Oh - the AAR and WUR don't send electrical signals to anything. They are valves, if you will, not sensors. The WUR does control the control pressure at the FD, but that is hydraulic. The thermo-time sensor does send a sort of signal - it either keeps a circuit closed (current flowing), or open - it is a switch, and keeps the CSV from flooding the engine.
