Regency gf55 feed rate questions

[Mregency]

I have a few questions about the stove that isn’t in the manual so figured I’d try here. Running the regency stove on a thermostat, does the feed rate matter? I’m just trying to run the stove on the lowest possible seating to heat my basement instead of using the electrical heat while using the least amount of pellets. The default setting for feed rate is setting 4 out of 5. I know that every rate is a 1/4 second difference so I’m assuming it doesn’t really save much by changing it. I’m just unsure if it’s better to run the stove on heat 1 and feed 1 without the thermostat or use the thermostat and try and figure out if the feed rate and heat settings even matter on that mode. Any help would be appreciated. I know it might sound a little confusing but maybe someone on here has that stove as well. Thanks
