Operation and control
Mechanical temperature monitoring: Temperature limiter (TB)
The appliance is equipped with a mechanical temperature
limiter (TB) of protection class 1 in accordance with DIN 12 880. If
the electronic monitoring unit fails during operation and the
default maximum temperature is exceeded by at least 20 °C, the
temperature limiter, as the final protective measure, switches off
the heating permanently.
Adjusting temperature monitoring
1. Press the activation key to the left of the
ALARM display. The temperature moni-
