where is your room probe? (tip of probe)
 
is the tip in contact with anything ? Like the wall, a piece of furniture, etc.
 
If it was in contact with something solid, it tends to read the temp of that object. The object will have a more stable temp than the air. When the stove reads a stable temp that is equall to or higher than the temp it is set for, it shuts down.
Try moving the probe to another place, just to see if it makes a change. If that has no effect, you may have a bad room probe. It also could be a bad ESP or even a bad circuit board. I would try room probe first as it is the cheapest of the three ($10-$15).

Also, turn off the caps lock on your keyboard, when you type in all capitals, it is like SHOUTING on the forum!
 
ok, that's an easy one.
The way a Harman works in room temp is this:
As the room temperature rises and gets closer to the temp you have set the stove for, the stove's output will slowly decrease. If the room temp starts to fall, the stove's output will increase. The only way the stove will shutdown completely is if the temp in the room remains stable or increases without the stove's input. You will know the stove is in "shutdown" because the "status" light will go off.
In shutdown the stove will still feed at steadily a decreasing rate until it gets to a very low flame, then it will stop feeding an eventually go out.
 
From my experience, admittedly limited, your stove will only shut down if there is no reason for it to run. Your stove will throttle back as it approaches the set temperature. It is trying to maintain the exact temperature you have set. It will vary it"s heat output to maintain precise temperature in the room. Once the set temperature is reached, it will burn at minimum, and even turn the air circulating fan off trying to maintain the set temperature. If there is a need for heat, it will never get to the point where it will turn off like other stoves that run in thermostat on-off mode. If however, the temperature keeps increasing even at it's minimum output, it will turn itself off. I think this happens about 3* above the set temperature. Once the temperature in the room drops much below the set temperature, it will start itself back up. That is how it works in auto. In manual, it controls temperature the same way. The only difference is it will not shut down, even if it slow cooks you! This would be similar to a pellet stove running in hi-low mode.

IF I USE THE ROOM TEMP MODE ON MY P68 WILL THE STOVE TOTALLY SHUT DOWN WHEN IT REACHES TEMP.

this is totally normal IF AND ONLY IF the igniter is in the AUTO NOT MANUAL IGNITER mode..its the little toggle switch above the fan speed...switch it to manual and the stove will just idle down to a small fire with the distribution fan turned off till it needs to raise the temp again...this way the stove ALWAYS has hot pellets and won't need to reignite cold ones..yes it uses some more pellets but you will not notice that much of a difference in runtimes..hope this helps

here is what the manual states
In the Room Temperature Mode you can select either Auto or Manual modes for the igniter using the igniter toggle switch. When the toggle switch is in the Auto position the igniter located inside the burn pot is ready to automatically light the fire when required. When the toggle switch set to the Manual position the stove can be lit manually with either a gel or a wax type fire starter. (see lighting instructions on page 17.) With the igniter toggle switch set in the Manual position the stove will automatically adjust heat output, but the stove will not automatically shut down if no heat is required. Instead it will go to its lowest setting and remain there.
 
I only use auto mode to light my stove. I don't like having the stove shutting on and off durring the day; also, I feel it will only prematurely shorten the life of my ignitor. I really don't think it uses too many more pellets. I love my stove.
 
More than likely you will only experience the shut down in the begining and the end of the season (when the temps rise during the day). My experience so far during the cold season is that my stove decreases output and goes into a low burn, then increases as needed to maintain the temperature. I don't think that my stove has gone into a complete shut down. I think that the stove will stay in a low burn state for up to one hour (if no heat output is required) before going into the shutdown mode.
 
I felt it was best to save on the lifetime of the ignitor and start in auto mode and then after the flame is well established, switch the ignitor toggle down to manual. As the other post states, the flame will go down to a low fire until needed. It will never go out, unless of course you forget to load the pellets. The ignitor will not be switched off an on automatically, granted you may use more pellets, but I don't think it will be that much. If we are in the full blown heating season, it will not idle for long anyway. Maybe in the beginning and end of season that would be a different case entirely when it is not as cold all day long. It's all in the manual, as crappy a manual as it is.
