IMPORTANT:
It is recommended that before changing the above settings to read the descriptions in the basic and and advanced setting sections to fully
understand how these settings function.
General Operation
When using a direct fire RIMS, the temperature reading taken in the path of the flowing wort will read slightly higher than the vessel temperature. This
difference varies depending on the size of the flame and the rate of flow of the wort or hot liquor through the system. When the vessel is at a steady
temperature this temperature difference is around 1
˚
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. If using
the RIMS PROTECT feature, whenever the pump is cycled from ON to OFF, it will automatic extinguish the burner to prevent scorching.
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 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 system.

For the BrewCommander™ gas 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.

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.
