power draft blower will be full on, above 225 the power draft blower will be full off and
at 212.5 the power draft blower will cycle 50% of the time. The default value of 25
degrees will work well with most pits. If you notice that the pit temperature is oscillating
up and down more than 5 to 10 degrees and never settles out, the proportional band can
be made larger. Making the proportional band smaller will make the pit reach setpoint
faster, but will also increase the overshoot on startup. Each time you adjust the
proportional band, expect that you will also need to adjust the offset to make the pit
setpoint and actual temperature agree.
Cycle Time – This value is the time (in seconds) between power draft fan pulses. The
default value of 6 seconds will work well with most pits. The cycle time should be
lowered only if the pit temperature falls between power draft fan pulses.
Ramp Offset – When the ramp mode is turned on, the pit will be ramped down to the
meat setpoint + the ramp offset when the meat temperature = the meat setpoint. The
default value of 30 degrees will work well for most cuts of meat. Say your pit setpoint
was 275 and your meat setpoint is 180. The pit will be ramped down to 210 (180+30) as
you meat temperature climbs to 180. We determined the 30 degrees based on the amount
of evaporative heat loss in an average piece of meat. If you make this lower the meat
setpoint may never be achieved at the end of the ramp cycle due to the amount of
evaporative heat loss. If you make this higher the meat setpoint may be slightly exceeded
at the end of the ramp cycle.
