Thermostat Function - St. Croix SCR Installation & Operation Manual

1. The Heat Level button will advance the setting up and down between level 1 and 5. It
will also be used in the Fine Tuning process of the feed rates if needed. (See point 4 b.
below)
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). This button is also used to make small
adjustments to the combustion air and the feed rates as part of the Fine Tuning process
of the control board. (See point 4 a. below)
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 lights indicate the
level of adjustment and the factory setting is the center LED light. This gives 2
adjustments up and 2 adjustments down. (See points 8 & 9 on page 61)
a. 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.
b. 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.
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 Stove.
b. T-Stat Mode. The Stove 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.
The Stove never shuts off and provides constant heat. Stove must be turned
ON/OFF at the control board.
c.
SmartStat Mode. The Stove 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 Stove
shuts off and re-lights itself the next time the Thermostat calls for heat. This
setting is the recommended setting if a thermostat is used. The stove is Fully-
Automatic.
