7.4 Description of Parameters
A4 Stand-By Blow-Down
If the controller or hygrostat demands no humidity from the
humidifier for a long period of time, it is advisable to flush out the
cylinder water. Using Parameter A4 Stand-By Blow-Down, the
time period is set after which the complete blow-down is auto-
matically performed. Water will not be fed into the cylinder until a
new demand signal is received (factory setting: A4 = 24h).
A17 Stand-by heating
The stand-by heating keeps the cylinder water warm when no
request is pending. The heating takes place if the safety chain is
closed at intervals according to parameter C16 for the interval
time A17 and according to parameter C17 for the on time A17.
C16 Interval time A17
The C16 parameter defines the length of the pause time
between the phases of the stand-by heating (active only if A17 =
Yes).
C17 On time A17
The C17 parameter defines the length of the heating period for
the stand-by heating (active only if A17 = Yes)

E3 Input Signal
To adjust the Comfort / Comfort Plus Control to a signal from an
external controller (U6= external controller), set Parameter E3,
also see Section: „Parameter Setting with Codes (P0=010) /
Advances Customer Level“. Similarly, set Parameter E3 to the
signal from the active humidity sensor when using an internal PI-
controller.
