Once Timer Y reaches zero, disable Manual Control to cease heating and initiate flush
water to begin chilling. Monitor Vessel 2 (Boil Kettle) temp to reach transfer
temperature.

Turn Pump 2 OFF, connect the tubing to the fermenter, and Turn Pump 2 ON to intiate
transfer.

Once done transferring (or running a clean cycle) disable all Device Elements prior to
powering off the UniFlex.
Firmware Updates
The UniFlex contains a micro-controller which runs BruControl specific firmware. This firmware
can be updated as new versions are published. New versions will add new functionality and/or
remedy bugs. Firmware and the installation tool can be downloaded from
brucontrol.com/download/firmware/
The firmware is installed via OTA (Over-the-Air), therefore the UniFlex needs to be connected
to the Wi-Fi network prior to updating. BruControl should be closed or disconnected from the
UniFlex interface prior to updating the firmware.
UniFlex Interface Wiring Map
, the application and firmware utilizes “ports” to identify which
micro-controller’s connections are made to the internal devices. The ports and connections for
the UniFlex, are as follows. Note: this is called an Interface Wiring Map.
