Robertshaw's Universal Ignition Control Uni-Kits feature a flame sense circuit that will work equally well on a one rod (local sense) or a two rod (remote sense) application

The automatic recycle features assure that, in the event of flame failure, main gas is disabled and the spark repetition sequence is restarted until pilot gas is ignited. Only after pilot ignition has been re-established can main gas be returned to the burner.
