Honeywell SV9570A2526 Direct Hot Surface Ignition SmartValve Control
The SmartValve™ Water Heater Control System is a single unit which combines direct ignition sequencing, gas flow control, temperature sensing and setpoint adjustment features. These controls were designed specifically for gas fired, forced-draft hot water tank heating applications. The ignition source is a 120V hot surface igniter lighting the main burner flame.
Features
• Controls provide high temperature thermal cut-out and all gas ignition safety functions, controlling gas flow, ignition source, water temperature and a 120 Vac combustion air blower.
• The control also monitors the appliance airflow proving switch and limit string to assure proper appliance operation.
• The SmartValve Water Heater Control provides prepurge, postpurge and timed trial for ignition with multiple ignition trials and auto reset from lockout.
• Diagnostic LED indicates system status.
