6100 C codes (by jawquin)

Here are the C settings for firmware rev 5.04

C- 1 - Reset to defaults (hold Mode and Auger Delay buttons for 3 seconds to
reset all to defaults)
•
C- 2 - Fuel Lbs Per Hour HR 1 (0-8.0) - This is the fuel rate in pounds per hour
for a heat range setting of 1. The default is 2.0lbs.
•
C- 3 - Fuel Lbs Per Hour HR 9 (0-8.0) - This is the fuel rate in pounds per hour
for a heat range setting of 9. The default is 6.0lbs. The fuel rates used between
settings 1 and 9 are linearly interpolated between these two settings.
•
C- 4 - Agitator On Percentage HR 1 (0-50) - This is the Percent On time for the
Agitator for a setting of 1. The default is 25%.
•
C- 5 - Agitator On Percentage HR 9 (0-50) - This is the Percent On time for the
Agitator for a setting of 9. The default is 50%. The percent on time for the
Agitator used between settings 1 and 9 are linearly interpolated between these two
settings.
•
C- 6 - Draft Fan Level HR 1 (0-500) - This is the Draft fan output level for a draft
fan setting of 1. The default is 215/500.
•
C- 7 - Draft Fan Level HR 9 (0-500) - This is the Draft fan output level for a draft
fan setting of 9. The default is 225/500. See next parameter for disbursement.
•
C- 8 - Draft Fan Full On at Setting 9 (0-1) - If this parameter is set to 1, the setting
for C7 is used for a fan speed of 8, and a value of 500 is used for a fan speed of 9.
If the parameter is set to 0 (default), the setting for C7 is used for a fan speed of 9,
and all remaining fan speeds are set based on the interpolation between C6 and
C7.
•
C- 9 - Ramp Seconds for Increasing Level (0-300) - When the heat range setting
is adjusted, the control will ramp from the current setting to the target setting to
avoid abrupt changes in the outputs that could cause problems with the flame
quality. The Ramp Seconds value sets the amount of time to spend on each heat
range setting (1-9 pseudo ranges not 1-3 user ranges) as the current setting is
ramping toward the target. If the current setting is ramping down toward a lower
target, the ramp value is half this number. The default value is 90 seconds.
•
C-10 - Startup Minutes for Detecting Warm Furnace - (10-60) This is the amount
of time the control will wait for the furnace to reach the warm temperature (110
Degrees F) after the furnace has been started before shutting down and reporting
an Error condition Err3. The default is 30 minutes.
•
C-11 – Overtemp Setpoint (above ambient) - (0-300) This is the number of
degrees above ambient that the measured flue gas temperature can reach before an

overtemp condition exists. If the measured temperature is higher than ambient +
this setpoint, the control will stop augering fuel until the temperature returns to a
safe operating point. The default is 255 degrees above ambient.

•
C-12 – Cutback Setpoint (above ambient) - (0-280) This is the number of degrees
above ambient that the measured flue gas temperature can reach before a cutback
condition exists. If the measured temperature is higher than ambient + this
setpoint, the control enforces the PID temperature control algorithm. The default
is 220 degrees above ambient.
•
C-13 – Room Fan On Setpoint (above ambient) - (0-200) This is the number of
degrees above ambient that the measured flue gas temperature can reach before a
the flue controlled foom fan turns on. If the measured temperature is higher than
ambient + this setpoint, the control will turn on the flue controlled room fan. This
variable also serves to indicate to the control that the stove is warm. If the
measured temperature is higher than ambient + this setpoint, the stove is
considered warm and will not create an Er 3. Whether or not the stove is warm
also determines if the unit will recover from a power failure. If the stove is warm
when power is lost and cold when it returns, it will shutdown with an Er 4 error.
The default is 80 degrees above ambient.
•
C-14 – Cold Stove Setpoint (above ambient) - (0-100) This variable is used to
determine when the furnace is cold and ready to be shut down. If during the
shutdown sequence the measured temperature is less than this value + ambient,
the furnace will stop running the fans to cool it off. The default is 40 degrees
above ambient.
•
C-15 – Low Temp Vent Setpoint – (70-200) This variable is used to control the
vent controlled room fan. If the measured vent temperature is greater than the
Low Temp Vent Setpoint, the vent controlled room fan will turn on. If the
measured vent temperature is less than the Low Temp Vent Setpoint – 5, the vent
controlled room fan will turn off. The default for this setpoint is 115 degrees.
•
C-16 – High Temp Vent Setpoint – (70-250) This variable is used to limit the
maximum vent temperature. If the measured vent temperature is greater than the
High Temp Vent Setpoint, the furnace will reduce the heat range by 1. If the vent
temperature falls below the setpoint – 5, the heat range will ramp back to normal.
The default for this setpoint is 180 degrees (subject to change).
•
C-17 – Calculate Ambient – (0-1) If set to 1 (default), the ambient temperature
sensor and flue gas temperature are combined to calculate the ambient
temperature outside the furnace. If set to zero, the ambient temperature is
assumed to be 70 degrees F.
•
C-18 – Proportional PID Constant – (0-1000) Proportional constant for cutback
temperature control. Default is 80.
•
C-19 – Differential PID Constant – (0-1000) Differential constant for cutback
temperature control. Default is 100.
•
C-20 – Integral PID Constant – (0-1000) Integral constant for cutback
temperature control. Default is 50.
•
C-21 – Blast Cleanout Period – (0-1800) Number of seconds between blast
cleanout periods. The default is 900 seconds = 15 minutes.

•
C22 – Blast Cleanout Duration – (0-300) Number of seconds to perform the blast
cleanout function. The default is 60 seconds.



Re-lubricating the Agitator gearbox by SidecarFlip (photos by me.)

1. Press the off button on the touch pad and allow the stove to shutdown. Open the door and remove the hairpin that connects the agitator and the drive input. Then unplug the appliance.

2. Remove the control board side panel by removing the self tapping screws (2 on top and 2 on the backside). Remove the panel being careful with the control board harness. Then, remove the 2 spade terminals from the upper snap disk and the 2 spade terminals from the agitator motor. With the same socket you removed the side panel with, remove the 2 self tapping screws that attach the crossbar that keeps the agitator motor in place and remove the crossbar. Then remove the agitator motor by pulling straight out.

3. Secure the motor gearbox assembly in a vise, clamping lightly on the black motor laminations with the output (agitator shaft) pointing up. The diecast aluminum gearbox housing will be completely in the open, above the motor. Don't clamp it too tight, just enough to secure it.

4. Take a small punch and drive the roll pin from the shaft coupler, remove the coupler and set aside the pin and the coupler.

5. Take a Torx bit and remove the 6 black colored self tapping screws visible in each corner and in the middle and set aside.

6. Carefully separate the upper half of the case from the lower half, pulling upward while wiggling it. Keep your thumb on the output shaft end and apply a little pressure to keep the gear set in the lower case. When the upper case comes free, there will be a loose flat washer and 2 small lengths of colored plastic spacers. The spacers go on each axle near the motor end of the gearbox (they only fit on their respective axles) and the flat washer is the thrust washer for the output shaft.

All your grease will be in the lower end of the housing. There is no need to remove the gear sets, just remove as much of the old stuff as possible from the case and the half you removed.

7. You will need a 1/4"x28 Zerk (Alemite) right angle fitting, a 1/4"x28 tap, a No.3 drill and a No.60 drill.

8. Take the No.3 drill and drill a hole in the case that is attached to the motor (the one you have in the vise), about 1/2' from the bottom and tap it 1/4"x28. Carefully remove any chips that may have got on the inside of the case half. When I reference the hole, I mean drill and tap a hole 1/2" from the bottom edge of the case half you have held in the vise and 1/2" fro the bottom on the vertical side of the case half.

9. Thread the Zerk fitting in the threaded hole and tighten with the end pointing down.

10. Take the other case half and at the top (the top is above the output shaft hole), drill a hole with the No.60 drill for grease relief.

11. Re-assemble the case haves. Put a smear of grease on the output shaft before you slide the case haves together. Re-install the 6 self tapping Torx screws, attach the coupler and drive in the roll pin. Remove the assembly from the vise and fill the case with grease until it comes out the relief hole. Wipe off the excess grease and reinstall the gearbox motor assembly in reverse order. I put a little extra grease on the coupler where it rides in the bronze bush in the stove wall.

Every spring when you shut the unit sown and clean it, just give the Zerk a few strokes of the grease gun until clean grease appears from the weep hole and wipe the excess off. I used synthetic high temperature grease, but I suspect any good quality bearing grease will do nicely.

The auger gearbox assembly is the same so you can apply the same method to lubricate it as well. However, the auger isn't subjected to the heat factor like the agitator gearbox is, so lubrication should not be a concern.

This was VERY easy to do. I recomend EVERYONE do it.
Your motor/gearbox will last indefinitely.

Here are some pics.

Driving out the pin.



Opening the case.

Like the man said, hold your finger on the shaft when opening the case to keep the gears in place.
Thought there would be more grease than that, but it was in good condition for almost 3 years old.

Affordable Replacment Motors
If you compare the Fasco part numbers to the AES corn stove part numbers you will see they are the same.
USSC 6039 is almost identical to the AES countryside and magnum models and use most the same parts.

USSC sent me a new board last year to replace the one that went haywire. The new board they sent (v0.26) looks exactly the same as the 4 button v0.15, all the buttons are the same but the factory defaults are different. The Factory test works the same for trouble shooting, the Error codes I don't know if they are the same, except that the Error 2 running out of fuel is the same, I know first hand.
So here is the difference between the v0.15 and the v0.26 that I found.

HR9 default setting is 5pph not 6pph (pounds per hour)
DF low setting is 230 of 500 not 219 of 500.

In HR9 you can still run it up to 6.5 pph so that is the same.
The DF high setting still only goes up to 500 so that is also the same.

All the controls work the same as the v0.15 to change your settings, so the above manual is still the Bible for the v0.26 with just the couple of changes of factory settings (default settings) that I've posted.

Happy heating.

6300 and 6500 C Codes

These are similar to the 6100 and 6220 but some are different

16. Adjusting Operational Constants
To adjust the operation constants, press and hold the MODE and AUGER DELAY
buttons simultaneously for 3 seconds. The display will show "C- 1". Use the HEAT
RANGE UP or HEAT RANGE DOWN buttons to change the constant number (see the
list of values below). When the desired constant is displayed, press the ON button to
toggle between viewing and editing the value. While editing a parameter, use the AUX
UP and AUX DOWN buttons to adjust the value to the desired point, then press ON
again to return to the constant number list. Press the OFF button to exit the adjust
operational constants mode.

That was an amazingly long post. And though it was cool, in so far as I didn't know you could post something so long, the really best place for something like this is in the wiki. I can set you up with an account if you don't have one yet. Post it there. Then just link to it from the forum. The content can be broken up and made easier to get at. Wikis are great for stuff like this.

But what if the

Wiki Leaks?
