SETTING THE UNIT TO “IDLE MODE” 
 
Setting the unit to “Idle Mode” will internally turn off power to the heater/chiller assembly 
and allow the sample to heat up or cool off naturally to ambient conditions.  It is essentially 
turning the set point off, which is why the set point on the LCD indicates “off” when the unit 
is in Idle Mode.  Idle mode may be set and cleared in different ways and the previous set 
point value may be cleared or retained as described below.  See Figure 5 and Figure 6 for 
details on setting and clearing Idle Mode using the menu. 
 
 
The unit will enter Idle Mode in two ways: 

1.  By using the Menu option (“Set Idle Mode”)  
2.  By setting the “Auto-Off” option to “yes” in the Timer Options menu.  The IC25/35 

will enter Idle mode when the countdown timer reaches 00:00:00 at the end of a 
timer period or when a program has ended. 
 

The unit will exit Idle Mode in the following ways: 

1.  By pressing either arrow button –the set point will be set to 20C. 
2.  By selecting “Clr Idle Mode” from the menu—the set point before the unit was set 

to Idle Mode will be restored
