7. Special Functions
Used to set basic items and expanded functions.
The settings in this menu should only be changed by a specialist.
Pump settings V1/ Signal V1
In this menu, the settings for the speed controlled output V1 are executed.
Type of pump/ Type of signal
The type of speed controlled pump used can be set here.
0-10V:
Control of special pumps (e.g. high efficiency pumps) through a 0-10V signal.
PWM:
Control of special pumps (e.g. high efficiency pumps) through a PWM signal.
Pump/ Profile
In this menu, the preset profiles for the pump can be selected or under “manual” all settings can be done personally. The settings
can still be changed after a profile has been selected.
Output Signal
In this menu, the type of pump is set: heating pumps have the greatest output with a small input signal, solar pumps in contrast
have very little output with a small input signal. Solar = normal, heating = inverted.
PWM / 0-10V off
This signal / this voltage is emitted if the pump is turned off (pumps with cable break detection require a minimal voltage / a min-
imum signal).
PWM / 0-10V on
This voltage / this signal requires the pump in order to turn on and to run at a minimum speed.
PWM / 0-10V max.
With this value, the maximum voltage level / maximum frequency can be specified for the highest speed of the energy saving
pump, which is used, for example, during the flushing or manual operation.

Speed control
If the speed control is activated, itSBMC offers the possibility through a special internal electronic system to change the speed of
pumps depending on the process.
This function should only be activated by a technician. Depending on the pump being used and the pump level, the
minimum speed may not be set too small, because the pump or the system may be damaged. The specifications from
the affected manufacturer must be observed for this! When in doubt, the min. speed and the pump level should be set
too high instead of too low.
Purging time
For this time, the pump runs with its full speed (100%) in order to guarantee a secure start-up. Only after expiration of this purging
time will the pump have a controlled speed and will switch, depending on the set variant, to the max. or min. speed. Speed.
Max. Speed
The maximum speed of the pump is determined here. During the setting, the pump runs in the respective speed and the flow can
be determined.
The specified percentages are variables, which may deviate more or less strongly depending on the system, pump
and pump level. 100% is the maximum possible power of the controller.
Min. Speed
The minimum speed of the pump is determined here. During the setting, the pump runs in the respective speed and the flow can
be determined.
