Siemens Building Technology QAA2212.FWNN Sensor 320735-701 Advanced Flame Sensing: Continuous microamp

Advanced Flame Sensing: Continuous microamp monitoring prevents gas buildup by ensuring immediate shutdown if the flame signal is lost

Fail-Safe Reliability: The mechanical spring return mechanism ensures the valve returns to its normally closed position upon loss of power

with a fail-safe position timing of less than 60 seconds

Key Benefits Direct OEM Compatibility: Serves as the factory-spec direct replacement for 622656 and 1006724R

the 024-34916-000 is the designated replacement for that obsolete part
