Operation - EBARA Ego 2 Tech Series Operating And Maintenance Manual

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.

5.2 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.
