Power board(shown upside down)

Transformer power supply5 relays (10 Amps each) to control the individual heating elements2 APD* relays (16 Amps each) for safety all-pole disconnectOverheat protection NTC on power board: can cut off heating elements (Alarm Er21)It is also possible that power is reduced temporarily without showing this to the user !

*APD = All-Pole Disconnect
