FIGURE 6: CONTROL BOARD FUNCTIONS
Country Flame’s control board provides reliable control of stove functions with minimal human intervention
required. This control technology provides flexibility in adapting to future changes and improvements in
technology. Finally, this control technology offers a simple interface between the operator and the product
being used.
Country Flame’s control board is sensitive to utility grid power variations. In the event a homeowner’s area
has difficulty with utility power fluctuations, Country Flame’s stove products can be interfaced to an
inexpensive battery back up system. The actual cost of a battery backup system will be fully dependent on
customer requirements. From random power “glitches” or short duration electrical power interruptions to
major power outages, the Country Flame stove can operate off battery or generator backup systems. Contact
Country Flame or one of its local authorized dealers to discuss the specifics of a single application.
In conclusion, Country Flame is striving to become a leader in the area of biomass control and product
technology. This leadership will provide direct benefits to Country Flame distributors, dealers, and our
customers. As always, Country Flame welcomes input on how to better meet the customer’s needs.
ON/OFF SWITCH
The ON/OFF Switch serves to turn the system on and off by holding the switch for
approximately 5 seconds. The ON/OFF Switch can also be used to initiate the
FUEL PRIME MODE by holding it for approximately 30 seconds. When in the
prime mode the Thermostat lights will sequentially light from top to bottom
simulating a “filling action” of the auger tube. In a fully automatic mode pellet
stove, the ON Function of the switch is ignored.
HEAT UP/ HEAT DOWN SWITCH
When these two switches are pressed during the STARTUP CYCLE only, they can
be used to turn the stir rod of the Harvester model. In all other pellet stoves these
switches only function as heat up and down switches.
DC POWER LIGHT
This is a 3-color light when AC power is applied. A red light indicates that the
Control Board has DC Power available but the system is off. A green light
indicates that the System is on. A yellow light indicates that the combustion air
should be cleaned. As Country Flame works to improve the sensor technology,
this yellow light will become more valuable to the service technician as well as the
homeowner.
HIGHWAY PATROL MODE
When all Control Panel lights are flashing on and off, this indicates that the
Product has an encountered an unknown state. Nothing more, nothing less. The
purpose of these flashing lights is to alert the home owner or the service technician
that the stove operation ended out of sequence, ran out of fuel, or encountered a
power interruption that the Control System could not recover from.
COOL DOWN MODE
In the Cool Down Mode, the Heat Setting lights will sequentially go out from top
to bottom, all relight and then sequentially go out from top to bottom. This cycle
will continue until such time that the Control Board senses the stove has properly
cooled down.
HEAT SETTING 1 THROUGH 5
Each heat setting, controlled by the stove Heat Up or Heat Down switch, is
provides as much combustion air and fuel as is required for that heat setting. Due
to the number of unique environmental variables as well as variations in pellet fuel
used in different regions, Country Flame cannot provide exact BTU ratings for
each heat setting except those that were established in Government Test Labs
under controlled conditions. At the same time, the rule of thumb is that each heat
setting on the Country Flame line of Biomass Product starts at one pound of fuel
per hour and increments to a top setting of five pounds of fuel per hour. Using a
BTU rating of from 4,000 to 10,000 BTU per pound of fuel, depending on the type
and moisture content of the fuel, an estimate of heat output can be made.
