2.6 Heater (R1, R2) Safety Function
If the fill-ring NTC (1R30) is defective, the heater is not switched on.
If the heater is switched on, but the motor is not running for more than
5 seconds, then the heater is switched off.
Heater reactivation is delayed by 10 seconds.
The auxiliary heater is switched off before, during and after a reversing
pause.
2.7 Insufficient-Air Detection
The heater bank NTC (2R30) monitors the temperature increase in the heater
bank. If the air paths are clogged, the temperature in the heater bank rises
rapidly during heating. This is detected and the fault message “insufficient air”
is displayed. If the temperature at the heater bank NTC exceeds 338°F
(170°C), then fault code F66 (“leaking air”) is issued.
2.8 Dryer Function after a Power Interruption
Timed programs: After power is restored, the dryer continues automatically
at the point where the program was interrupted.
Residual-moisture programs: After power is restored, the residual moisture
is recalculated.
Power interruption during a cooling air or anti-crease phase: The
program does not continue. The program last selected is displayed again for
restart.
