
Standard indication (setting value below, actual value above (see photo)) must to be seen.

Press both together, key PGM and

for 5 seconds,
Indication = Code 3 (all levels are locked)

Press PGM

Change the value from 3 to 2 by using the key


The display flashes after approx. 2 seconds and the alteration is taken over.

The user level is now cleared.

Press EXIT .
In order to go forward to the user level now, press key PGM, Indication = User

Press the key PGM once again, indication = SP (setting value, adjustment at works 350 or 680
depending on converter cartridge)

Press key

, indication = ALSE (temperature range for sensor and heating control, adjust-
ment at works

10)

Press

, indication = Lo-t (relative temperature to temperature setting value for low tempera-
ture alarm, adjustment at works -10)

Press

, indication = rASL (ramp gradient, temperature increase in °C/min, adjustment at
works 30)
In order to change one of these parameters, you must press the PGM key again after SP, ALSE,
Lo-t or rASL are to be read on the display. The respective value is flashing now on the display and
can be modified by using the keys

or

.
The automatic taking over of the setting value is made after approx. 2 seconds; this is indicated by a

tion, the standard indication is shown.
In order to switch on again the key locking, change the code to 3 again as described above.
N O T E !
If you reduce the setting value by more than 10°C, the sensor control will be
released and the heating circle switched off. For the reset, wait until the
value remains under the new setting value, switch off the mains voltage
and switch it on again.
18.4 RESET OF THE CONTROLLER
A reset out of the temperature lock happens with connected mains:

operating simultaneously the keys EXIT and

A reset only happens in case the actual temperature deviates by < +/- 10°C from the theoretical tem-
perature.
