ok... that I understand and agree.....Stove temp /manual.... .what about stove temp/auto and room temp auto/manual? basically, the other 3 modes of operation in regards to running fan on high
Stove temp - 100% driven the the ESP (temperature probe in stove exhaust flow). Temp dial corresponds to a fixed ESP temperature. For simplicity, let's assume a setting of 3 = 300 degrees ESP temp. The stove will ramp feed up/down to always be as close to 300 degrees as possible. In stove temp the stove doesn't care what the room temp is, only the ESP temp. The room might be 60 or 90 degrees doesn't matter, all it cares about is maintaining an ESP temp of 300.The stove will not shut off in stove temp regardless of whether the igniter switch is set to auto or manual. Stove temp, switch to manual - I call this fireplace mode. Distribution fan will not turn on unless the temp knob is set to 5 or higher. This is designed to give a nice fire, but not a ton of heat in the room. Most goes up the chimney. Stove temp, switch to auto - distribution fan operates normally to push heat into the room, regardless of stove or room temperature. There is a caveat to this, if you have your room temp set to 1 (very low) then the distribution blower might shut off because the ESP temperature is below the lowest setting allowed for the distribution blower to run.
Room Temp - The stove is 100% driven by the room temp sensor. The stove will automatically adjust feed and ESP temp to achieve the room temp set point. Once the set point is reached, the stove will slowly throttle up/down to maintain temperature. If it's 20 degrees outside, your heat load is high and the stove will feed more pellets to get the ESP temp hot enough to maintain room temperature set point. If it's 60 degrees outside, the stove will feed as little as possible and keep as low an ESP temp as possible to maintain room temperature. Igniter switch to manual, stove will go into maintenance burn in between calls for heat - prevents igniter cycling, might use a few more pellets in this mode...maybe... Igniter switch to auto, stove will initiate the shut down process in between calls for heat - igniter could cycle several times per day, depends on set point and heat load. If there is a call for heat during the shutdown process, the stove will start feeding pellets provided that the ESP temperature didn't go below the low limit. So, on really cold days, the stove might not shut off, even if it's on auto.
The key to getting room temp to work is placement or "calibration" of the room temp sensor. This is a tricky subject due to the sheer number of variables that can contribute to success or lack there of. Ideally, you want the tip of the probe in an area that is not subject to drafts, direct sun or areas that could lead to heat soak from the stove or areas that make it tough to calibrate like basement concrete floors. Ideally, you want the probe on an inside wall (no drafts), away from concrete and fairly far from the stove, even if you need to extend the wire. If the probe is where you are, then the stove can work to keep an even temp that works for you. If your set on having the dial temp correspond with the room temp, you will need to experiment for a while until you find the most reliable place for the probe to stay.
Alternatively, you can place the probe in a "stable" location and simply adjust the temp knob to achieve the most comfortable room temperature. Maybe 78 on the temp knob gives you a steady 72 degrees, no worries, just keep in mind that the probe reads 6 degrees high and do the simple math if you feel like adjusting the temp.
That was taken for the forum here.
In stove temp auto, the stove is just keeping an ESP temp so if you have it on low its not pumping out much heat, turn the fans to high (while keeping the same temp setting) then it will be pumping out heat therefore have to burn more fuel to maintain that set ESP temp.
Room temp is far more variable and without seeing the programming I can't give you a definite answer. However the fans are there for a reason.... I would keep them as high as you can tolerate as this is getting heat out the stove faster. In my eyes this will always be more fuel efficient.
