Abstract:
1. A thermostat for an aircraft heating system supplied with DC power from an onboard source, said thermostat comprising: power-supplying circuitry configured to receive, through a source supply line, DC power from an onboard DC power source, the power-supply circuitry configured to divide the source supply line into a high voltage supply line providing heating power and a low voltage supply 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.
