Honeywell Super Tradeline SV9641M 4510 Intermittent Hot Surface Pilot Ignition SmartValve Control New item. In original box. 3/4" NPT x 3/4" NPT Intermittent Hot Surface Pilot Ignition SmartValve Control with standard opening and 3.5" wc pressure regulator setting Includes: (2) 3/4" x 1/2" reducer bushings and an LP conversion kit. 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. They also interface with the 208907 Terminal Board, providing compatibility with power stealing thermostats. Or, they 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 SV9541 and SV9641 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.
