the ASCO 8210G34 typically requires a minimum operating pressure differential (often 5 PSI) to functionally open or close the diaphragm

guaranteeing the correct BTU throughput

This board serves as the direct replacement for legacy part numbers 031-01222-000

meaning the switch closes automatically once the sensing element warms up by the fixed 12-degree differential

Laars Heating Systems R0408100 Module 323080-701 the ASCO 8210G34 typically requiresThe Laars Heating Systems R0408100 Module is a critical 24V direct spark ignition control engineered for high performance gas fired boilers and pool heaters. This digital heater ignition control is a direct replacement for Teledyne Laars and Jandy units, specifically designed to manage the combustion sequence in Lite2 LD, LX, and LT Series heaters. Operating on a 24VAC circuit, the module features a 15 second pre purge (15sPP) cycle to clear residual
