3.3 Heater/Stirrer Programming
3.3.1
Setting Operational Parameters and Functions
All operational parameters and functions are programmed and controlled via the Controller’s software settings. Most are
user-adjustable and easily accessed via the Main Menu. The Main Menu is accessed by rotating the Select/Set Knob. A
particular Main Menu item is selected by pressing the Select/Set Knob when that item is highlighted.

Setting and Starting the Timer
The Timer sub-menu allows you to program the Controller’s timer to alert you once a specific period of time has
elapsed. It should be used as you would an external timer.
IMPORTANT: The Timer is independent of temperature control. It does not start or stop heating/cooling. The Controller
continues maintaining temperature at the set point even though the designated time period has elapsed.
To set the timer, access Timer on the Main Menu, select Set, and then enter the desired period of time. The timer’s
audible signal can be turned On and Off via the selection named Beep on the Timer sub-menu.
To start the timer, press the Timer button on the Controller’s front panel. A timer icon and Beep icon (indicating either On
–
•
or Off – the icon with an X through it), along with a countdown timer, will appear on the bottom of the LCD. The Timer
LED will light continuously.
Once the designated time period has elapsed, the audible signal (if enabled) will sound and the countdown timer will
display the amount of time which has elapsed since the designated time period ended. The timer LED will flash.
To silence the audible signal and/or clear the timer display from the LCD, press the Timer Button.
The timer may also be paused at any time during the countdown period by pressing the Timer Button. When this occurs,
the Timer LED will flash and the word “Paused” will appear on the display adjacent to the countdown timer.
