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.

Parameter Range Function
Act controlled hum --- Actual humidity used to control humidity. This may be
supply air or room humidity depending on setting and con-
trol type.
Setpoints --- Go to setpoint page with all setpoints related to humidity
control: Humidification, dehumidification, cascade control,
deviation alarm.
Cascade controller --- Displays humidification and dehumidification setpoint. Go
to cascade controller page with detailed settings.
Max controller sply 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.
Humidification 0...100 [%] Present value of humidity control. Go to parameter page
for humidity control.
Dehumidification 0...100 [%] Present value of dehumidification control. Go to parameter
page for dehumidification control.
Fan compensation 0...100 [%] Present value of the fan humidity compensation. Go to
parameter page for fan humidity compensation.
Summer disable – No
– Yes
Shuts off humidification in the summer (summer/winter
changeover must be enabled).
Dew point -64...64 [°C] Present calculated dew point.
Dew point dead zone -64...64 [°C] Dead zone for dew point. (Minimum discharge tempera-
ture for temperature control = present calculated dew
point + dead zone.
5.11.2 Humidity setpoints
Displays only the functions and values enabled in configuration 1 or configuration
2. All other functions are hidden.

[g/kg]
Actual calculated room or supply air dehumidification
setpoint (%rH or g/kg).
Act hum stpt 0.0...100.0 [%rH] oder
[g/kg]
Actual calculated room or supply air humidification set-
point (%rH or g/kg).
