STARTUP (diagram C)
Before starting the device please read the previous sections, espe-
cially “Hydraulic Installation” and “Electrical connection”.
Follow next steps:
1. Only for type SW2 set the pump rated current intensity value.
- Press

- The current intensity value is displayed on screen, LED A lights up and
display is ashing.
- By mean of
and is adjusted the rated current reected in the
characteristics plate of the motor. See Note 1.
- Press
for validation.
2. Start the device by pressing
.
3. Set the cut-in (start) pressure:
- Press
during 3 seconds.
- The start pressure value is displayed on screen, LED START lights up
and display is ashing.
- By mean of
and is adjusted the start pressure from 0,5 to 7
bar (+ version=11 bar).
- Press
for validation.
4. Set the cut-out (stop) pressure:
- Press
during 3 seconds.
- The stop pressure value is displayed on screen, LED STOP lights up
and display is ashing.
- By mean of
and is adjusted the stop pressure from 1 to 8 bar
(+ version=12 bar).
- Press
for validation.
5. The unit is ready to operate but more optional adjustments can be set
through basic and advanced MENUS. See the next chapter.
Remark 1: it is important to introduce exactly the rated current
specied on the nameplate of the pump.

it is delayed the start in order to protect
the pump.

It allows setting a minimum operating
pressure under which the device would
determine dry-running operation. It is very
usefull in the basic model SWITCHMATIC
where there is no reading of current intensi-
ty drawn. See Note 2.

Remark 2:
Basic SWITCHMATIC 1/3 can only detect dry-running
operation through the minimum pressure. This means that
plumber must determine the water column of the installa-
tion, the start pressure of the pump and place the minimum
pressure below the start pressure.
It can also occur that pumping system is running out of its
curve so that the pump is unable to provide the minimum
pressure because the ow requirement is excessive. In this
case SWITCHMATIC 1/3 would activate a false dry-running
alarm.
If these concepts are not clear, it is preferable not congure
this protection or install the SWITCHMATIC 2 with accurate
and easy setting of dry-run detection.
Remark 3:
By choosing “no” (normally open) it will operate as an auxi-
liary pressure control element in the suction of the pump. It
will restart when the suction pressure reaches the congu-
red PStart.
Example: - PStop: 0,9 bar
- PStart: 1,2 bar
