OPERATION

The pump can operate in 5 different modes. We can set the pump in the most appropriate mode, depending on
the system where the pump operates.
The pump modes:
Automatic mode (factory default),
•
• Proportional pressure,
• Constant pressure,
Constant speed,
•
• Combined mode (all mode indicators are off) – only available on NMT(D) SMART C.
Automatic mode
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
The pump maintains the pressure with relation to the current flow. The
pressure is equal to the set pressure (Hset on the drawing) at maximum power; at 0
flow it is equal to HQ % (default 50%, HQ % can be set on the pump webpage) of the
set pressure. In between, the pressure changes linearly, relative to the flow.
In regulated mode we can only set the pump pressure (Hset on the drawing). We
can only scroll through the other parameters.
Constant pressure
The pump maintains the currently set pressure (Hset on the drawing), from 0 flow
to maximum power, where the pressure begins to drop.
At constant pressure, we can only set the pressure (Hset on the drawing) which the pump
will maintain. We can only scroll through the other parameters.
Constant speed
The pump operates with the currently set speed (RPMset on the drawing).
In the unregulated mode, we can only set the speed at which the pump will operate. We
can only scroll through the other parameters.
Combined mode
Multiple limits can be set only over the web interface. None of the other modes are on.
Night mode
When the pump is operating in night mode, it automaticly switches between the current mode and night
mode. Switch occurs based on the temperature of the medium. While in night mode its icon is turned on and the
pump operates in chosen mode. If the pump senses drop in temperature of the medium for 15 -20 °C (in time
frame of 2 hours), icon starts to blink and the pump switches to night mode. When the temperature of the
medium rises, blinking stops and the pump goes back to previously chosen operation mode.
Night mode can only work in compliment to other modes and is not a mode that can run by itself.
