A turn can last from a minimum of 1 minute to a maximum of 23 hours and 59 minutes.
After the last turn, press the
down arrow button
to move to the next menu:
Program
THRESHOLD FLOW
0,0 l/s
10% hysteresis
100 l/pulse
Press the
OK button
to modify the threshold flow, use the
arrow buttons
to set the value, and then press
the
OK button
to modify the hysteresis. Use the
arrow buttons
to set the value, and then press the
OK
button
to modify the pulse weight. Use the
arrow buttons
to set the value, and then press the
OK button
to finish the programming and memorize the set values in this menu.
0.0 l/s means the threshold is disabled. The enabled threshold controls the flow rate only if the valve is
ACTIVE (automatic mode). If the flow rate exceeds the threshold, it DEACTIVATES the valve. The valve
ACTIVATES again once the flow rate falls below the threshold.
In case of instable flow rate, the adjustable hysteresis avoids activating or deactivating the valve
continually.
The pulse weight depends on the type of volume meter connected to the BASE. Program the pulse weight
according to the volume meter for a correct flow rate measure.
Press the
down arrow button
to enter the last menu and select the type of meter (ultrasonic/non-
ultrasonic).
Press the
OK button
to enable/disable the ultrasonic meter.
Press the
OK button
to confirm.
