A power supply circuit for an electronic thermostat includes a half wave rectifier, at least one voltage dropping resistor and a gated rectifier. The gated rectifier preferably conducts only when the voltage at its output drops below the voltage at its gate. The voltage at the gate is defined by gating circuitry downstream of the voltage dropping resistors. The intermittent conduction of the silicon controlled rectifier produces less current flow through voltage dropping resistors within the power supply circuit. This causes less heat dissipation by these resistors within the thermostat.
