Control functions (code 241)
Warning! Only experts should change these settings! See user parameters for login procedure.
Parameter Description
CP 00
Minimum set point limit in humidification mode
CP 01
Maximum set point limit in humidification mode
CP 02
Minimum setpoint limit in de-humidification mode
CP 03
Maximum setpoint limit in de-humidification mode
Controls configuration
CP 04
Economy humidity shift:
The comfort (occupied) set point is shifted by the value set here. If
humidifying is active the comfort set point will be decreased, if dehumidifying
is active, the set point will be increased. (Enable with UP04.)
CP 05
This parameter is only used if CP10 = 0
Dead zone span:
The Dead Zone Span defines the deviation set point to input value required for
the controller to switch from humidifying to dehumidifying or vice versa. The
output is off while the measured value is within the dead zone span. A
negative dead zone is not possible.
CP 06
This parameter is only used if CP10 = 0
Delay on humidify – de-humidify change over
CP 07
Switching Hysteresis
Defines the difference between switching on and switching off an output. A
small hysteresis will increase the number of switching cycles and thus the wear
on associated equipment.
CP 08
Delay OFF (Minimum running time) [MM:SS]
Prevents a too short running cycle for the control output by setting a minimum
running time
CP 09
Delay ON (Minimum stopping time) [MM:SS]
Prevents a too short running cycle for the control output by setting a minimum
stopping time
Output configuration
CP 10
Configuration of control mode
0 = Both Humidification and de-humidification
1 = W04 = Humidification only
2 = W05 = De-humidification only
CP 11
Enable fan (only if CP 10 ≠ 0)
CP 12
Start delay for fan [MM:SS]
(Time the fan runs before control output starts)
CP 13
Stop delay for fan [MM:SS]
(Time the fan keeps running after control output stops)

Fan delay
Once there is an output demand, the humidistat will first activate the fan, wait the required start delay time (CP12)
and then activate the control output. This will ensure stable air for humidification or de-humidification.
The control output will be switched off when the set point is reached. The fan keeps running until stop delay (CP13)
has expired. This will ensure that no left over humidity remains in the device or its ducts.
