Sorry for the late reply no power last night and just finished snow blowing 18 inches fun in the north country.
special settings you would have to use to use a thermostat
No special settings pull jumper and hook up external thermostat.
from PR-1 to PR-5) is that the same as HR1 - HR5
Yes same as HR (Heat Range) the P means you are in Pellet burning mode you can also burn corn in a 6100 and you would change from Pellet burning mode to Corn burning mode then it would say CR instead of PR.
jumper back in tonight to see if auto mode
can you run the pellet furnace on auto mode with the thermostat plugged in? it may be that most of the heat is being pushed out the exhaust since it is running at 100% all the time on manual.
Jumper has nothing to do with mode it only controls whether you are using external thermostat or not. You are indeed pushing some of heat out the vent. Manual mode only controls the draft/exhaust fan in manual mode the fan is running at 500 and you control draft using the damper in Auto (Automatic) mode the stove controls the draft fan at your highest heat setting PR5 the draft fan only runs at 225 so you are running more then double the manufactures preset setting. If you want to use auto mode you can adjust the C codes C6 and C7. The way to do this is in auto mode set your stove to PR1 make sure stove can stay running if not enough draft raise the draft setting using C6 default is 215 if to much draft lower the 215. Wait 15-20 minutes after any change to see effect. After you get stove to run on PR1 Set it to PR5 then use C7 to raise or lower draft fan default is 225 the few furnace I have worked on all had to raise the upper end draft to get it to run correctly increase it 10 at a time and wait the 15-20 minutes before increasing it again. After you get both the PR1 and the PR5 draft setting set right PR2,3,4 are set Proportionally by the stoves control board. It takes some patience and time but you can fine tune the fire so it will run in Auto mode on the thermostat. Don't worry that C codes state heat range goes from 1-9 some of the first generation 6100 went from 1-3 the some 1-5 and the newest board goes from 1-9. Default settings are still the same as stated. I thinkJeremy6500
even lowered his PR1 feed rate so it ran more like a pilot light. If he jumps in he could give you instructions on how the dialed in his U S Stove 6500 the big sister to the 6100.
6100 C Codes
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
values. While editing a parameter use the AUX UP and AUX DOWN buttons to adjust the value to the
desired point, then press the ON Button again to return to the constant number list. Press the OFF
button to exit the adjust operational constants mode.
C-1- Reset to defaults -hold MODE and AUGER DELAY buttons for 3 seconds to reset all to
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 5(0-8.0) – This is the fuel rate in pounds per hour for a heat
range setting of 5. 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 setting 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.
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. See next Parameter for disbursement.
C-8- Draft Fan Full On at Setting 9 (0-1) – If the parameter is set to 1, the setting for C-7 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 C-7 is used for a fan speed of 9, and all remaining fan
speeds are set based on the interpolation between C-6 and C-7.
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 set 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 Detection Warm Furnace-(10-60)- This is the amount of time the
control will wait for the furnace to reach the warm temperature (110°F) after the furnace
has been started before shutting down and reporting an error condition Err3. The default is
C-11- Over temp 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
exist. If the measured temperature is high than ambient+this setpoint, the control will stop
auguring fuel until the temperature returns to a safe operation point. The default is 255°F
C-12- Cutback setpoint (above ambient)-(0-280) - This is the number of degrees above
ambient that is 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 the flue controlled
fan turns on. If the measured temperature is higher than ambient + this setpoint, the control
will turn on the flue controlled ran 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 and ER3. Whether or not the stove is warm
also determines if the unit will recover from a power failure. If 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 shut down with an ER4. The default is 80°F above
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°F.
C-16- High Temp Vent Setpoint - (70-200) – This variable is used to limit the maximum vent
temperature. If the measured vent temperature is greater than the maximum vent
temperature. If the measured vent temperature is greater 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°F.
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 (0), the ambient temperature is assumed to be 70°F.
C-18- Proportional PID Constant-(0-1000) - Proportional constant for cutback Temperature
Control. Default is 100.
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.
C-22- Blast Cleanout Duration- (0-300) - Number of seconds to perform the blast cleanout
function. The default is 60 seconds.
