Other Parts

Optional Parts

The items marked with an *asterisk above are optional. They are in the design to provide a means to monitor and trend one’s ambient temperature where the fermenter is placed, and/or the fermenting liquid’s temperature via a thermowell or insulated in contact with the fermenter. If one chooses not to use these, the firmware will automatically skip reporting these readings.
