SENSOR INSTALLATION
TEMPERATURE SENSOR ASSEMBLY
For installation of temperature sensor in Hot Liquor Tanks and boil kettles , a ½”inch hole is required. Temperature sensors can be installed in the existing
BrewMometer™ hole in Blichmann Engineering BoilerMaker™ kettles. Install temperature sensor and bulkhead as shown in Figure 1.
For RIMS mash tuns, install the temperature sensor directly in the wort recirculation path immediately after the heat source (see Figure 1). Brewers using
the RIMS Rocket™ should reference the RIMS Rocket™ Owner’s Manual for detail instructions on installing the temperature sensor.
IMPORTANT: Installing the temperature sensor directly in the mash tun will result in instability and severe overshooting of mash temperature. Always
install the temperature sensor in the wort recirculation path as close to the heat source as possible as shown in Figure 2.
TIP: Use the optional temperature sensor fitting, part number BE-000268-00, for inline sensor installation as shown in Figure 3.
CAUTION:
•Do not pull sensor by cord, pull by stainless sheath only.
•Do not remove sensor when kettle is full of liquid without optional thermowell.
OPTIONAL THERMOWELL:
The optional Thermowell (BE-001500-00) is available to purchase to allow sensor removal in full kettles.

for recirculation are open.Then, set the pump button to on (green). NOTE: As a safety feature,
the controller will automatically turn off the heater after 6 hours if the SET point has not been changed.
SET PT ALARM – This audible alarm will alert the user that the set point is close to being reached.
Values from 0-9˚can be selected. Choose OFF to disable this alarm. Default value is 5˚.
OUT OF RANGE – This setting will alert the user that the actual temperature is outside

AUDIBLE ALARMS – Used to enable or disable ALL audible alarms. Color indicators will still function. Value is ON/OFF.
UNITS – Changes all temperature Units between C and F.
CALIBRATE - The sensor supplied with this product is extremely precise and accurate and does not require calibration. However, calibrate can be used for
sensor to sensor variation, if the user so desires to fine tune this reading, or simply match to another sensor. For example, if CALIBRATE is set to +0.7, the
sensor values will be increased by 0.7˚.
In the BASIC SETTINGS screen press the ADV button to navigate to the advanced settings screen.
The advanced settings are intended to enrich the user experience for the ultimate in performance.The
default values will provide excellent control for most applications.
MASH HEAT RATE - This setting is used to compensate for the heating delay time between mash steps
when using the Mash Timer. Since each system will vary in how fast it can heat, the user will need to
experiment with their system to measure the approximate heating rate in degrees per minute. The
controller will add extra time to the rest to allow the mash to heat to the rest temperature before
activating the rest timer. During the ramp time the TIMER will alternate between RAMP and remaining
time. Default setting is 2˚per minute.
Measuring the Ramp Rate
To measure the approximate ramp rate of your system measure the time it takes to go through a typical ramp. Divide the change in degrees by
the ramp time in minutes. For example, if ramping from 145 F to 155F takes 5 minutes, the ramp rate is (155-145)/5=2 deg/min. Enter this value
in MASH HEAT RATE.
RIMS OFFSET - This offset is used for Recirculation Infusion Mash System (RIMS), Heat Exchanger Recirculation Mash System (HERMS), or the Blichmann
Engineering™BrewEasy™Kettle RIMS system. In these systems the temperature at the sensor will read an average of a few degrees higher than the
actual temperature in the mash due to heat losses. The RIMS offset increases the temperature of the mash to match the Actual Temperature displayed on
the BrewCommander™ .
Measuring the RIMS Offset
Ensure the RIMS OFFSET is set to 0.0. Next, calibrate your mash thermometer to match the BrewCommander™ sensor so that you can accurately
measure the temperature difference between the mash and the recirculation temperature. Calibration at your typical mash temperature is most
accurate. During a mash, allow the mash thermometer to reach a steady state temperature. This may take 30-45 minutes. Subtract the mash
thermometer temperature from the BrewCommander™ temperature. Enter this value into the RIMS OFFSET. From this point forward, the
brewer can enter the desired mash SET temperature without having to compensate for temperature losses.
BASIC SETTINGS
ADVANCED SETTINGS

BrewCommander™ © Blichmann Engineering, LLC 2019 10
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 - (intended for gas systems only) This value should always be set to 0.
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 6˚(+/- 3˚
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
5 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.
For the BrewCommander™ electric modular brewing system to function properly in a recirculation system (RIMS / HERMS), your brewing system must meet
some basic requirements. If your system is unable to meet these requirements please contact your RETAILER for guidance. We cannot guarantee the
performance of the product if these basic minimums are not met.
For RIMS brewers, your mashing system must be capable of continuously recirculating wort with a pump for the duration of the mash without sticking.
The flow rates in the chart below are minimum values.

IMPORTANT: Grain bed flow rates are highly dependent on
crush quality and mash tun geometry. Move to a coarser
crush if you are not able to achieve the above flow rates. It is
also recommended that you allow a 10 min dough-in prior to
turning on the pump. This allows air to purge from the grain
bed and for the grain to fully absorb the water.

General Operation
When using a RIMS Heater, such as the Blichmann Engineering RIMS Rocket™, the temperature readings taken in the RIMS Heater will be higher than vessel
temperature. This difference varies depending on the power supplied to the RIMS Heater and the rate of flow of the wort or hot liquor through it. When the
vessel is at a steady temperature this temperature difference is typically from 1˚to 4˚F due to normal heat losses in the system.When using the RIMS
Offset feature, the temperature displayed on the controller will always be the measured value from the temperature sensor minus the programmed RIMS
Offset value in the advanced settings.
Heating Strike Water
It is common to heat the strike water in the mash tun using the RIMS heater. However the rims offset for heating a mash is higher than that of heating strike
water. To compensate, use a set point 1-2 degrees below the desired strike water temperature. This can be fine tuned with experience using your system.
Mashing
The brew commander can compensate for losses in the system by using the RIMS OFFSET feature. The set point should be programmed to the desired mash
temperature. The above recommended Basic and Advanced settings are a good starting point, and can be adjusted with experience. Refer to the advanced
settings section for details.
TIP: If step mashing, decreasing your control band will help speed up the heating between steps, but larger temperature fluctuations will be experienced
in the RIMS Heater.

General Operation
It is important to be aware that when using a HERMS Coil during a mash the temperature readings taken in the HERMS kettle (typically the HLT) will be
higher than the actual temperature in the mash. This difference varies depending on rate of flow, whirlpooling in the HERMS vessel, and temperature
losses unique to the system. When using the RIMS Offset feature, the temperature displayed on the controller will always be the measured value from the
temperature sensor minus the programmed RIMS Offset value in the advanced settings.
Heating the Strike Water
A unique feature of HERMS systems is that there are many different ways to achieve the heating of strike water. These different methods have unique pros
and cons and varying equipment needs. Experimentation and practice with your particular system is the only way to truly fine tune strike water
temperature for your mash.
Method 1 is to recirculate the mash strike water through the HERMS coil while heating the HLT.
Method 2 is to heat the HLT (where the HERMS coil is located) to the desired temperature, while heating the strike water in your boil kettle with a second
controller. This method is faster due to using two heat sources.
Mashing
While mashing, the brewer must maintain a slightly higher temperature in the HLT than the desired mash temperature due to heat losses and inefficiency
of the heat exchanger. Whirlpooling in the hot liquor tank significantly increases the heat exchanger efficiency thereby reducing ramping times. For more
information about our Kettle Whirlpool Kit, visit https://www.blichmannengineering.com/whirlpool-kit.html.
The RIMS offset can be programmed to compensate for losses in the system. If whirlpooling in the HLT during the mash, the RIMS OFFSET should be
programmed to 3˚F. If not, this should be set to 5˚F. The SET point should be programmed to the desired mash temperature. With experience these
settings can be fine tuned.
For step mashing with a HERMS system, a mash heat rate of 1°F or lower is recommended over the default 2°F. This allows more ramping time between
steps to allow the slower heating rate of the HERMS system to reach the next mash step.
