PREHEAT: 

 
1.  The  controller  will  stay  in  preheat  mode  ("PHt")  for  the  entire  preheat  period  (preheat  time 

parameter) even though both heaters (top and bottom) have reached set points before the end 
of that period.  If the controller is inadvertently turned OFF and back ON, the preheat period can 
be  bypassed  by  a  3  second  press  of  the  down  arrow button only if both heaters are within the 
allowed differential temperature set points (preheat bypass temperature parameter). 

 
2.  After preheat, the controller goes into idle mode "---".  At this time, any timer can be started. 
 

HOLDING TIME CYCLES: 

 

1.  To start a cycle, press a timer start/stop button.  The display will show the holding time value in 

minutes  and  starts  the  countdown.    The  LED  bars  for  that  timer  channel  will  then  light  steady 
green. 

 
2.  When the timer reaches the pre-alert value, the display will then alternate between showing the 

remaining time and "drP" for DROP, the LED bars will start flashing and a beeping will start.  The 
user then has to acknowledge the pre-alert by a press of the timer start/stop button.  The display 
will then  flash  the  remaining  time  for  the  rest of the cycle, the LED bars will go back to steady 
and the beeping will stop. 

 

3.  When the timer reaches the "000" value, the display will flash "000", the LED bars will flash red 

and the beeping will start until the user acknowledges the end of the cycle by pressing the timer 
start/stop button.  The timer will then go back to idle mode "---", the led bars will turn OFF and 
the beeping will stop.   

 

4.  Any holding cycle can be cancel at any time by a 

U

3 second press

U

 of the timer start/stop button. 

 

5.  If  at  any  time  during  normal  operation, 

one  heater’s  temperature  is  falling  or  rising  out  of  the 

allowed differential from set point (ready mode differential parameter), the displays will alternate 
between current mode and "LO" or "HI" to alert the user that 

the heater’s temperature is too low 

or too hi.  This should remain until the heaters are back within the allowed differential. 

 

CURRENT TEMPERATURES DISPLAY: 

 

1.  To view the heaters current temperature, press and hold the temperature button for 3 seconds.  

The display will then alternate between "toP" for top heater and its current temperature value. 

 

2.  To view the bottom heater current temperature, press the temperature button again.  The  

 
display will then alternate between "bot" for bottom heater and its current temperature value. 

 

3.  A press of the temperature button will cycle between top and bottom current temperatures. 

 

4.  To  exit  temperature  view  mode  and  return  to  previous  mode,  press  and  hold  the  temperature 

button.
