1. Functions of the controller
The following control units are available depending on
the pumping capacity:
CERTO FU 750 =750 Watt
CERTO FU 1500=1500 Watt
Special features:
the control units can be used worldwide
we have followed all the guidelines available to us in
the design of the control unit
it is therefore the most up-to-date generation of con-
trol units
the control unit is operated via only three keys. Re-
sults and queries are displayed on the illuminated
single-line display
Once the mains power has been switched on, the
control unit is ready for immediate operation if it is
connected
Faults are shown on the display

This sets the clock that controls the error log. Pressing , again will open the menu item “Manual draining”.
Prior to long downtimes, the pump station can be drained via “Manual draining”. Pressing the left selection key
() will open the solenoid valve underneath the water filter. Pressing the Enter key( ), will stop the process,

To access the main menu, the code 00111 must be entered. This code request protects against unauthorised
access. It is therefore advisable to keep these operating instructions in a safe place.
Main menu:
Confirming with ( ) takes you to the menu item “Operating mode” for selecting the control option.
Depending on the on-site conditions, you can choose between external control via a control signal, manual
operation and humidity control (with optional humidity sensor). The operating mode can be changed by pressing
the left ( ) and right selection key ( ).
After selecting the control option, the entry must be confirmed with the Enter key ( ).

Manual operation
If “Manual operation” has been selected, a manual target value between 3 Hz and the factory-set maximum
frequency can be specified. The manual target value is set by pressing the selection keys.
This value is confirmed by pressing the Enter key .
External control.
If “External control” has been selected, the following display appears:
The start point can be set from 0-40% and relates to the control signal. Example: If set at 10%, the control unit will
only react to a control signal of 1 Volt. As a result, interfering voltages, which can lead to inadvertent operation of the
control unit, are suppressed.

If “Humidity control” has been selected, the following display appears:
Here, the relative humidity the humidifier can achieve is set between 10 % and 95 %.
The PI-controller is activated duringhumidity control. This ensures that the set target value remains constant. The
Klingenburg humidity sensor is required for this purpose. The gain factor is set here.
Attention:
The value must not be set >1.0, since this could lead to strong sub-harmonics and harmonics.
This controls the reaction time of the control. The greater the time, the slower the control.

changes should be made.

Minimum frequency
The minimum frequency is factory set. The nozzle pressure should be set at a minimum of 5 bar in any humid-
ification situation. Changing this frequency means that humidification is not guaranteed but the humidifier is
operating all the same. Controllability is also compromised This setting value is calculated at the factory and
preset and checked during a trial run. Frequency range: 3-20 Hz. Changes can cause damage to the humidifier.
Maximum frequency
The maximum frequency is factory set. The humidifier is designed for a specific humidification capacity. To
achieve this value, the complete humidification system is synchronised. This setting value is calculated at the
factory and preset and checked during a trial run. Frequency range: 22-80 Hz. Changes can cause damage to
the humidifier.
Pressing the Enter key ( ) in the setting values of “Maximum frequency” will take you to the menu item Fre-
quency limit. If excessive humidity occurs or the water consumption is too high, the frequency can be adjusted
here. It is important to note that the maximum frequency remains unchanged.

Autostart function
The Start and Stop button under the display screen has priority. The “Autostart on” function puts the control unit
in Run mode, when menu navigation is completed and after a control unit reset, i.e. if approval is given and a
control signal is present, the control unit starts the humidifier up again.
If “Autostart off” is programmed, the control unit must be activated via the Start button ( Start ). This setting is
useful for maintenance or during longer downtimes.
Power-up time
The power-up time is factory set. This is the time required to reach the designed maximum speed. This is to
ensure that the components of the drive system are not put under unnecessary strain.
This value is preset at 15 seconds. Years of experience have shown that this can extend the service life. Adjust-
ment range: 1-30 s. Changes can cause damage to the humidifier.

Power-down time
The power-down time is factory set. In contrast to the power-up time, this is the time required for the motor to
get from maximum speed to zero. Again, the aim is to protect the mechanical components. This value is preset
at 10 seconds. Adjustment range: 1-30 s. Changes can cause damage to the humidifier.
Line pressure fault message
If several appliances are using the osmosis system and are running simultaneously, the line pressure can drop
below 1.6 bar. This causes the humidifier to stop or switch off. In this menu item, the tripping time of the line
pressure fault message can be extended (up to 30 minutes) or the fault message can even be switched off (Fault
message off). This means that the humidifier is on standby for longer or all the time, when the line pressure is
above 2 bar.

Rinse interval
To ensure hygienic operation of the humidifier, the control unit has an automatic rinsing cycle as standard. The
rinse interval is preset at the factory for 48 hours. The value is adjustable between 1 hour and 96 hours. This is
the period between two rinsing cycles. Rinsing is activated if the humidifier is enabled via terminals 11 and 12,
but no humidification is provided via the control signal or the humidity sensor. Changes lead to increased water
consumption and should only be made if bacterial growth due to stagnant water is found during the hygiene
inspection.
Purge duration
The time of the actual purge process is adjustable between 10 and 1800 seconds. The factory
default setting is 180 seconds. The nozzle assemblies are rinsed for half the set time. Afterwards the solenoid
valve under the filter opens and the filter is flushed.

Drying run
The control unit is equipped with a delayed shut-off control for drying the humidifier. This function allows an
enforced shut-off delay of the ventilation system. During operation and after the pump has been switched off, the
floating output is switched on for the set time. Adjustment range: 15 - 120 min. or off.
Step switch
For large humidifiers that use a lot of water, it may be useful to switch the nozzle assemblies in groups. In
transitional periods when less humidification is required, this can be achieved with fewer nozzles and higher
pressure. Depending on the frequency, the nozzle assemblies can be switched on in succession via high pressure
solenoid valves.

Reset service message
This menu item is only available, if the “Service” message appears during operation and the recom-
mended oil change intervals have been exceeded. Once the oil change has been carried out, the mes-
sage can be reset by pressing the left selection key ( ) and confirming with the Enter key ( ),
thus initiating a new interval cycle. Proof that the oil change has been carried out must be provided.
Attention! Resetting the service message without an oil change will damage the pump and void the warranty.
