Description

The Hayward FDXLFWP1930 is the genuine field wiring panel kit for the Universal H-Series Low NOx heaters. It covers the whole FD range, from the H150FD up to the H400FD.

What it is

The field wiring panel is where the wiring brought to the heater during installation lands. Hayward supplies it as a kit under a single part number rather than as loose pieces, and the same number is called out across all six heater sizes in the range.

Which heaters

H150FD, H200FD, H250FD, H300FD, H350FD and H400FD. Hayward also lists the kit for use with ASME heaters and with the pool and spa or hot tub versions of these models.

Not the control board

This is the wiring panel, not the control board. If the fault is in the heater logic rather than at the field connections, the control board kit is the separate part to look at.
