    2.4 Timer Drain Programming Mode Dew Point Drain Interval Temperature Selector Indicator Condensate Draining (Flashes in programming mode) (LED illuminated Drain Interval indicates drain Program cycle setting) 1. Press the “Drain Interval Program” button. The “Conden- sate Draining” LED will start to flash, and the illuminated LED on the “Dew Point Temperature Indicator” will identify the factory setting for “Minutes Between Drain Cycles.” (See Table 1) 2. Press and release the “Drain Interval Selector” button to sequence the “Minutes Between Drain Cycle LED’s” from left to right until reaching your selection. The “Red” LED is not used (Reference Table 2 for “Drain Cycle Intervals”) 3. To initiate the new setting, press the “Drain Interval Pro- gram” button (this will store the new setting and exit the program).
