1.37 CIRCULATION PUMP
(SOLAR THERMAL SYSTEM
COUPLING KIT).
The units are supplied with circulating
pumps fitted with speed regulator.
These settings are suitable for most
systems.
In fact, the pump is equipped with
electronic control to set advanced
functions. For proper operation one
must select the most suitable type of
operation for the system and select
a speed in the available range, with a
focus on energy savings.
Display of operation status. During
normal operation the status LED (2)
is on green (flashing (FL) when it is in
stand-by), the four yellow LEDs (3) in-
dicate circulator absorption according
to the following table:

Selection of operating mode. To see
the current operation mode it is suffi-
cient to press button (1) once.
To change operation mode press the
button for between 2 to 10 seconds
until the current configuration flash-

all possible functions are scrolled
cyclically according to the table (Fig.
55). After a few seconds without doing
any operation the circulator memorises
the selected mode and goes back to
operation display.
- Constant curve: the pump operates
with a constant curve. The circulator
working point will move up or down
according to the system's demand.
- PWM profile: do not use this opera-
tion mode.
