SINGLE BUTTON FUNCTIONS 

Table 5: single button functions 

BUTTON 

FUNCTION 

 

Type Controller menu: keep this button pressed for at least 3 sec within 1 min after power on to enter the “Type Controller Menu” (tC). 
AUX output control: Switches the AUX relay output (if enabled as such).  

 

Manual Defrost: keep this button pressed for 3 s to start a manual defrost cycle. The defrost icon will illuminate. (Not possible if parameter tC 
= 1 or 7). 

 

Display current set point: after pressing and releasing this button, the set point will be displayed for 5 sec. This will not allow the set point to 
be altered. 
Changing set point value: keep this button pressed for at least 2 sec. Set point change mode is entered indicated by the small led’s 
flashing.  Change the set point using the UP and DOWN buttons. The new value can be stored either by pressing SET button (the instrument 
restores temperature display) or by waiting the exit time-out to expire (15 sec). 

 

(UP): to see the max stored temperature; in programming mode it browses the parameter codes or increases the displayed value. 

 

(DOWN): to see the min stored temperature; in programming mode it browses the parameter codes or decreases the displayed value. 
Keep press 3sec just after powering on the device (and within the first 60sec) to start automatic probe recognising. 

 

Keep pressed 2 sec to switch the instrument off when the parameter onF 1

.

COMBINATION 

FUNCTION 

 

 

 

Lock & unlock the keyboard: keeping both buttons pressed for 3 sec will lock or unlock the keyboard. The display 
will flash PoF or Pon for a few seconds to confirm locking or unlocking respectively.

Enter programming mode: keep both buttons pressed for 3 sec, release them and then press them again for 8 sec. 
The first label of Pr2 level will be displayed.

PROGRAMMING MODE  

9.1

 

USER PROGRAMMING LEVEL – PR1 

To enter programming level Pr1 (user programming level), keep both SET and DOWN buttons pressed for 3 sec. The first parameter 
label  will  appear.  Browse parameter list by using the UP or DOWN keys. Press SET to see a parameter’s current value and UP or 
DOWN keys to alter its value. Press SET to confirm change (the display will blink for 3 sec and then the next parameter will appear) or 
by waiting for the menu timeout to expire (15 sec). If no parameter is available for changes in Pr1 level, a noP label will be show. 
 

9.1

 

PROTECTED PROGRAMMING LEVEL – PR2 (ALL VISIBLE PARAMETERS CAN BE FOUND HERE) 

First enter Pr1 level (as described above) then with any parameter label displayed keep both SET and DOWN buttons pressed for 8 
sec.  The  first parameter label will appear. Browse parameter list by using the UP or DOWN keys. Press SET to see a parameter’s 
current value and UP or DOWN keys to alter its value. Press SET to confirm change (the display will blink for 3 sec and then the next 
parameter will appear) or by waiting for the menu timeout to expire (15 sec).  
From  Pr2  level  it  is  also  possible  to  add  or  remove  any  parameter  to  /  from  Pr1  by  pressing  both  SET  & DOWN while its label is 
displayed.  Accessibility of any particular parameter via Pr1 level is confirmed by the alarm LED lighting up while its label is displayed 
 
WARNING:  if  no  button  is  pressed  for  15  sec,  any modified value will be stored into memory and the controller will return to the normal 
display mode.
