Overview The SmartValve® System Controls combine gas flow control and electronic direct main burner ignition sequencing functions into a single unit. The ignition source is 120V hot surface igniter lighting the main burner flame. Provides all gas ignition safety functions by controlling gas flow, ignition source, and a 120 Vac combustion air blower. The control also monitors the appliance airflow proving switch circuit and limit string to assure proper appliance operation. The SmartValve...

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...

OverviewRemote bulb thermostats regulate temperature of air or liquids in ducts, pipes, tanks and boilers.FeaturesSuitable for applications requiring temperature control of air or liquids where controller must be placed outside the sensing area.Typical uses include control of dampers and valves in heating, cooling and heating-cooling systems.Fast response models (available for use in return air duct) operate approximately four times faster than standard models.Controller can be mounted in any...
