Instruction manual V 2.3

PWM 230 - PWM 400 - PWM 400/7.5
Instruction manual
-
Without changing the amount of water taken, change the direction of rotation directly by simultaneously
pressing the
and
keys (see sec. 7.2.3) and take note of the pressure again while the pump
is running.
-
The right direction of rotation is obtained when pressure is maximized.
- Press
to stop the pump.
2nd mode
- Open a user, start the pump by simultaneously pressing the
keys and take note of
the pressure(if a manometer is not available, you can display the pressure “UP” by scrolling the menu
with the
key).
-
Without changing the amount of water taken, change the rotating direction “rt” with the
and
keys while the pump is taking water from the user circuit and the pump is running. Take note of the
pressure again.
-
The right value of “rt” is obtained when the pressure is maximized.

7.2 Controls
When PWM is in manual mode, it is always possible, irrespective from the displayed parameter, to perform
some controls as described in the following sections.
7.2.1
Temporary start of the electro pump
Simultaneous pressure of the
keys causes the pump’s start at FP frequency and the running
status persists as long as the two keys remain pressed.
When the pump is ON the display blinks quickly (200mSec ON, 100mSec OFF).
When the pump is OFF the display blinks slowly (400msec ON, 100mSec OFF).
7.2.2
Quick-start of the pump
Simultaneous pressure of the
keys for 2 seconds causes the pump’s start at FP
frequency. The running status persists until the
key is pressed.
When the pump is ON the display quickly flashes (200mSec ON, 100mSec OFF).
When the pump is OFF the display slowly flashes (400msec ON, 100mSec OFF).
