If I read your post correctly, you set heat and blower to 1-1? If so, what you have in your picture is exaclty what I'd expect. The thermostat, even if working properly when calling for heat, you've maxed the stove out at 1-1. You won't get anymore out of the stove.

Before I turned it down I had it at 5.4.1 6.9 and I don’t know if it made a difference or put it up and down
 
My thermostat is not calling for heat I have it set to 6.4.1 7.7 don’t the flame look right?

Also what is the feed rate?

It is so hard to tell from pictures. The best way to tell is to test both sides of the J18 block pull wires that go to thermostat and test both sides of block for power only on side should have power.

If you want to do it by fire size set stove to heat 1 blower 7 and 6.4.1 wait 20 minutes look at size of fire. Make sure thermostat is NOT calling for heat, change only the heat setting to 7 wait 20 minutes fire should be same size it was on heat 1 (if it is larger it still is not working on H/L). If fire stays small, now turn thermostat up so it calls for heat (80 degrees should do), wait 20 minutes sometime in that 20 minutes the fire should get larger, stove is then working on H/L.

Last night I had it on 6.4.1 7.7 it used about a half a bag of pallets. And it was 75 in the house. I tried putting the heat on 1 this morning and stay high.
 
Did you try as ARC suggested? It is hard to keep track of all the changes you've tried. Start back with what ARC mentioned 2 posts ago and report back.

If you've set it for level 1 on the heat range, that will be your flame size, regardless if the thermostat is calling for heat or not.

If stove/fire does not go to 1 with thermostat off, or wires unhooked it is not the thermostat problem. You have to put stove into high low mode. Are you holding buttons long enough? Also unhook thermostat wires from board with no wires and no jumper stove fire should be on one. Listen to ericofmaine he has more knowledge of this stove then I.

I am just starting up my stove for the season and I tried putting it into HL mode and I don't know if it didn't but now the blower speed does not display and you cannot control it

It is a 2012 model. What is the best setting for it on off mode stove
Settings are hard to suggest, each stove, venting, location all effect the trim. 6.4.1 being the factory settings seems a good place to start and it appears they work well for you. If running stove in 1 or2 heat settings only 4.6.1 seems to work better.
 
So your back to where you were to begin with stove will only work On/Off and no High/Low. Your control board must be one of the old ones with no High/Low programing. Not going to be able to install a thermostat.

I put it on 4.4.1 7.9 last night and it's 51 outside and 76 inside and used about 1/3 hopper in 12 hours

I do not have same stove but at 51 degrees outside if I have my stove on 1.1 I have to open windows or my house to would be 76+. I would say if you were on 1.7 and you only used 1/3 of hopper in 12 hours then 76 degrees in house is impressive and just about right.
