Abstract

A temperature control apparatus for the disclosed object, comprising a temperature responsive bridge connected between an oscillator and an amplifier that is connected via a phase sensing network to an output stage that controls three or more steps cooling and/or heating system, said network being connected to said amplifier by means of a transformer and intended to provide three or more control signals that differ in potential and, in relation to one or more of said phase signals.
