GENERAL
Read carefully the instructions before installing this unit.
Verify the technical characteristics of the motor in order to
assure the compatibility with the device.
DESCRIPTION (diagram A)
T-Kit SWITCHMATIC is an electronic pressure switch with
digital manometer integrated in a 3-ways fitting with inner
non-return valve. It manages the start and stop of a single-
phase pump up to 2.2kW (3
pressures are easily adjustable through the users control
panel.
Wiring is analogous to the traditional electromechanical
switch.
It can operate as a differential pressure switch and as reverse
pressure switch.
Unit T-Kit SWITCHMATIC 2 in addition to all the features
of the basic T-Kit SWITCHMATIC includes instantaneous
reading of current drawn. This patented system controls
and manages the overcurrent, dry-run operation and fast-
cycling.
Unit T-Kit SWITCHMATIC 2 in addition to all the features of
individual assembly includes the option to be synchronized
to another unit T-Kit SWITCHMATIC 2 managing and pro-
tecting 2 pumps operating in cascade with alternated star-
ting sequence.
CLASSIFICATION AND TYPE
According to IEC 60730-1 and EN 60730-1 this unit is a
control sensor device, electronic, independent assembly,
programming type A with action type 1B (microdisconnec-
tion). Operating value: I <20% I learned. Pollution degree 2
(clean environment). Rated impulse voltage: cat II / 2500V.
Temperatures for ball test: enclousure (75) and PCB (125).
OPERATING CHARACTERISTICS (diagram C)
• Adjustable cut-in and cut-out pressures.
• Integrated digital pressure gauge with bar and psi indi-
cation.
• Inner pressure transmitter.
• Inner non-return valve.
• Dry-run protection:
• Through minimum adjusted height for basic T-Kit
SWITCHMATIC 1.
• Through the instantaneous current consumption in
case of T-Kit SWITCHMATIC 2.
• Overcurrent protection (only SW2).
• ART Function (Automatic Reset Test). When the device
has stopped the pump by the intervention of the dry-
running protection system, the ART tries, with scheduled
basis, to re-start the pump in order to restore the water
supply. See "ART. Automatic reset function". Must be
activated in the step 6 of the ADVANCED MENU (Ar1).
• Fast cycling: when the hydropneumatic tank has lost too
much air and, consequently, frequent start-stop cycles
are produced this alarm is activated and is delayed the
start of the pump. Must be activated in the step 2 of the
BASIC MENU (rc1).
• Manual start push-button (ENTER).
• 3 operation modes: differential, reverse and synchroni-
zed (only SW2).
• Control panel with 3-digit display, LED indicator lights
and push-buttons.
• Available settings:
• Stand-by mode.
• Minimum period between fast cycles.
• Start and stop delay.

HYDRAULIC INSTALLATION (diagram A)
T-Kit SWITCHMATIC equipment must be threaded to
the pump outlet G1".
There are 2 outlets G1" female for the hydropneumatic tank
and the hydraulic net.
- If the tank is threaded to the outlet at 180 °, it should not
be larger than 25 l.
- If the tank is threaded at the outlet at 90 °, it should
not be larger than 5 liters.
- If a flexible pipe is used for an horizontal tank and,
consequently, does not support weight, there is no
dimensional limitation.
Before connecting the T-Kit SWITCHMATIC verify that the
hydraulic system is properly installed, especially if the hy-
dropneumatic tank is pressurized.
ELECTRIC CONNECTION (diagram B)
The electric connection must be performed by qua-
lified personal in compliance with regulation of each
country.
When carrying out the electrical connection it is compul-
sory to use a differential switch of high sensitivity: I = 30
mA (clase A o AC). It is compulsory to use a magnetother-
mic switch adapted at the motor load.
Before doing manipulations inside the device, it must be
disconnected from the electric supply.
Wrong connection could spoil the electronic circuit.
The manufacturer declines all responsability in dama-
ges caused by wrong connections.
Check if power supply is between
If you have purchased the unit without cables follow
gram B:
• Use cables type H07RN-F 3G1 or 3G1,5 with section
enough to the power installed.
• Do the pump connection U, V and .
• Do the power supply connection L1, N and .
• The earth conductor must be longer than the others.
It will be the first one to be mounted during the as-
sembly and the last one to be disconnected during the
dismantling. The earth conductors connections are
compulsory!
