The SmartValve System Controls combine gas flow control and electronic intermittent pilot sequencing functions into a single unit. 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. Includes a diagnostic LED indicates system status.


Features:

  • These 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;
  • It can directly interface with the appropriate power supplies and a system thermostat for additional appliance applications;
  • When controlled directly by a thermostat, these controls do not provide a postpurge function, because power to the control is removed when the thermostat call for heat ends;
  • The Systems are suitable for a wide range of fan-assisted combustion gas-fired appliances including furnaces, rooftop furnaces, boilers, unit heaters, infrared heaters, water heaters and commercial cooking appliances.
