2. The Auger Feed button will allow the user to manually auger fuel into the burn pot on start
up when needed. This is particularly helpful in priming the Auger Tube when it is empty (After
the hopper has run out of pellets).
Do not tamper with the Auger Feed button to override the
automated feed system. This may cause the unit to Overheat.
To adjust the Feed-rates:
Hold the Auger Feed Button down and press the Heat Level High/Low button and this will
change the ON Time up or down .25 seconds from the factory setting. Watch the LED lights
to see the setting is on (it will flash the new setting). This new setting will stay in memory
from this point on.
3. The On/Off button not only turns the Stove On and Off, it also resets the board if one of the
sensors has detected a problem and the board is flashing a Diagnostic code.
4. The Draft Trim button allows for adjusting the Exhaust (Combustion) fan voltages up or
down providing for fine-tuning of the combustion air. The LED light bar indicates the level of
adjustment and the factory setting is the center LED light. This allows for 2 adjustments up and 2
adjustments down. (See point 9 on page 45)
To adjust the Combustion Fan voltages: Hold the Auger Feed button down and press
the Draft Trim High/Low button and this will change the fan voltage approximately 2.5
volts up or down from the factory setting. Watch the LED lights to see the setting is on (it
will flash the new setting). This new setting will stay in memory from this point on.
5. The Thermostat Slide switch allows the stove to be run in 3 different Modes:
a.
Manual Mode
. The Control Board controls all functions of the Prescott EXP and EXL.
b.
T-Stat Mode
.
The Stove is Fully-Automatic in the T-Stat Mode.
(T-Stat requires the stove
be turned on at the control board the first time).
The unit is hooked to a Thermostat and
when calling for heat the unit will advance to the Heat level set at the Control board.
Once the Heat demand has been met, the Stove will immediately shut down. Use this
setting when heating a small area or when Temperatures are Moderate.
c.
SmartStat Mode
. The unit is hooked to a Thermostat and when calling for heat the stove
will advance to the Heat level set at the Control board. Once the Heat demand has been
met the stove will drop to the #1 Heat Level setting
and pilot for one hour
. If the
Thermostat does not call for heat during that hour the unit shuts off and
re-lights itself
the next time the Thermostat calls for heat
. This setting is best used during early Fall or
late Spring, when constant heat is not needed.
6.
Cleaning Cycle.
The Prescott EXP and EXL only use Programs 3 & 4. These 2 programs
have a Cleaning Cycle built into them that allows
the unit to drop to the #1 level for 5 minutes on
timed intervals. During the cleaning cycle the Combustion Fan will run at line voltage to blow
excess ash from the burn pot.
The ON/OFF light blinks (slowly) and the control board is
locked out during this cycle
.
Pre-Lighting Instructions:
The Control Board has 4 separate programs. Two of the
programs are for the Auburn (Programs 1 & 2) and two of the programs are for the Prescott EXP
