A compromised retainer often manifests as increased mechanical vibration

allowing for rapid field replacement and streamlined wiring

such as a boiler or gas manifold

protecting the evaporator coil and fan motor assembly from premature wear caused by debris or bypass air

Standard wiring involves 24V hot (Term 1)

Markel 43560001 Control 324846-701 A compromised retainer often manifestsThe Markel 43560001 Control is a heavy duty, factory specified Fan Delay Purge Control designed specifically for the 3480 and RCH Series commercial recessed ceiling heaters. Engineered with an L115 20F thermal switch, this component manages the critical purge cycle by delaying fan deactivation after the heating element cycles off. This thermal management ensures that residual heat is fully dissipated from the element, protecting the internal
