This works for a whirlpool ND50T122-403 water heater. Plug in, reset the sensor lockout (turn heat control up them down twice) and she fires right up! Honeywell controller. Numbers stamped on the sensor are 7203 160778 T-O-D 25VS

Works perfect with White Rogers, intellivent controller, this was installed on an AO Smith 2 series hot water tank.

It worked perfectly for my Richmond Power Vent Water Heater.<br />Resetting the FVS lockout was a bit of challenge but the internet helped.

Product as described.

OMG! Had a pair of Beats wireless that I lost [or was stolen] Wanted a replacement but now I was gun shy about spending another $220+. So I elected to try this headset based on some positive reviews. WOW! where do I begin. First off, unlike the Beats headset the controls on the earpieces are easy to manage. Even with gloves on. I mow the lawn with these on and I can tell you the ANC beats the Beats headset by miles. A button on the bottom of one of the earpieces silences the music and ANC. pressing it while I was mowing and I almost thought I was at the end of a runway. Proves the ANC is great. Earpieces are also more comfortable than the beats. Little things that might seem stupid are thought of. OK, who needs a L and a R on the inside of the headset? I do! I can tell you how many times I put the Beats on backward only to punch the wrong button on the headset because I had them on wrong. I love the way that they mute when you remove them from your head only to start again when you put them on. Range is as good or better than the Beats. At least 100 ft. Also, a frustrating thing about the beats is that it would only connect to one bluetooth at a time. So, if I was using my Iphone and wanted to use my IPad, I had to disconnect my IPhone and turn off the bluetooth to connect to IPad. This headset connects to multiple sources. No need for switching.

Solved the vapor sensor problem described here by many other reviewers.<br /><br />Just want to add that this works with Honeywell control unit.
