ZERO CROSSING : The relay which powers the Tank’s electrical resistance is equipped with the “ zero crossing “
function which synchronizes the switching of this relay, both in closing and in opening, with the voltage supply’s
passing to zero both for 50 Hz and 60 Hz frequencies. In this manner the relay’s contacts usage is significantly
reduced.
