NO. don't use the FEED 10. that will just push the coals off the grate.
(I have switches on my stoker and combustion blowers). Typically unplug the feeder motor, turn everything thing on, you can unplug the combustion blower if you want, start your starter bag or however you start the fire, plug in the combustion blower to get it going good, throw a handful of coal on top of the fire once it gets going, then plug in the stoker motor, and let the COALTrol take over, just put the thermostat down a few degrees so it's close to the room temperature. then gradually turn it up as needed.
If you read all the posts about the Setback feature, DON'T use it or only change it a couple degrees. Its not like a gas/oil furnace that is almost instant heat. Coal Takes a lot of time to warm up and cool down. That will make is overshoot or under shoot and your FR will vary a lot and thats probalby why you see 99 on it. Once the temp. is satisifed (if it is) it should start to go down, but it take a long while for changes to be seen, maybe and hour or two after the setpoint reaches room temp.
Also, whats your feed screw set at? how many turns out? that will affect feed rate and response time.
