Remotec ZXT-120US IR extender and Frigidaire A/C unit

[casm]

We have a window-mounted Frigidaire A/C unit that came with an IR remote (manufacturer model no. RG15E/E-ELL; may also be compatible with RG15E/E-ELL1). We're trying to control it with a Remotec ZXT-120US IR extender, but are having zero luck with getting it working.

The ZXT-120 seems to be working, at least as far as Domoticz and OpenZWave are concerned. Here's what's been tried / verified so far:

• ZXT-120 is running on USB power, not batteries, and is configured in 'Always Listening' mode
• Have tried all codes for Frigidaire as well as related manufacturers (Electrolux, General, Gibson, Kelvinator, Westinghouse, White-Westinghouse)
• Can see the red activity LED on the ZXT-120 blinking when sending commands to it via OpenZWave
• Can see the IR LEDs fire when sending commands via OpenZWave (used phone camera to confirm)
• Manufacturer's remote controls the A/C unit without issue, so the IR receiver in the A/C unit is presumed working
• Tried with A/C unit already on in case the ZXT-120 wasn't waking it from being off; no luck

The one thing I unfortunately can't do is pull the model number of the A/C unit. It's on a label on the side of the unit, and in order to read it I'd have to unbolt the unit from its wall supports two storeys above ground. Don't have a ladder that can reach that high.

Has anyone else run into this issue? I realise that learning mode may be my only option, but would prefer to not go that route if possible. The RG15E/E-ELL remote seems to be fairly common unit, so I'm hoping that someone with an A/C unit that also uses this remote has been here before and can advise.

Understood, but I'd like to see if what I have can't be made to work before buying other hardware.

In any event, does anyone with experience with the ZXT-120 have recommendations for how to proceed? By all accounts it should be working but isn't.
