Water vapor or air washer is used for humidification.
Enable and analog control signal planned for the humidifier.
A pump (with or without kick functions, with alarm and/or feedback signal) can be
enabled. Humidification can be locked in summer.
It can monitor achieving the setpoint or deviations over longer periods. Any even-
tual dehumidification can be limited when heat demand is too large.
It can also monitor and impact dew point and supply air temperature.

Functions
Function
Actual humidity used to control humidity. This may be
supply air or room humidity depending on setting and con-
trol type.
Go to setpoint page with all setpoints related to humidity
control: Humidification, dehumidification, cascade control,
deviation alarm.
Displays humidification and dehumidification setpoint. Go
to cascade controller page with detailed settings.
Go to page for max ctlr sply to parameterize the maximum
limit controller. You can limit the maximum allowable sup-
ply air humidity via the supply air humidity sensor when
room control only is enabled.
Present value of humidity control. Go to parameter page
for humidity control.
Present value of dehumidification control. Go to parameter
page for dehumidification control.
Present value of the fan humidity compensation. Go to
parameter page for fan humidity compensation.
Shuts off humidification in the summer (summer/winter
changeover must be enabled).
Present calculated dew point.
Dead zone for dew point. (Minimum discharge tempera-
ture for temperature control = present calculated dew
point + dead zone.
Function
Actual humidity used for control (%rH or g/kg depending
on control type). This may be supply air or room humidity
depending on setting and control type.
Actual calculated room or supply air dehumidification
setpoint (%rH or g/kg).
Actual calculated room or supply air humidification set-
point (%rH or g/kg).
