Controller additionally indicates whether it activates the feeder, the fan or the heater.
The heater activation and operation are indicated by means of a
horizontal

sign segment, on the Controller main display screen
(

)
.
If the sensor detects fire during firing up (sensitivity drops below the value indicated in the
F39 service
setting
