Our oven (all it says on it is "Electra" - I believe it is a European model) has two knobs - one for cook setting and one for temperature.
The settings knob has four settings - the first two are obviously for bake and broil:
The other two settings have me stumped - one is the letter "P
" and the other is the Greek or Cyrillic letter Psi (Ѱ
Anyone have any clue what these two settings are for?
