Oh ok.. I do have a AOT button. It is set on 1, which is the factory setting. But I don't know what that setting does. I just heard leave it alone.

And 1 is where it should be.
ETA: It sets the temperature at which the convection system will be turned on.

I have the same stove, and on setting (feed rate)1-1(blower speed) and 2-2 it runs with blower on quiet and never really hear it, then when i turn it up to 3-3 or 4-4 on cold nights i mean in teens outside, then the blower once in a while with go max it seems for a couple minutes, but i always thought that was normal as i thought it was just that the stove temp got too hot and the blower kicked in too cool the stove and restore it to a 3-3 level, as on the numbers its still set to 3-3 even thought the blower changes speed to higher to what i thought was to cool the stove down.

Hmmm.... This is interesting.. That makes three of us. I bet there is more.
When I talked to Mike H a couple days ago he talked like he had never heard of this issue.

Yes but there is some question about weather it is doing that normally or not, in the cases where the convection blower has been turned above the firing rate I would think it would be a rare occurrence.

Does anyone know the flow rate of the convection blower on that stove?
I didn't see it in the manual, but then I only read through it quickly.

Pulled from the parts section on the website.
PU-4C442 Convection Blower (6 lbs. each)
$130.98
Convection (Room Air) Blower. 140 cfm.
EDIT: Looks like a larger fan is used on 2002+ and “deluxe†models? That fan is 250cfm.
I don’t know what I have…

Be careful as that applies to other than your EP which is not one of the listed units that have a deluxe setup.
Wish Mike would chime in.
The 140 CFM should be fine if the airflow curve is correct in the controller. You haven't left any of the exhaust channel covers open have you that might allow hot exhaust gases to bypass the heat exchanger.

Yea your right. I went back and re-read it. Mine is 140cfm.
Mike will get this figured out. I'm sure he is busy with lots of other stuff.
No, I put the exhaust inspections covers back just like they were.
i had the same issue when i first bought the stove.
worked with mike and loosened the thermocoupler ( not sure if correct term) bolted on top of the exhaust blower and added a washer underneath. if i keep it loose it works fine.

I have been talking with Mike.. He suggested the same thing. I did it last night but it didn't seem to make any difference. Although I did not leave the bolt loose.
He wants to talk with the engineer that is out because his wife had a baby. Waiting on a answer from him.
Putting a washer underneath is a way of making a heat sink, I think. And leaving it slightly loose helps accomplish that, allowing some air to seep in and cool the thermocouple slightly.....that will make the fan go back to regular speed.

SmokeyTheBear said:
Not sure what you mean Smokey, but increasing the LBA will help too.....only issue is that raising it too high just results in sending the air through the heat exchanger too fast and right up the exhaust.

The controller has a table somewhere that controls the speed at which the convection blower rotates, if this is changed to increase the rotational speed a bit higher at each firing rate it will remove more heat from the heat exchanger and the exhaust stream. Thus the TC will read a lower temperature.
This is an equivalent fix to what you are proposing without the possible issue of sending the heat out the flue. It however must be done at ESW and not by the owner.
The other thing that can be done is to install a slightly larger flow rate blower say a 160 CFM one, this raises issues surrounding cooling the exhaust down too much or having it actually heat up because of pushing air through the manifold too fast than it can use to extract the heat with. However I don't think that the additional 20 CFM will make that happen, but then I don't know. Mike is correct going back to the engineer on this one.
GrahamInVa said:
I didnt like that as a fix either. Seems to work just fine and still triggers the high heat blower if it gets to that level.
We tried many adiustments on the panel to no avail....
If there is a factory fix ( maybe new thermocouple) let me know if anyone hears of that. I have 1 month left on my warranty

I loosened the bolt that holds the exhaust temp sensor to the exhaust outlet. I tried hard to get it to overheat and kick that room fan on max but no avail...
I tighten the bolt back up and I will wait for word from Englander.

I dont think there is an issue here at all, IMO. How do we know there is "a bad batch of boards"? Is that just a blogger's point of view or is that straight from the manufacturer's R&D department? Worse thing a manufacturer can do is deny a problem, mostly they embrace them and fix them in a reasonable amount of time. I work for a major manufacturer (not pellet industry) and when we make a mistake the worst PR thing we can do is ignore it or deny it. I have an EP, second EP I have owned. Both of them would raise the convection blower when I had decent pellets. When running crap pellets this would never happen. I do not think it is an "overheat" condition. I believe it is an intention part of the program. Does any of you who have experienced this condition have a control board that has been replaced but not yet sent back to Englander? If so I am fully willing to interrogate it and provide "real world" data on it's setpoints. Instead of speculation by a lonely blogger.
There really is NO DISADVANTAGE to an EP stove pushing the room air blower to high. The EP has such an nice heat exchanger that running the convection on anything less than high is a waste of fuel. Remember, we bought a $1600 stove, not a $3500 harmon
