摘要： The present invention is a method and apparatus for preventing a decision made by a controller from being made based on incomplete information where the controller periodically runs a decision making routine. The controller makes decisions based on a plurality of AC input signals being present or absent. The presence or absence of the AC input signals is read by the controller during a read cycle performed during periodic half cycles of the AC system signal. The AC system signal and the AC input signals are substantially phase-synchronizes. Before the controller runs the decision making routine, the controller determines whether the presence or absence of the AC input signals has changed since the previous decision making routine. Where the presence or absence of the AC input signals has changed since the previous decision making routine, the decision making routine is delayed for a predetermined number of half cycles of the AC system signal.

摘要： The present invention is a method and apparatus for monitoring a plurality of AC input signals to a control system. An AC interrupt signal is generated, based on an AC system signal which is substantially phase-synchronous with the AC input signals, for an interrupt time period corresponding to a time period when the AC system signal exceeds a predetermined threshold voltage. The AC interrupt signal is verified and a timer is set for a pseudo-random time value. The AC input signals are sampled when the timer has reached the pseudo-random time value to determine the presence or absence of valid AC input signals.

摘要： Damper position of a damper in a heating system is monitored. The damper is movable between end positions in response to movement of a motor shaft. The motor shaft moves in response to a movement request signal. A shaft position signal is received by a position detector and has a value representative of position of the motor shaft. When the damper reaches an end position, it is determined whether the value of the shaft position signal is within a predetermined tolerance. If it is outside of the tolerance, then the system is shut down as unreliable; otherwise, the shaft position signal is recalibrated to maintain accuracy.

摘要： A control logic means or microcomputer controlled burner control system has been disclosed. The system utilizes a safety relay that has contacts that are in series with all of the other loads for the system. The safety relay contacts are checked prior to operation of the system to verify their ability to open the load circuit. The operation of the electronics for the control of the safety relay are regularly checked during the operation of the system by a combination of feedback circuits from the electronics, and from the final control element for the various loads.
