Introduction
1.4.Water Pump
Operation status
When the circulator is running, LED 1 is green. The
four
yellow
LEDs
indicate the current power
consumption (P1) as shown in the table below. See fig.
1. When the operation mode is active, all active LEDs
are constantly on in order to differenti
ate this mode
from the select setting mode. If the circulator
is
stopped by an external signal, LED 1 flashes green.
Alarm status
If the circulator has detected one or more alarms, the
bi-
colored LED 1 switches from green to r
ed. When
an alarm is active, the LEDs indicate the alarm type as
defined in the table below. If multiple alarms are active
at the same time, the LEDs only show the error
with
the highest priority. The priority is defined by the
sequence of the table.
When there is no active alarm anymore, the user
interface switches back to operation mode.

Navigation
Key lock function
The purpose of the key lock function is to avoid
accidental change of settings and misuse.
When the key lock function is enabled, all long key
presses will be ignored. This prevents the user from
entering the "select setting mode" area and allows the
user
to
see
the
"
show
setting
mode
"
area
.
If you press the key lock for more than 10 seconds,
you can toggle between enabling/disabling the key
lock function. When doing so, all LEDs, except for the
red LED, will fl
ash for a second indicating that lock is
toggled.
User interface control modes for
UPM3 HYBRID variants
You can manage all UPM3 HYBRID variants with a
single push button and a LED interface.
You can select the following operation modes with the
push button.
The user interface shows the flashing LEDs in the
combination which is described in the tables below.
UPM3 FLEX AS
This circulator
is for either external PWM profile A
signal
control
or
speed
selection
.
You can define the maximum curve of the pump
operation range. With PWM signal, the circulator runs
at the corr
esponding speed. Without PWM signal, the
circulator runs at maximum speed.
