BUTTON

A short press on the button will change the pump curve from the first to the second and then to the third curve.
After the third curve is reached and the button is pressed again, the pump mode will change and the first curve
will be selected. If the pump is in standby, then it will start with a short press.
A long press will turn on standby mode. In this mode, the pump will occasionally turn on, with minimal speed.
The pump will blink its current mode.
Auto mode does not have any pump curve to select.
Night mode works in combination with other pump modes. After the third curve of constant speed is selected
and button is pressed, night mode will be turned on together with auto mode. Every change of curve and mode
until the third curve of constant speed will have night mode turned on. After that, if the button is pressed, night
mode will be turned off.

OPERATION

The pump can work in different modes of regulation. Pump mode is selected depending on what kind of system
the pump is working in.
Auto 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 for most systems.
No curves are available in this mode.
Proportional pressure (radiator heating)
The pump maintains the pressure with relation to the current flow. The pressure is equal to the
set pressure (3 preconfigured curves) at maximum power; at 0 flow it is equal to HQ % (default
60%, of the set pressure. In between, the pressure changes linearly, relative to the flow.
Constant pressure (underfloor heating)
The pump maintains the currently set pressure (3 preconfigured curves), from 0 flow to maximum
power, where the pressure begins to drop.
Constant speed
The pump operates with the currently set speed (3 preconfigured curves).
Night mode
When the pump is operating in the night mode, it automatically switches between the current
mode and the night mode. Switching occurs based on the temperature of the medium. While in
night mode the night mode icon is turned on and the pump operates in the 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,
the blinking stops and the pump goes back to the previously chosen operation mode.
Night mode can only work in compliment to other modes and is not a mode that can run by itself.
