2.4 Timer Drain Programming Mode
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).
4. Exiting the Program will cause the Timer Drain to dis
-
charge and begin a new cycle.
NOTE:
Failure to perform step 3 within 25 seconds of com
-
pleting step 2 will cause the unit to revert back to the previous
setting.
NOTE:
In the event of a brief or extended period of power
loss, the unit will retain the existing program setting and will
begin a new cycle once power is reapplied. Had drain been
ready to drain before the loss of power, the drain bowl’s capac
-
ity would prevent downstream flooding. Condensate will drain
completely within a couple of cycles. (Manually pressing the
“Push-to-Test” button would drain bowl immediately)
