The message is a two-word message that will cycle through on the timer bar in addition to the product name at that pan location.

1. WARM | UP | XXXX – When turning on holding bin the warm up message will appear until heaters reach within 15°F set point. a. Cleared when within 15°F of the set point.

2. HTR | OFF | XXXX – Heater off message appears when both the upper and lower heaters are off. a. Cleared when heater is turned on.

3. HTR | LOW | XXXX – Heater low appears if the temperature falls 15°F below the set point. a. Cleared when temperature is back in range. If not cleared, would require a service technician to repair.

4. HTR | HIGH | XXXX – Heater high appears if the heater is above 285°F for 20 minutes. a. Cleared when temperature is back in range. If not cleared, would require a service technician to repair.

USB Update Procedure (all bins except the 3Hx4W)

1. First, un-plug Kitchen Minder, translator box, and any cable translation cables from the PHU. These devices will interfere with the timer bar boot loading process.

2. Place the update files on the USB flash drive in the main directory (Do not put them in a folder on the flash drive). There are five files that you will need to put on the drive. Two for the controller board, mainbin.hex and DHBFWBIN.TXT. Three for the timer bars, mainbar.hex, auxbar.hex an d DHBFWBAR.TXT.

3. Once all files are on USB drive, turn power off to bin and place the USB drive with the files into USB port on the front o f the bin.

4. While holding down crown button on front right side of the bin, above the power switch, turn the power to the bin on.

5. Keeping the crown button pressed, wait for the “BL” (boot load) message to appear on the screen. Release the button approx . 5 seconds after the “BL” message appears or once the USB stick light begins to flash.

6. Wait for the display to show: a. (blank while upgrading main bin firmware) e. BL00 (0 timer bars left to upgrade) b. BL00 (searching for timer bars to upgrade) f. BN02 (2 timer bars detected and done with programming) c. BL02 (2 timer bars left to upgrade) d. BL01 (1 timer bar left to upgrade)

7. You can check the version number on the timer bars by pressing the Prince Castle logo button and the down button on timer bar.

USB Update Procedure (3Hx4W Bin Only)

1. The 3x4 bin requires two sets of files for the update, 10 files total. You will have a set of 5 files for the lower board and 5 files for the upper board. You can use one USB flash drive; however you can only have one set of 5 files on the USB drive at one time. The 5 files have the same names and therefore can not be kept on the USB drive at the same time.

2. Go through steps 1-7 as above placing the USB drive in the USB port labeled 1 on the front of the holding bin. When the bin i s done updating, place the second set of files on the USB drive.

3. Once all files are on the USB drive, turn the power off to the bin and place the USB drive with the files into the USB por t labeled 2 on the front of the bin.

4. While holding down crown button on front right side of the bin, above the power switch, turn the power to the bin on.

5. Keeping the crown button pressed, wait for the “BL” message, “BLnU” message, and the BL00 message (THIS WILL TAKE APPROX. 15 SECONDS) to appear on screen, then release the crown button.

6. Observe the top row of timer bars a. The top row will show dashed lines (indicating that it has entered the boot loader). b. The top row will show Prince Castle boot up, before going back into dashed lines display (boot loader for second time). c. The top row will go again to the Prince Castle boot-up and back to the dashes a third and final time. d. The Prince Castle boot-up will show again and the update is done.

7. You can check the version number on the timer bars (top and bottom) by pressing the Prince Castle logo button and the down button on timer bar.
