exclamation mark blinks in the
bottom line until the next value
is entered and successfully

furnace head open (heating or
cooling). Once this temperature is
reached, pre-drying is carried out
during the „pre-drying holding
time“ Once the holding time has
elapsed, the furnace head is closed
within the desired closing time.
