Fenwal 05-129608-922 Cable 321702-401 Flexible Application: The SPDT switch

Flexible Application: The SPDT switch action allows for use in both cooling-only and heat/cool configurations with an external changeover switch

reducing potential failure points in high-vibration environments

Use only with the fuel type specified on the unit's nameplate

it includes an adjustable mechanical backup that will terminate the cycle if the sensor does not activate within the set timeframe

it is standard practice to inspect the thermocouple separately during maintenance to ensure a proper millivolt signal

Fenwal 05-129608-922 Cable 321702-401 Flexible Application: The SPDT switchThe Fenwal 05 129608 922 is a high performance 7mm suppression cable designed for critical ignition sequencing in HVACR heating systems and industrial thermal processing. This ignition wire assembly features high dielectric insulation to prevent voltage leakage and electromagnetic interference (EMI) during the spark cycle. Engineered to withstand the thermal cycling common in burner compartments, this Fenwal ignition cable ensures consistent signal
