PrP: Printer presence. (Yes or no) Enables or disables the printer.
ItP: Printing interval. (0.0 to 30.0). Sets the print interval.
PbP: Print probe selection. (iP: only the food probe selected. rP: only the air probe selected. irP: Food and Air
probe selected. irE: All probes selected).
PtH: (yes or no) Enables or disables the printing during the holding phase.
tSt: Starts the controller self test function.
Out: Exit from the menu.
Parameter Access and modification
To access the parameters firstly enter the function menu by pressing the “SET” and “DOWN” keys for 3 seconds. Scroll through the labels and select “PR2”, press the “SET” key. “PAS” label flashes for a few second followed by “0 _ _” with the zero flashing. The access code is ‘ 321’.
Use the “UP” or “DOWN” key to input the first number of the security code in the flashing section, confirm by pressing “SET”.
Repeat the operation for the second and third digits. If the security code is correct “Hy” will be displayed.
NOTE: if no key is pressed for 15 seconds the controller reverts to displaying the room temperature.
