Hey, all. Recently bought an Enviro Meridian after 14 years of a Mount Vernon AE. The description of the different modes is a bit unclear to me. Looking for the optimum mode setting for my situation: I run both my furnace and pellet stove at the same time on thermostats to reduce their fuel and wear (has worked great). I live at 7,200' and have a 1,400 sq ft 3 bedroom home . Can someone better explain how the High-Low and Auto-Off modes function? I still work 9-5 and would like to keep the house around 65 deg. or so when I'm gone... which of those two setting would be best for me? I'm glad to be rid of the Mount Vernon's excessive gadgetry, but am having a hard time learning how to fine-tune and best-use the Meridian. Thanks!

High/Low Using a Thermostat: Say Stat set at 70 
Temp drops below 70, the stat calls for heat. The stove will ramp up to high
When 70 has been reached, the stove will throttle back to low and maintain
a maintenance fire.
On/off Same as above, except the stove will shut down when the set Temp is reached
Then restart when heat is called for. The stove has to refire and heat up to reach the set temp.
If it were me, I would use the high/low yes it may use a few more pellets, but it is also still supplying
a little heat when in low . It also starts to give heat when the stat calls for heat much faster, and it is
a lot easier on the ignitor
Just my nickel's worth

Good luck on your Enviro- lots of us Enviro people here. The Meridian has been around a long time, a real workhorse. Love the cast version too (FS)! Good luck, John above is a real Enviro guy here on the forum, he and I try to watch out for our Enviro compadres. Stay warm, sounds like you got that covered though.
I definitely appreciate the feedback. My stove still seems jiggy, but the dealer/installer is a great guy and he's been back to help w/ the settings. I might have run into some bad pellets that screwed up my Quadrafire auger and eventual circuit board, and are now vexing my new stove. It'll run great for a day of football (like yesterday, w/ me watching it carefully) on high/low and through the night, but I came back today and it was out (I turned the t. stat down to 65). I tried starting it up again in High/low just now and had no luck; it seems that it's not dropping enough pellets. Related to that, the auger trim button doesn't seem to change anything at all. Yest. I gave it a cleaning, even though it's only been through two or three bags of pellets (and pipes were cleaned out three weeks ago at install). At the moment it's burning on manual. Air intake seems fine, but the back wall is pretty sooty and dark.
I did look up the cast iron Meridian (!). That thing looks like my old Mount Vernon; shoulda gone with that! I'm hoping the jiggines involves user error and my learning curve, but so far I haven't been able to be confident about this stove just yet.

Above is the Envrio Flame pattern at 7200 ft. You may need to increase the combustion air. On the restart, was the stove still fairly
warm? Envrios will not restart (igniter turn on )if the proof of fire switch is over 140. Are you useing a OAK ? How tight is your home ?
Auger trim
AUGER TRIM: Used to change feed rates on LOW ONLY for poorer quality fuels. Push the Auger Trimbutton until the number 1 and 5 lights appear on the Heat Level Indicator. This will increase the feed rate to four (4) seconds ON time Auger pulse. This is done only on LOW to allow the burning of poor quality fuels. Push the button until the number 1 and 4 lights appear, this will reduce the Auger Ontime to two (2) second. This setting is for high-grade fuel only. Push the button until just the number1 light is on, this is for a three (3) second on time (standard setting).
Try using the poor pellet 4sec on pulse

After just running about an hour on manual on the fourth heat setting light, the flame has been all over, climbing all the way to the top, looked healthy and spryy around 6-8", and is now has dyed completely... very frustrating. There was about an inch to an inch and a half of un-burned pellets in the pot. Also, the auger seems to get starved as a valley of pellets open up through the middle, leaving two piles up on each side. Those side walls don't seem to slippery... they almost feel tacky.
Is there a video or set of threads that describe the characteristics of each mode? I know it's a well-engineered stove, but so far this particular unit has been erratic.
