Installation and Operation Manual
Draining when using softened water
When using softened water and when the program code indicates
either “S” or “T” for the “Type of water level control” being used
(see the configuration string nomenclature on Pages 32 and 33),
then draining occurs for a one-minute duration every 28 days 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-logic
3
controller is equipped with 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 Set Up screen.
End-of-season drain
If there is no call for humidity for a preset time period, the
humidifier is placed in End of Season (EOS) mode. When the
unit enters EOS mode, the drain valve remains open for ten hours
to allow the tank to drain and then closes. When the humidifier
receives a call for humidity after the end-of-season drain, the tank
refills and the humidifier resumes normal operation.
The amount of inactivity time needed before the humidifier enters
End Of Season is adjustable through the Set Up screen on the
keypad/display (Inactivity Until EOS). This option is available only
on units equipped with automatic drain and fill valves.
