The board supports both 24VAC and 115VAC intercepted calls

Optimized Conductivity: Designed to carry the full secondary voltage pulse required for consistent arc generation in the combustion chamber

Can this electrode be used in other Vitodens models

Can I use this to replace an older LME69

The visible set point indicator and internal adjustment screw simplify field configuration and performance verification

Markel 29157004 Limit R-410A The board supports both 24VACThe Markel 29157004 Limit is a mission critical high limit safety switch designed for precision thermal protection in HVACR systems. Specifically engineered for duct heaters and electric heat assemblies, this manual reset limit prevents catastrophic equipment failure by breaking the electrical circuit when internal plenum temperatures exceed safe thresholds. Identified by the technical designation MFHE LIMIT RD103 002 104C, this component triggers at
