SV9570 SmartValve Water Heater Controls

The SV9570 TRADELINE® 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. Two types of 120V igniters may be used. SV9570 Controls provide high temperature thermal cutout 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 SmartValveTM Water Heater Control provides pre-purge, postpurge and timed trial for ignition with multiple ignition trials and auto reset from lockout. Diagnostic LED indicates system status.
