RIMS PROTECT
- If a RIMS heater is on, but no wort is flowing, the wort will continue to heat and may scorch. The RIMS PROTECT feature is used to prevent
this situation by automatically turning the RIMS heater off when the pump is turned off. If the user desires, the pump and heater can be manually turned
back on. When set to OFF, this implies the user is not using the controller in a RIMS system and the auto heater disable feature will not be enabled. This
feature is not needed for HERMS systems. The default setting is OFF.
IGNITION DELAY
- This value adjusts the power cycle to accommodate for gas systems that have a delay between power being supplied and the flame
igniting. This creates a minimum on time for the power supplied so that the burner always ignites when power is called for and gas is not allowed to be
wasted or to dangerously build up around the burner without igniting. The controller will never call for the burner to turn on for a length of time that less
that the ignition delay setting. This value is preset for a Blichmann Hellfire® burner. If a different burner is being used, set it in accordance with that particular
burner’s operation. The default is 6 Seconds.
Setting the “Ignition Delay”
Use a stopwatch to measure the time between the “heat” symbol being displayed on the temperature controller and the flame fully igniting on
the burner. Take this measured time and add 2-4 seconds to it as a minimum flame time. This will be your new Ignition Delay value. If this value is
7 seconds or greater, adjusting the cycle time to a higher value than the default 20 sec is recommended. A (Cycle Time) : (Ignition Delay) ratio of
3:1 or greater is recommended. For example, a 10 second ignition delay would require a minimum of a 30 second Cycle Time.
CONTROL BAND
- This value adjusts the range near the set point that the controller begins to cycle the power on and off. The default value is 8˚ (+/- 4˚
from the set point) and should not need to be adjusted. Increasing this value reduces overshoot when ramping to the set point, but also increases the time
to reach the setpoint. Decreasing this value decreases the time to reach the setpoint, but also increases overshoot.
CYCLE TIME
- This value determines how frequently the power is cycled on and off when the temperature is within the control band. The default value is
20 seconds.
SS OFFSET
(Steady State Offset) - Steady State is when the temperature of the kettle is no longer rising or falling but has leveled out to a steady
temperature. The steady state offset corrects a difference between the Actual Temperature and Set Temperature on the BrewCommander™. This setting
adds a small increase in power to fine tune the system. This is particularly helpful when brewing in cold environments.
FACTORY RESET
- This feature will reset all the settings from any altered state back to the original factory settings programmed into the controller. It will
give the user the option to select ELECTRIC defaults or GAS defaults. Please note that all mash and boil profiles will be erased during this reset.
WITHOUT SS OFFSET
The kettle’s thermometer has stabilized at 151˚F and will not get any hotter. The BrewCommander™ is set at 152˚F
After a 1˚F Steady State Offset was applied, the temperature of the kettle will now stabilize at the desired temperature.
