1.2. LOW-VOLTAGE PART
The control panel and the execution part
should be connected with the cable
enclosed. The respective terminals should
be connected at both ends (i.e. GD-GD, V+-
V+, etc.). There is a connector at the panel
that could be easily detached.
The temperature sensor
should be
installed in the column according to its
manufacturer recommendations, leaving
circa 1 cm of the metal part protruding, if it
would be necessary to remove it (possibility
to hold it with pliers, etc.). The measurement
point of the column should be connected
with respective terminal of the panel.
DS18B20 circuits, operating in “normal” or
parasite power, are used as the temperature
sensors, the wire colors are important.
Ground (GND) is brown, Data line (viewed
from the connectors and label side) (DTA) is
white, supply is green. Mistake could
damage the sensor.
The LM electrovalve
should be connected to
the EZ connector. Polarization (+/-) is not
important. The electrovalve cable, due to
interferences created in it, should be shielded
and possibly short, should not be put in harness
with other cables. The controller enables control
of both NO and NC valves, appropriate
configuration to be done in menu.
VM valve
has an incorporated drive, thanks to
which, the controller may control its opening
rate independently. It should be connected to
the MZ connector. Connecting here not
recommended element may lead to the output
failure. Polarization is important, one of the wires is always red and it should be connected
to “+”. In case of inverted connection, the valve would operate in opposite direction making
the column correct operation impossible. Correct installation could be check by means of
input/output test (point 3.2), where the symbol “+” visible on the display means opening and
“-” – closing.
2. FIRST TURN ON AND CONFIGURATION
After making sure that everything is installed correctly, fill up the tank or disconnect the
heaters and turn on the supply. After a few seconds, the appliance should display the main
screen with the column diagram and temperature values in its particular elements. It is
recommended to perform a few operations in the service menu.
1. Restore factory settings (operation described in point 3.3).
