Timer Setting and Operation 

Note: to help prevent keypad damage, push keypad buttons only with finger or thumb; do not use 

fingernail, utensil, tool, pen, or other object. 

Circulation fans may be turned on or off by the switch at the top rear of the HFD (HFD 7 and HFDC).  

 

 

  

Normal Operation 

Pressing the 

I/O

 button turns the HFD on or off.  When controller is off, all lamps, heaters, displays, 

and indicators are off.  Front on/off button (HFDC only): press and hold for 5 seconds to turn the 
HFDC on or off.  

 
 

  

Timers 

Holding down the 

TIME

 button then pressing a 

Timer

 button turns off the timer. When a timer is off, 

pressing the 

Timer

 button once sets the countdown timer to the value preprogrammed into the 

controller. 

Pressing the 

Timer

 button again within three seconds (while the indicator next to the button is 

blinking) sets the timer to 30 minutes.  

Each successive press (within three seconds) adds 30 minutes to the time, up to 4 hours. 
At 4 hours, the next button press cycles the timer back to 30 minutes again.  
Once the timer is activated, the 

LED

 next to the shelf timer button stops blinking and stays on. 

The display then reverts to HFD internal air temperature.  
While a timer is on, pressing a timer button displays the remaining time for 4 seconds, then shelf 

actual temperature (not the setpoint) for 4 seconds, and then the display reverts to the internal 
ambient temperature display.  

At 15 minutes remaining time, the 

LED

 turns yellow. 

When no time remains, the 

LED

 turns red plus an audible alarm sounds.  Shelf heaters stay on.  

Pressing the timer button next to the blinking red 

LED

 clears the alarm and restarts the timer. 

 

Converting Temperature from °F to °C (or °C to °F) 

With controller power off, hold down the 

TIME

 button, then press and hold the 

I/O

 button until the 

display comes on.  The display shows the firmware revision (example 4.11).  

Press and release the 

TIME

 button to change from °F to °C (or °C to °F).
