Turbo Control

After lighting the fire, the ESP probe in the exhaust
senses when the temperature is high enough to start the
feed motor and distribution blower.
The feed motor will start and stop as needed to
maintain a fire relative to the dial setting of the feed rate.
Turbo Range
Turning the feed rate knob into the Turbo range
causes the feed rate to increase, providing extra heat
not available in the normal range. It also causes the dis-
tribution blower to go to full speed. This is because you
are asking for extra heat output; therefore, full blower
speed is required.
Blower Speed Adjustment
This knob adjusts the blower speed from "Low"
to "Hi" as desired. When the feed rate is turned into the
Turbo range, the blower automatically goes to high to
force maximum heat into the room. The blower speed
cannot be varied when in Turbo range.
When a thermostat is connected, the blower is con-
trolled by heating demands.
Thermostat ( optional )
When a thermostat is connected to the stove it
controls the heat output. When the thermostat calls for
heat, the feed rate and blower go to "max" just like in
Turbo range. When the thermostat is satisfied, the feed
rate and blower speed drop to the levels set on the di-
als.
OFF
When the Feed Rate dial is turned to the OFF
position the fire will slowly die and go out. When the
stove cools down enough, all motors will stop.
If the stove runs out of coal and cools down, the
control will shut down all but the combustion blower.
The control must be turned to OFF to stop the combus-
tion blower. Whenever the stove runs out of pellets, the
control must be turned to OFF and then back to the
desired setting to reset the control for start-up.
Test Mode
To use test mode, turn the feed rate to OFF and
then to Turbo. This will cause all the motors to run for
one minute or less in order to verify operation. If the test
does not last long enough, simply recycle test mode.
