Markel 43560001 Control 318820-201 Utilizing an injection kit forThe 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
