I checked the connectors for the fuses
Did you check the soldering joints were the fuse holders connect to the board? What does the stove do in test mode?
To run this test the UNIT MUST BE COOLED OFF. Power up the unit by plugging in the power supply cord
to the back of the unit. Press the on button and the circuit board then press and hold the Off and Auger
Delay buttons simultaneously for 3 seconds. To advance through the test press the on key. If the Heat
Range Light is on during every test check Hopper Switch Wires.
1. Exhaust Fan Output Test- The display will show “drift”. The exhaust fan is turned on full then
reduced to a level just above the typical minimum pressure switch setting. The ON LED indicates
whether the pressure sensor is detected. If the pressure switch is not detected, the fan ramps to full
on for two seconds then returns to the previously established level if the pressure switch closes. If
the Draft Fan Fuse is not blown and the fuse detection circuit is functioning
, the Draft Fan LED will
be lit and the other three top row LEDs will be off.
2. Room Fan Output Test – The display will show “rfan”. The room fan is turned on full. If the Room
Fan Fuse is not blown and the fuse detection circuit is functioning, the Room Fan LED will be lit and
the other three top row LEDs will be off.
3. Igniter Output Test – The display will show “ignt”. The igniter motor is turned on full. If the Igniter
(AUX) Fuse is not blown and the fuse detection circuit is functioning, the AUX LED will lit and the
other three top row LEDs will be off.
4. Auger Output Test – The display will show “augr”. The auger motor is turned on full. If the auger
fuse is not blown and the fuse detection circuit is functioning, the Heat Range LED will be lit and the
other three top row LEDs will be off.
5. Hopper Switch Test – The display will show “hppr”. If the hopper switch is open (lid is open), the ON
LED will turn on otherwise, it will be off. If the hopper switch is wired in series with the auger, this
test is not valid, and the validation of the hopper switch should be done in the previous Auger
6. Thermostat Input Test – The display will show “stat”. If the thermostat input is closed, the ON LED
light will be on, otherwise it will be off.
7. Flue gas Thermistor Test – The display will show the fluegas temperature in degrees F. This should
read 54° F
8. AC Frequency Test - Displays the measured AC frequency in hertz followed by the letter “H”.
This should read 59, 60, or 61H
9. Watchdog Reset – The Watchdog timer is tested to ensure that the board can be reset. The message
Also you could try to turn off fuse error codes in the C codes C 17.
To adjust the operation constants, press the 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 vales 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
again to return to the constant number list. Press the OFF button to exit the operational constants
C1- Reset to defaults (hold Mode and Auger Delay buttons for 3 seconds to reset all to defaults).
C2- Fuel Lbs. per Hour HR 1 (0-5.0) – This is the fuel rate in pounds per hour for a heat range
setting of 1. The default is 1.75 lbs.
C3- Fuel lbs. per Hour HR 9 (0-5.0) – This is the fuel rate in pounds per hour for a heat range
setting of 5. The default is 4.5lbs. The fuel rates used between setting 1 and 5 are linearly
interpolated between these two settings.
C4- Draft Fan Level HR 1 (0-500) – This is the draft fan output level for a draft fan setting of 9.
The default is 150
C5- Draft Fan Level HR 9 (0-500) – This is the draft fan output level for a draft fan setting of 9.
The default is 350. See next parameter for disbursement.
C6- Monitor Hopper Switch (0-1) – If this parameter is set to 0 (default), the hopper switch input
is ignored. If it is set to 1, the hopper input is monitored, and if the hopper is opened, the auger
will stop. The delay LED will flash when the hopper is opened.
C7- Ramp Seconds for increasing level (0-300) – When the heat range setting is adjusted, 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.
C8- Startup Minutes for detecting Warm Stove – (10-60) this is the amount of time the control
will wait for the stove to reach the warm temperature (110 Degrees F) after the stove has been
started before shutting down and reporting an Error condition Err3. The default is 30minutes.
C9- Over temp Set point – (0-500) this is the temperature the flue gas can reach before an over
temp condition exists. If the measured temperature is higher than this set point, the control will
stop auguring fuel until the temperature returns to a safe operating point. The default is 445
C10- Cutback Set point – This is the temperature that the flue gas can reach before a cutback
condition exists. If the measured temperature is higher than this set point, the control ramps
down the heat range according to the auger ramp seconds value. The default is 430 degrees.
C11- Room fan on set point – (0-300) this is the temperature that the measured flue gas must
reach before the room fan turns on. This variable also serves to indicate to the control that the
stove is warm. If the measured temperature is higher than this set point, the stove is considered
warm and will not create an Er3. Whether or not the stove is warm also determines if the unit
will recover from a power failure. If the stove is warm when the power is lost and cold when it
returns, it will shut down with an Er4 error. The default is 130 degrees.
C12- Cold stove set point – (0-300) this variable is used to determine when the stove is cold and
ready to be shut down. If during the shutdown sequence the measured temperature is less than
this value, the stove will stop running the fans to cool it off. The default is 110 degrees.
C13- Room fan level HR 9 (0-500) – this is the output level applied to the room fan for a setting o
1. The default values is 300/500.
C14- Room fan level HR 9 (0-500) – This is the output level applied to the room fan for a setting
of 9. The default value is 500/500. The room fan output levels used between settings 1 and 9 are
linearly interpolated between these two settings.
C15- Auger load time (0-30) – This variable is used to control the length of time that the fuel is
augured into the burn pot during startup. The default is 6 minutes.
C16- Starter on time (0-30) – This variable is used to control the length of time that the igniter is
turned on during startup. The default is 8 minutes.
C17- Ignore fuse errors (0-1) – This variable can be used to ignore errors detected by open fuses.
By default, it is o (do not ignore the vacuum switch), but can be set to 1 for diagnostic of
emergency operation purpose.
C18- Ignore vacuum switch (0-1) – This variable can be used to ignore the vacuum switch. By
default it 0 (do not ignore the vacuum switch), but can be set to 1 for diagnostic or emergency
C19- Bump rate in pounds per hour (0-0.5) – The bump rate defines the rate of fuel to be
delivered when the unit is over temperature or in shutdown to prevent burn back, Since this
stove design isn’t conductive to burn back, the default setting is 0lbs. per hour, but can be
adjusted to a maximum of 0.5lbs per hour.
C20- Purge time (0-120) – The purge time defines how many seconds to run the auger to purge
it on power down or shutdown as the stove moves from a warm state to a cool state. It is
intended to push and partially heated pellets still in the auger tube out. By default, the auger
will run for 30 seconds, but can be set between 0 and 120.
C21- Enable serial communication (0-10 – By default, serial communication is not enabled (0).
Set this variable to 1 to enable communication.
