A Automatic mode (factory setting)
In automatic mode the pump automatically sets the operating pressure, depending on the hydraulic
system. By doing so, the pump finds the optimal operating position.
This mode is recommended in most systems.
The parameters cannot be set; they can only be scrolled through.
Proportional pressure (figure 5.3a)
The pump maintains the pressure with relation to the current flow. The
pressure is equal to the set pressure (H set on the drawing) at maximum
power; at 0 flow it is equal to 50% of the set pressure. In between, the
pressure changes linearly, relative to the flow.
In regulated mode we can only set the pump pressure (H set on the
drawing). We can only scroll through the other parameters.
Constant pressure (figure 5.3b)
The pump maintains the currently set pressure (H set on the drawing),
from 0 flow to maximum power, where the pressure begins to drop.
At constant pressure, we can only set the pressure (H set on the drawing)
which the pump will maintain. We can only scroll through the other
parameters.
Constant revolutions (figure 5.3c)
The pump operates with the currently set revolutions (RPM set on the
drawing).
In the unregulated mode, we can only set the revolutions at which the
pump will operate. We can only scroll through the other parameters.
Night mode
When the pump operates in night mode, it automatically switches between the selected operating curve
in the mode and night curve. The transition to the night mode depends on the media temperature in the
system.
When the night mode is prepared for operating, its icon illuminates and the pump operates in the
selected operating curve of the mode. When the pump identifies the media temperature fall by 15-20C°
(approximately during 2 hours), the icon starts to blink and the pump switches to the night curve. When
the media temperature rises again, the icon stops blinking and the pump passes over to the operating
curve in the selected operating mode.
The night mode operates only in combination with the above indicated modes. It is not an independent
operating mode.
5.6. Setting the pump to the factory settings
To restore factory settings to the pump, it is necessary to press and hold all three keys for 5 seconds. The pump
is set to the automatic mode of operation. The previously set values for pressure and revolutions will be deleted.

Night mode
When the pump operates in night mode, it automatically switches between
the selected operating curve in the mode and night curve. The transition to
the night mode depends on the media temperature in the system.
When the night mode is prepared for operating, its icon illuminates and the
pump operates in the selected operating curve of the mode. When the pump
identifies the media temperature fall by 15-20C° (approximately during 2
hours), the icon starts to blink and the pump switches to the night curve.
When the media temperature rises again, the icon stops blinking and the
pump passes over to the operating curve in the selected operating mode.
The night mode operates only in combination with the above indicated
modes. It is not an independent operating mode.
5.6. Setting the pump to the factory settings
To restore factory settings to the pump, it is necessary to press and hold all
three keys for 5 seconds. The pump is set to the automatic mode of operation.
The previously set values for pressure and revolutions will be deleted.
5.7. Twin-head pumps NMTD SMART (C)
Pumps have a common hydraulic housing that is equipped with a change-
over flap and two pump heads, separately connected to the electrical grid.
Pumps that communicate with each other. – NMTD SMART C
Pumps without an communication option – NMTD SMART
With this use, we recommend that night mode isn't used.
