Abstract:
1. A signal conditioner for use with a controller and a burner, said signal conditioner comprising: a signal input electrically connectable to the controller for receiving a input signal from the controller; a signal output electrically connectable to the burner for sending an output signal to the burner; a conversion circuit electrically connected to said signal input and said signal output for generating a primary output signal corresponding to the input signal as the output signal; and a delay circuit electrically connected to said conversion circuit and said signal output for overriding the primary output signal generated by said conversion circuit and generating a delay signal at a predetermined level for a predetermined period of time as the output signal; the output signal is variable between a low limit and a high limit; said delay circuit is configurable such that the predetermined level is settable at either the low limit or the high limit.
