OPERATION STATUS
In performance view, the first LED is always green as long as there are no alarms.
In the settings view, it can be either green or red, indicating internal or external
control. The four yellow LEDs indicate the current power consumption (P1) as
shown in the figure and table below.

Operation area according to performance load
When the operation mode is active, all active LEDs are constantly on in order to
differentiate 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 red. 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.

SETTINGS VIEW
You can switch from the performance view to the settings view by pressing the push
button. The LEDs indicate the actual setting. The settings view shows which mode con-
trols the circulator. No settings can be made at this stage. After 2 seconds, the display
switches back to performance view.
If LED 1 is green, it indicates operation or internal control. If LED 1 is red, it indicates
alarm or external control. LED 2 and 3 indicate the different control modes and LED 4
and 5 indicate the different curves.

The Circulation Unit is equipt with an information display containing a leaflet that
graphically explains what kind of application the unit is controlling. It gives you also
the possibility to write in notes and leave your business card behind.
Just remove the display glass and select the suitable information.
MAINTENANCE
The circulation unit does not require any specific maintenance under normal
conditions. Althoug it is important to annually check the entire system. Pay
specially attention to all threaded or soldered connections and the potential
occurrence of limestone sedimentation.
WARNING Switch of the electric supply before any operation. Pay attention to
the hot water contained.
SPARE PARTS
Spare parts are ordered via ESBE customer service.
In order to avoid queries and incorrect orders, all data on the name plate should
be submitted for each order.
