Harman P61 Esp light on fan on full

[Spaz]

The Harman can do 1F swing in room mode (with a properly located probe), if it runs in idle mode, in winter, when it's always heating. Once you shut it off, and restart, it will swing like you say.

I did a test on that, and you must be right, it took longer to heat it up then it ran. So no more room mode, back to the stove mode where it can run for hours on end. The Quadrafire is the same, it will come on, go off, come on, go off. The sensor on the Quad is 10 feet away which means it takes 45 minutes to move it 2 degrees on a colder day. It's in the 40's right now. So fire up the Harman before bed time and let her rip all night. It will be in the 70s in the morning.

Just noticed how you have your settings and saw the difference on mine…I keep the room temp all the way to the right, it helps with temperature consistency and I’ve never adjusted it.

Just a note, I woke up and it was idling away, even though it was on stove temp. Note sure why? It was set on 1 when I went to bed on stove temp and temps had drop to 72 from 74 same outside temps. when I hooked up the external sensor it woke right up and started pouring out heat. I've changed to the new one and monitoring. I have it set on 75 vs 80 which was the room temp. It's now barely running, looks like it will go out. More later.

Are you sayig the room temp probe wasn't hooked up? If so, I've found that it confuses the stove so it just idles.

I got down to burning embers, no flame so I turned it up to 77 and it started dumping pellets. I'm afraid it was going out. Temp was 78 on the thermometer. I had it set at 75. it's now pouring pellets out and heating up again. So the sensor works just curious why it's really dumping out the pellets. You'd think it would dump out small amounts.

Attached is the manual for earlier stoves, which has a better explaination of what "constant burn" mode (what is now called stove temp) is. Just do a search in the document for "constant".

Can I change from stove mode to room mode without stopping and restarting? And any ideal what the idle temp is, I'm going to try it later once it warms up enough. I believe I got it working last night. Also if I'm right the feed rate controls the temp on it.

I had 2 hooked up. Both worked as when I unhooked them the status light started blinking. I know how it works, I've been running it for 2 years now. But thanks this is my second P61, it didn't have an ignitor, so it was the only mode I had. I've switched to idle mode temp set at 75, going to see if the temp control will turn it down. Fire was 233, external sensor 84. house temp 74. I switched without turning it off and it works fine.

If you turn the dial very fast the igniter night not come on again. If the fire is going hot that will help. You can't control the idle temp in room mode. It just wants to keep the fire going. The stove will go down to 250 F to 275F with the fan off until more heat is needed. This is great in the winter when you always need some heat. Rate does not change the temperature, just how much it can feed all at once. The control board can do what it needs within a certain range. I always turn my pots up and down each time I started it so the wiper on the pot gets moved to another position. Another thing to remember is that you don't have total control over the room blower. The stove controls it. The only thing you can control for sure is the speed. You can play with the switch too, that can make a difference it how it works eg. In stove mode with the switch down, it may shut off below a certain heat setting.

It's doing something, I'm down to 2 and have managed to keep all the inside temps the same, despite the outside temps going up 10f. I'm trying to avoid using the Quadrafire as much as possible, although forecast is calling for 59f here today. 47f now up from 33f.
