6.6.3 Temperature Selector Limiter (TWB)
i
In programme mode, the current programme is resumed for TWB alarms of up to 15
minutes. If the alarm is active for more than 15 minutes, the programme is cancelled.
6.6.4 Automatic Temperature Monitor (ASF)
ASF is a monitoring device that automatically follows the set temperature setpoint within
an adjustable tolerance band.
The ASF – if switched on – is automatically activated as soon as the actual temperature
value reaches 50% of the set tolerance band of the setpoint for the first time (sectionA).
When the temperature leaves the set tolerance band around the setpoint – e.g. if the door
is opened during operation (section B) – the alarm is triggered. The ASF alarm is
automatically deactivated as soon as 50% of the set tolerance band of the setpoint has
been reached again (sectionC).
If the temperature setpoint is altered, the ASF is automatically disabled temporarily
(section D), until it is once again within the tolerance range of the new temperature
setpoint (sectionE).
6.6.5 Mechanical Temperature Monitoring: Temperature Limiter (TB)
The appliance is equipped with a mechanical temperature limiter (TB) of protection class1
in accordance with DIN12880.
If the electronic monitoring unit fails during operation and the factory-set maximum
temperature is exceeded by approx. 20°C, the temperature limiter, as the final protective
measure, switches off the heating permanently.
