2.4 Timer Drain Programming Mode
1. Press the “Drain Interval Program” button (the
“Condensate 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
Program” button (this will store the new setting and exit
the program).
4. Exiting the Program will cause the Timer Drain to
discharge and begin a new cycle.
NOTE:
Failure to perform step 3 within 25 seconds of
completing 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
capacity would prevent downstream flooding. Condensate
will drain completely within a couple of cycles. (Manually
pressing the “Push-to-Test” button would drain bowl
immediately)
