This HVAC control relay is essential for maintaining the sequence of operation in air handlers and furnaces

minimizing pressure drop across the line—critical for maintaining system efficiency in HVACR refrigeration shutoff applications

this 3-ton capacity valve ensures restored system equilibrium and peak energy efficiency after a restricted or stuck expansion valve is identified during diagnostic manifold gauge readings

Its normally closed (NC) design is a critical fail-safe in air handler repair and heating system maintenance

Fenwal 35-655802-007 Ignition Control Els PW 17895 This HVAC control relay isThe Fenwal 35 655802 007 is a high performance 24V Hot Surface Ignition (HSI) Control engineered for precise burner management in gas fired appliances. This microprocessor based module features a 15 second Trial for Ignition (TFI) and is designed to replace aging 05 21, 05 24, and 05 32 series controls. For field versatility, it supports 120 240V field selectable line voltage for the ignitor while maintaining a standard 24VAC control circuit. Service
