How does this pilot assembly improve system efficiency

maintaining the integrity of the original electrical sequence and improving the overall efficiency of the heating and cooling cycles

it requires a complete changeover to POE lubricant (typically targeting <5% residual mineral oil) to ensure proper oil return and compressor longevity

Designed to bridge the connection between the flame sensor probe and the control module (IFB)

This specific model is a standing pilot assembly but features an optional spark electrode port for systems requiring manual or piezo-assisted ignition
