Feature Details

BrewWISE Smart Funnel

This Bunn coffee maker features BrewWISE technology to transfer your brewing and grinding settings across different Bunn machines. The ThermoFresh’s splash-proof coffee filter holder, called the Smart Funnel, contains a microchip that stores your brewing preferences from one BrewWISE component to another. For example, insert the Smart Funnel into the Multi-Hopper Grinder and Storage System and adjust your grind volume, then transfer the funnel to the ThermoFresh brewer. It will automatically read and adjust the coffee recipe to brew the perfect batch of coffee.

Programming Options

This Bunn coffee maker features 10 different buttons to give you a number of programming options, all of which are guided by the easy-to-read display screen. The ThermoFresh can be programmed to brew ½, 1 or 1½ gallons per batch, and the brewing temperature can be adjusted from 185-205º Fahrenheit. You can also program the strength of each batch and save your setting under a coffee recipe of your choosing, and you even have the power to fine-tune the way each batch is brewed with adjustable pulse brew and bypass percentage settings.

Advanced Settings and Diagnostics

The ThermoFresh has a wide range of safety features to maintain productivity, such as flow calibration, refill sensitivity and a funnel lockout to prevent operation unless the Smart Funnel is positioned correctly. More advanced safety and troubleshooting features are available under the “service tools” programming menu, where you can test switches or troubleshoot the brew valve, heating element and the funnel sensor coil’s frequency. The ThermoFresh provides plenty of options for both brewing and servicing, so users have the freedom to make as many adjustments as they’re comfortable with, plus it can be reset to its original configuration at any time by accessing the “factory defaults” programming menu.

Add-ons and Upgrades

  • ThermoFresh Server
    • Capable of storing up to 1.5 gallons of coffee, Bunn's vacuum-sealed, thermal server can keep coffee hot for hours.
  • Multi-Hopper Grinder and Storage System
    • Part of the BrewWISE product line, this matching grinding unit features a compatible Smart Funnel to turn the ThermoFresh into a one-stop coffee station.


Daily Maintenance

  • It is recommended that you use clean water to rinse out the thermal server and Smart Funnel at the end of each day. In addition, you should use clean water to flush out the coffee spout at the base of the thermal server.
  • To clean the exterior surfaces of the ThermoFresh brewer, use a damp cloth rinsed in any mild, nonabrasive liquid detergent.

Periodic Maintenance

  • Remove and clean the sprayhead weekly to maintain consistent water flow. Cleaning the sprayhead is a very simple process that requires no tools and can bce done in about 10 minutes. Begin by simply removing the seal and then clean out each hole, as well as the sprayhead fitting.
  • After replacing the sprayhead, the ThermoFresh may need to be recalibrated, which can be accessed through the programming menu. Recalibration will allow you to accurately adjust the sprayhead’s flow rate and can be done by following a few easy steps in the product manual.
