The 265/277v units will not work in a 208/230v hotel without a transformer. Basically you do not want to get involved with that. When replacing your PTACs stick with the proper voltage. As far as a conversion kit, if one exists, the cost will put you right back at the cost of a new unit. If your hotel is wired for 208/230v it won't give the unit the power it needs to function properly. When looking for replacement units here's what you need to match (besides getting the proper BTUs):
Voltage
Unit size (make sure they fit in your existing sleeves)
Power cord configuration (the 265/277v will have a different power plug)
Good Luck!

My amana ptac is not heating....the code "np" is displayed....how do I correct this...we just installed the unit and know little about operation. Thanks


I don't see this error code in the manual. I do see nP as an error code for Window Switch lockout. I just had this happen to me and they had me reset the control board.

Remove case, flick master switch to OFF for 10 seconds. Press Heat/Cool same time turn switch back on HOLD until off light comes on.

You should be fixed. Just had to do this for my unit. I was playing around with the settings and turned on the window switch option by accident.

My 7yr old Amana PTAC unit, Model PTH123B50AJ sometimes works and sometimes not. I had a repair tech check it & he told me the control board was bad and they wanted $440 to fix it. I told him no,


EBay often has the control boards for Amana heat pumps, and installing them is fairly straightforward, provided you have some experience with electronics, a soldering iron, etc. Amanapartsonline.com may also be able to sell you the part, which should run between $50 and $150.

Given, however, that the thermostat is also showing problems, as well as what parts are going for these days, I'd seriously consider upgrading to a new unit and selling the old one on Craigslist to offset the cost a bit. If you can find an HVAC technician, someone who's learning HVAC, someone who just wants it for a guestroom where it need not work perfectly or a landlord who can afford to have a secondhand unit fixed and put it in one of their properties for their tenants to buy your fixable old one for a few hundred dollars and a new one only runs about $700, your upgrade will cost less than having the 7-year-old unit repaired, plus you'll be recycling.

LP126HD3A rated for 265 volts AC single phase I have 240V ac single phase, how can I use this unit on 240V ac


You'd need to supply a "Buck-Boost" transformer to do this properly. Technically, the 265 VAC is one hot leg and neutral of a 480 VAC 3 Phase Y system that measures 277 VAC. The 265 number comes from this:

265 is the standard nameplate voltage for a 277 volt motor or AC unit.

230 is standard name plate for 240.
200 is standard name plate for 208
460 is standard name plate for 480.
110 is standard name plate for 120.

Most electricians call the hot leg / neutral circuit "277V AC".

Some popular "Buck-Boost" transformers will convert 208 to 240 and 240 to 208 volt systems, and 240 to 277 and 277 to 240 volt systems - among many other variations. These are auto-transformers as the primary secondary windings share a connection. KVA ratings differ significantly from name plate because of this fact. You should contact a qualified electrician to not only size, but wire the transformer for you. Failure to install a Buck-Boost transformer - and running this unit on 240V AC mains will cause premature failure of motors - fans and compressor due to overheating. This can also result in a fire hazard.

I hope this helps and good luck!

You can actually google PTAC units or window a/c units and a whole bunch of stuff will come up.Some of the things that will appear are foroms where people give their own opinions/reviews of the one they purchased and have used for a couple of months or so.Some people will say don't ever buy this,etc. etc.They also have a rating system that averages out everyone's ratings.

this solution would likely work fine if you were only looking to have 110vac power. In order to have 220vac from two 110vac devices, you would need expensive equipment, and technical knowledge.

What you need to do in order to get 220vac is buy an inverter that will provide 220vac. There are many available.

Hope that helps.... Good Luck!
