You must reuse your existing 24V coil or purchase a compatible ClimateMaster solenoid separately

allowing it to survive significant system spikes without damage to the sensing element

which is essential for rapid troubleshooting in the field

you can upgrade to a higher voltage rating like 440Vac as long as the capacitance (30/5 MFD) and physical dimensions match

While the 3/4-inch NPT thread is a common standard

Velocity Boiler Works (Crown) 400821 LWCO 326058-758 You must reuse your existingMaintain critical safety in steam systems with the Velocity Boiler Works 400821 LWCO. This Hydrolevel CycleGard CG 400 series control uses advanced conductance sensing technology to monitor water levels without the mechanical failure points found in traditional float style cut offs. As a veteran technician knows, surging and foaming in steam boilers can lead to false readings; this unit leverages Intermittent Level Test (ILT) logic to periodically
