1. A thermostat for an aircraft heating system supplied with DC power from an onboard source, said thermostat comprising:

  • power-supplying circuitry including a source line adapted for connection to a supply line of the onboard DC power source, a high voltage line providing heating power, and a low voltage line providing operational power;

    processing circuitry receiving operational power from the low voltage line and formulating instructions relating to the heating power;

    heating circuitry controlling supply of the heating power from the high voltage line in accordance with the instructions formulated by the processing circuitry; and

    sensing circuitry conveying a sensed temperature to the processing circuitry for input when formulating the instructions relating to heating power;

    wherein the heating circuitry and/or the sensing circuitry also detect faults and report them to the processing circuitry.
