Ambient Temperature Display
To turn the ambient temperature display on or off: with the controller on, press and hold the Time
button and press the I/O button. (This feature is disabled in firmware revision 4.01).
Front Door

reads "OPEn". After closing the front door, the lights turn on, and the display reverts to internal
ambient temperature.
Heater Temperature Adjustment
Push the I/O button to turn the unit off. The lights inside the HFD will turn off.
With controller power off, hold down the Time button, then press and hold the I/O button until the
display comes on. The display will show the firmware revision.
Push either of the two buttons corresponding to the shelf that you wish to change the temperature.
Both lights on either side of the buttons will begin blinking.
Push and hold the button on the left to decrease the temperature (shown on the display).
Push and hold the button on the right to increase the temperature (shown on the display).
Repeat the procedure using the buttons that correspond to each of the six shelves (for HFD6 & 7), or
four shelves (HFDM).
Once the temperatures are adjusted for each of the separate zones, push the I/O button to lock in
the new temperature settings and to turn the HFD back on (the lights in the HFD will come on).
