Activating the standard setback function:
When switching on the unit press the ”UP” button until
”ON” appears in the display. The setting is saved when
the "UP" button is released.Use the same process to
switch the unit off. ”OFF” will appear in the display (state
upon delivery).

The use of very fine soldering tips may have a negative
effect on reliable function.

Maintenance
The transition between the heating element / sensor and
the tip of the soldering iron may not come in contact with
dirt, foreign particles or become damaged, since this
affects the precision of the temperature control.

4. Equipotential bonding (not USA)

The various circuit elements of the 3.5 mm jack bush
make 4 variations possible:

Hard-grounded:

No plug (delivery form)

Equipotential bonding:

With plug, equalizer at center
contact
(impedance 0 ohms)

Potential free:

With plug

Soft-grounded:

With plug and soldered resi-
stance. Grounding via set
resistance value.

3. Commissioning

Assemble soldering iron rest (see exploded
drawing).Place the soldering iron in the safety rest.
Insert the soldering iron plug into the connection bush
(7) of the control unit and lock by turning to the right.
Check that the power supply corresponds to the specifi-
cations on the type plate and that the power switch (1) is
in the OFF position. On version that can be switched, set
the voltage on the selection switch (set in the factory to
240 V). Connect the control unit to the power supply.
Switch on the unit at the power switch (1). When swit-
ching on the unit, a self-test is carried out in which all
display elements (2) are switched on briefly. The electro-
nic system then switches automatically to the actual tem-
perature and displays this value. LED (5) illuminates.
These light emitting diodes are optical regulator moni-
tors. Constant illumination means that the system is
heating up. The blinking light signals that the operating
temperature has been reached.

Setting the temperature
The digital display (2) shows the actual value temperatu-
re. By pressing the UP or DOWN key (3) (4) the digital
display (2) switches to the setpoint. The setpoint can be
changed by tapping or by firmly pressing the UP or
DOWN button (3) (4) in the desired direction. Pressing
the button will change the setpoint quickly. The digital
display (2) returns automatically to the actual value
approximately 2 seconds after releasing the button.

Standard setback
If the soldering tool is not used within a period of 20
minutes the temperature will be automatically reduced to
a standby temperature of 150 °C (300 °F). After three
setback periods (60 min.) the ”AUTO OFF” function will
be activated and the soldering iron will be switched off.
