In stove temp / auto, the distribution blower stayed going at the level I specified (high in this case) so the air was blown down the hall into the bedroom. Nice and warm in the bedroom this morning even though the temp was 18* when I got up this morning (truth be told, it was a bit too warm, so will experiment more). If it had been in room temp / auto, the room would most likely have been in the mid to low 60's. Not worried about the igniter as the P61a in the basement is in room temp / auto until the real cold hits so I know it isn't an issue.

EDIT: Turned the stove back to room temp / auto a couple of hours ago. Just went to check the bedroom temp and it is already down to 67.8*. Don't want to think what it would have been this morning if I had left the stove on the same setting all night!

Well your an anomaly lol.

F4 when it's 50* outside and I have the stove in room/auto it will kick on guessing about every 2 hours to maintain my set temp. If my stove was maintaining a 1 or 2 diff on the t-stat in room auto, it wouldn't ever completely shut down when it's 50* outside. How often does yours cycle with only 1to 2 degree diff on the t-stat

My wife would agree!

Depends on the outside temperature. Right now it's 38 and the stove cycles about once an hour. When it gets into the twenties it's twice an hour and low twenties the distribution blower will ramp down to off but the stove never really goes out. Also, my blower ramps from full to off pretty smoothly over about five minutes.

It took me a month of playing with the room temp sensor to figure out where to place it so that the room stayed at an acceptable temperature. Unlike many I'm not trying to heat the whole house with the stove, just the living and dining areas which are quite open. I have zoned heat and use the oil burner for the bedrooms. Perhaps that is the difference in that I'm not trying to push heat down the hall and all over the house. Also have a ceiling fan in LR. We like it cooler than most, keeping the temperature between 68 and 70.

We have a South facing window wall in the main living area so when it's 50 outside if there is any sun stove is off until after dark.

 

[Cory S]

We like it 67-69. 70 is a bonus, but anything higher than that, and it feels just a little too warm.

ok.. most replys are preferences which doesn't get to the answer so I'll give you a shot since your explanation is good.
In room/auto right now and the flame is ramped down to few inches above the pellets..
dist blower is still pushing very hot air into the room..
now if I switch to manual, the blower shuts off and all that hot air is NOW going out the exhaust into the chimney.. ESP probe is satisfied I am told.. ok.. get it.
I prefer that the hot air still be pushed into my room so tell me why I would want to use room/manual [excluding] the obvious reasons of " stove will not shut off/faster recovery" and "less Igniter wear"... the blower keeps going longer in room/auto as u described.
