Okay i ordered this item a few weeks ago and i love it, now i do agree that the issue with the freeze warning is annoying, whenever the item comes down to 37 degrees F it will beep, but if you do the simple thing that i will describe it will not do that.
Okay this item has three channels, only the first channel sets off the alarm. so if you put the switch on the outdoor unit to channel 2 or 3 then press the reset button, then tell the recieving unit that it will be looking for something on channel 2 or 3 (press and hold channel and Memory). this will take care of it.
now about the batteries, yes if your outdoor unit will be in temperatures under -4 degrees you will need lithium ion batteries, if you go to the store a pack of four (you only need two for the outdoor unit) costs about 2 dollars more than a regular batteries and they last longer and go last all the way down till -40 degrees.
Atomic clock, mine would not connect at first, so i walked outside and told it to search again, then after about a minute it found it and i brought it inside and it works great.
Enjoy the product, i love it

I needed a replacement for my old-fashioned mercury style outdoor thermometer after it got broken. I thought it would be cool to have a digital thermometer that would warn me when the temperature dropped down below 15 degrees F, so I could leave faucets running to avoid frozen pipes. So, I bought this thermometer. The first one I got was defective (it read 5 F too high) and I returned it. The second one was accurate, but I noticed that it is relatively slow to respond to rapid temperature changes compared to a conventional style mercury thermometer.

What I like about it: The style is simple and elegant, the diplay is easy to read at a distance, the clock sets itself quickly and accurately, and the reception from the remote unit is reliable.

Now for the bad part. Whoever designed the temperature warning features should be fired! A loud beeping alarm will go off anytime the remote temperature unit senses a temperature from 28 F to 37 F, and there is no way to turn this alarm function off! I tried setting the high and low temperature alarms to see if that would override the default and it does not. This renders the unit useless as a temperature warning device! Dumb!

I decided to keep it anyway - just as a mere thermometer without any alarms. Here is how to do it: There is no need to take anything apart or cut any wires. You just have to open up the remote unit and move the small switch to channel 2 or 3 and press the reset button with the end of a paper clip. This is because the default channel 1 is the channel that sets off the alarms.

This is in most respects a nice unit. It's pleasant enough to look at and the numerals are legible. The radio-corrected time is a nice feature. But you should be aware of two issues: (1) The remote unit is battery powered and alkaline batteries freeze. You will have to use rather expensive lithium batteries in the remote unit during the months in which you have freezing temperatures. (2) The main unit warns you about this issue by beeping whenever the temperature goes into the range of 37-28 degrees F. If the main unit is in a sleeping area this will drive you crazy. There is no way to stop this except to open it up and cut the wire to the speaker. This disables the alarm for all purposes, but that didn't matter to me.

Not much to say, other than it worked right out of the box and it looks good and solid. The Atomic Clock self-setting didn't seem to produce an accurate time, even when I left it searching for a while, but I've never had luck with that feature on any brand device at my home, so I think it's my house and not the device.

The Oregon Scientific weather instrument is a nice item.As a 69 yr.old I found the writing to be too small.It was also difficult for me to set the alarm for weather changes even though I thought I was following the directions carefully.The weather alarm keeps going off at 37.4 degrees and I can't stop it.Maybe something ws left out of the directions.Thanks,Lloyd Julian

This unit looks like a winner. It's seems to be heavy duty enough. The indoor temperature and the atomic clock are accurate, but the outdoor temperature is 10 degrees high...even at night.

I guess I'll have to return it. The return process was fast and easy.

This product works great and as advertised, and is very accurate compared to a borrowed $500.00 weather station. There are 3 channels for the wireless, select channel 2 or 3 for the non-freeze alarm channel. THOSE WHO HAVE COMPLAINED ABOUT THIS CAN'T READ INSTRUCTIONS. And, get lithium batteries for freezing conditions. All alkaline batteries freeze at about 10 degrees, and won't work. Any brand of wireless temperature sensors need lithium batteries for freezing conditions. AGAIN, THOSE WHO HAVE COMPLAINED ABOUT THIS CAN'T READ INSTRUCTIONS.

This is a nice little unit with remote temperature sensor. My only complaint is that the remote reading can be off by up to 2.5 degrees (high or low). Oregon Scientific says that's within their margin of error, but I don't think a 5 degree swing is acceptable with modern equipment. If you can live with that amount of imprecision in the temperature read-out, this unit is fine; otherwise, look elsewhere. Although I don't know for sure, other Oregon Scientific equipment might similarly be inaccurate. A little tricky to set up, but the instructions are clear enough.
