3. Operating modes
The temperature switch has the following operating
modes:
n Run mode (normal working operations)
n Display mode (display of set parameters such as
switching points, opener, closer...)
n Programme mode (setting of parameters such as
switching points, opener, closer...)
n Reset mode (resetting to standard values)
Switching on
When the supply voltage is switched on, the temperature
switch carries out a self-test.
n The display and the switching point indication light up.
n 150°C is displayed.
During this time (2secs.) the outputs are not active.
Run mode
After switching on, the temperature switch is in run mode.
The digital display indicates the actual system temperature
and the two yellow LED´s signal the actual switch status of
the outputs. It carries out its monitoring functions, switches
the switch outputs in accordance with the set parameters
and converts the actual system temperature into an
analogue signal.
Display mode
In the display mode the control parameters can be shown
but cannot be changed.
To ensure trouble-free operation, the temperature
switch remains internally in the run mode. If no key
has been pressed for 30 seconds, the temperature
switch changes back automatically to run mode.
Display mode activation is by the Enter key .
The letters diSP appear.
n A short touch on an arrow key or scrolls
through the menu points.
n A short touch on the Enter key shows the relevant
parameters.
D A password is shown as ----.

Programming mode
In the programming mode the parameters are changed
and stored thereafter continuously. An electrical supply is
not necessary for the retention of stored data (storage in
EEProm).
To ensure trouble-free operation, the temperature
switch remains internally in the run mode. If no key
has been pressed for 30 seconds, the pressure
switch changes back automatically to run mode.
Activation of the programming mode
To exclude the unintentional change of programmed
parameters, the programming mode can be activated only
by the following key combinations:
n Press an arrow key or and keep it depressed.
Whilst holding an arrow key depressed, press the
Enter key .
The letters
ProG appear.
Password protection
To prevent any unauthorised change of parameters, the
programming mode can be protected by an optional pass-
word.
n When a password has been programmed in, PAS
appears. With the arrow key
or the password is
entered and confirmed with Enter
. After this the
pressure switch can be programmed.
n If no password has been set up (password= 0000),
the pressure switch can be immediately programmes.
Programming
n Press an arrow key or to scroll through the
menu points.
n Pressing Enter shows the relevant parameters.
n Pressing the arrow keys or changes the
selected parameters. Holding the arrow key
depressed achieves fast and easy input and the
values of the parameters to be set can be changed
faster.
n· A changed value is confirmed with the Enter key
and the next menu point is then displayed.
The temperature switch carries on with its
monitoring functions to the existing parameters
until the respective change is concluded.
Reset
When the supply voltage is switched on the two arrow
keys
are pressed simultaneously.
At this point
rSt appears.
When both arrow keys and are kept depressed
and the Enter key
activated, the pressure switch resets all
the settable parameters back to the factory settings.
