Operation
Draining when using softened water
When using softened water draining occurs for a one-minute
duration after a period of time based on 1000 hours of 100%
operation to remove residue from the drain valve mechanism. End
of season draining occurs as described below.
Skim timer
With a potable or softened water configuration, the Vapor-logic4
controller has a skim timer. This timer is activated at the end
of each fill cycle. The timer keeps the fill valve open (for a
user-determined amount of time after the tank has filled) to skim
minerals off the water surface. The skim time is adjusted through
the Setup menu.
End of season drain
If there is no call for humidity for a user-defined time period,
the humidifier performs an end of season (EOS) drain where the
drain valve remains open for ten hours to allow the tank to drain
and then closes. If the humidifier receives a call for humidity after
the ten-hour end of season drain-down period has begun, the
controller stops the end of season draining, the tank refills, and the
humidifier resumes normal operation. The user-defined inactivity
time period (idle time) is defined in the end-of-season drain
section of the Setup menu. This option is available only on units
equipped with electric drain and fill valves.
