SmartValve™ System Controls
APPLICATION
The SV9410/SV9420; SV9510/SV9520;
SV9610/SV9620 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. Two types of 120V igniters may be
used; see Table 1. 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™ System Controls provide prepurge,
postpurge and timed trial for ignition with multiple
ignition trials and auto reset from lockout. Diagnostic
LED indicates system status.
The control communicates directly with the ST9160
Electronic Fan Timer (EFT) in typical forced warm air
furnace applications. It will also interface with the
208907 Terminal Board, providing compatibility with
power stealing thermostats. Or, it directly interfaces with
the appropriate power supplies and a system
thermostat for additional appliance applications. When
controlled directly by a thermostat, the control does not
provide a postpurge function, as power to the control is
removed when the thermostat call for heat ends.
This system is 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. The
specific application of the SmartValve System is the
responsibility of the appliance manufacturer. See Table
2 for temperature ranges and regulator types.
Line voltage polarity sensing models monitor the line
voltage input connection to assure line voltage polarity
is correct. If line voltage polarity is incorrect, the LED
diagnosis code will flash and the control will not
respond to the call for heat. These models also provide
added LED diagnostic codes (“6+”) to indicate the
reason the control has moved to the lockout state. See
Tables 9 and 10.
