The Q3450 or Q3480 Pilot hardware supplies the low voltage igniter, flame sensor and pilot burner. These ignition system controls provide all gas ignition safety functions by controlling gas flow, ignition source, and a 120 Vac or 240 Vac combustion air blower. The controls also monitor the appliance airflow proving switch and limit string to assure proper appliance operation, and provide prepurge, postpurge, and timed trial for pilot ignition with 100 percent shutoff and continuous retry. A diagnostic LED indicates system status.\u003cbr\u003e\u003cbr\u003eProduct Features:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eThese controls communicate directly with an electronic fan timer (ST9160 Electronic Fan Timer for single stage applications; ST9162 Electronic Fan Timer for two-stage applications) in typical forced warm air furnace applications\u003c\/li\u003e\n\u003cli\u003eThey also interface with the 208907 Terminal Board, providing compatibility with power stealing thermostats.
