DESCRIPTION AND TECHNICAL DATA
DESCRIPTION
Temperature controller for heating applications such as
heating cables in industrial plants, with additional alarm relay.
Design for DIN rail mounting. Temperature sensor Pt100 in
3- or 2-wire technology, thermocouples type J, thermocouple
type K or standard signals (0/2V - 10V, 0/4mA - 20mA). Many
dierent control functions.
Operating status LEDs
LED 1 = operation (heating on)
LED 2 = ramp mode
LED 3 = signaling relay (alarm 2)
LED 4 = alarm relay (alarm 1)
Soft start
When using the internal hybrid relay as a switching output, a
soft start phase is initiated for 20 seconds before each cold start
of the load relay (with 14% power via triac output) in order to
reduce the starting current.
Digital inputs
DigIn1 is used with structure switch position S07 – 2 (external
controller release) and serves as an external release of the load
output.
DigIn2 is used with the structure switch position S04 - 5 (limiter
function) and serves as an external unlocking.
DigIn3 is used with structure switch position S03 – 6 (W1/W2
switchover) and is used to switch between W1 and W2.

DECLARATION OF CONFORMITY
•Electrical connection / commissioning must be carried
out by a qualied electrician.
•The relevant local safety regulations must be observed.
•Observe the connection values according to the rating
plate.
•Avoid tensile stress and torsion of the connected
cables
CAUTION
WARNING
Before starting work on
heating or connection cables or connection
terminals is to ensure that the corresponding circuit is
switched o and is secured against unintentional
restart
CAUTION
The sensor lines must be shielded
when extended, the shielding must be grounded on
one side close to the controller. The line must not be
laid parallel to lines carrying mains voltage. The total
line resistance must not exceed 10 ohms.
After switching on the controller, the
display shows the current actual value.
NOTE
Storage should be in a dry place at an
ambient temperature of 0°C to 50°C.
NOTE
The WEEE logo (shown above) indicates
that this product should not be disposed of with your
household waste.
You can obtain more information on disposal and
restoration of electrical and electronic
old devices and collection points from your local was-
te disposal company or from the manufacturer where
you purchased the product.
NOTE
Upon receipt of the goods, check the controllers and accesso-
ries and compare the data on the nameplate with the data on
the delivery note to ensure that the correct material has been
supplied.
We declare that the product described fully complies with
the directives 2014/35/EU, 2014/30/EU and 2011/65/EU. If you

GENERAL
After switching on, the type number ("CU2") and software ver-
sion of the device appear and after approx. three seconds the
measured actual value. By pressing the arrow keys / you
can scroll through the parameters P01 – P08 (purely display
parameters). After approx. 60 seconds the display jumps back
to the actual value. If the„P“ button is pressed for approx. 3
seconds, you get to the parameter list ("P10" is shown on the
display). Holding the„P“ button down for another 3 seconds
will display "C" for degrees Celsius (°C) or "F" for degrees Fah-
renheit (°F). If the„P“ button is pressed longer, the device type,
software version and build state are displayed. By pressing„ “
and„ “ simultaneously for approx. 3 seconds, you can access
the structure switch list via the parameter list.
Call up and change parameters
In order to reach the parameter list, „P“ must be pressed for
approx. 3 seconds until“P10” appears on the display.

Protection against unauthorized operation
In principle, the control setpoints can be set freely, provided
they are not limited by "P13/P14" or "P23/P24". All other para-
meters are protected by a code.
If a code is required, the display shows "C00". The required
code number "C42" is set with the arrow keys„ / “ and
conrmed with„P“.
After about 1 minute without pressing a button, the code is
requested again.
Autoscrolling
If you hold down the arrow keys„ / “ the values continue
to run automatically.
Factory reset
To restore the factory settings, you rst need to enter the code
"C42". To do this, any parameter simply has to be selected and
changed. After entering the code, the factory settings can be
restored by pressing all buttons simultaneously for approx. 5
seconds.

STRUCTURE SWITCHES AND THEIR MEANING
There are 9 structure switches (S01 to S09) with a dierent
number of switch positions. Each structure switch is assigned
a function with at least two or more alternatives, which are
selected using only one possible switch position per structure
switch.

RAMP MODE
Ramp start
Press button„ “ for >5 seconds, LED„2“ lights up continuous-
ly.
If the actual value is below the value stored for P50 (= start
value), this value (P50) is initially heated up (in two-point con-
trol). After reaching the start value, the stored ramp function
(P51 to P68) is started.
If the actual value is abovw the start value stored for P50, the
stored ramp function starts immediately.
After reaching the lsat stored ram value, LED "2" goes out and
the set temperature setpoint "P10" is approached (in two-po-
int control) and maintained permanently.
Pause
Press button„ “ for >5 seconds, LED„2“ ashes at a regular
rate. Current temperature is maintained permanently. By pres-
sing the button„ “ again for >5 seconds the ramp continues.
Abort the ramp in a controlled manner
Press button„ “ and„ “ simultaneously for >5 seconds, LED
„2“ ashes alternately long / short. Starting from the current
temperature, the ramp is ramped down with the next smaller
ramp value. After reaching the smallest ramp value, LED "2"
goes out. The set temperature setpoint "P10" is then appro-
ached and maintained permanently.
Cancel ram immediately
Press button„ “ and„ “ simultaneously for >5 seconds, LED
„2“ ashes alternately long / short. Press button„ “ and„ “
simultaneously again for >5 seconds, LED„2“ goes out.
The ramp function is now inactive, the set temperature setpo-
int "P10" is then approached and maintained permanently.
Ramp mode 2-point
The actual value x is recorded via a temperature sensor or a
standard signal and converted into a digital signal.
Before this signal is sent to the controller, the actual value is
corrected. The corrected actual value is shown on the display.
The setpoints w1 to w9 and the associated running times t1
to t9 are set on the controller. The current ramp phase, the
current setpoint and the remaining run time of the ramp
section can be shown on the display.
