How To Identify the Hardware Version (1st or 2nd Generation) of Your Harmony One.
There are typically three numbers that are used to identify a particular Harmony Remote model. They are:
• P/N = part number
• M/N = model number
• PID (or S/N) = product ID or Serial Number
On the Harmony One the P/N, M/N and PID (or S/N) are located on a label that is visible when the battery
door cover is removed. A sample P/N is 815-000037, a sample M/N is R-IY17, and a sample PID number is
WD751XM. S/N’s replace the PID in some cases and a sample S/N looks like this: 1151WD01E778.
To determine the version of the hardware board requires only looking at the PID or S/N number. Note that
you will see only one of these listed, either a PID or S/N and there will never be both. These numbers are not
unique and actually represent manufacturing lot numbers. Thousands of Harmony controllers have the same
number. So, here’s what you need to know:
• Any PID that starts with LZ represents a 1st generation hardware board. (ex. LZ544B700CG). If you have a broken LCD, you will need to order the Logic Board Replacement Service.
• Any PID that is formatted like WDnnnXM, where nnn is a number between 600 and 999, represents a unit
that is 1st generation. (ex. WD840XM). If you have a broken LCD, you will need to order the Logic Board Replacement Service.
• Any PID that is formatted like WDnnnXM, where nnn is a number between 004 and 100, represents a unit
that is 2nd generation. (ex. WD036XM). If you have a broken LCD, you can order the LCD Replacement Service or you can order the LCD for DIY.
• Any Harmony One that has an S/N that starts with the number 1 represents a unit that is 2nd generation.
(ex. 1151WD01E778). If you have a broken LCD, you can order the LCD Replacement Service or you can order the LCD for DIY.
If there is a sticker that has been placed on top of the original label and the number starts with LV (ex.
LV837RF), this indicates a refurbished model and the sticker must be peeled up to expose the original PID
number below it. The original number will determine the version of the hardware board.
Note that the PID or S/N on the charging cradle cannot be used in lieu of the number on the Harmony One.
These numbers are often not the same.
Any PID numbers that are found out of the ranges above may be ‘cusps’, in that the board could be either 1st
or 2nd generation, or the remote may have been manufactured for a different region, (Europe for example). In
some cases, the label is missing altogether. If your Harmony One falls into any of these categories, the remote
must be opened in order to confirm the board version. Watch this video to see how to open the Harmony One without damaging it.
