EmersonThermostats F145-1378 RF1451378, 1.75

I purchased this to have my emerson thermostat show outdoor temp but it is grossly inaccurate. I spent a lot of time selecting a proper installation location so it would not be affected by sunlight or heat from equipment. Only to have it still not read correctly.

Displayed temps are 5 deg lower than actual when outdoor ambient temp is below 55-60 deg. I have only been through 2 seasons already, so who knows. Seems to be accurate when outdoor ambient temps are warmer.

These guys always deliver as promised. I've made many purchases from them and expectations are always met. Over time, I've had a few issues with items purchased (e.g warranty issue w/Honeywell T-stat). I typically deal with Joe and will tell you, they stand behind everything they sell without question. A comparable company is Costco... fair price+easy returns+stand behind the product sold= a satisfied customer that will always come back.

Very good accuracy. Easy to install with no adjustments needed works great on my modulated efficient Rheem furnace. A great but.

Worked as advertised with my stat. Three wire design and the control box seems a little big just for being a thermocouple.

As described.

This is a good idea; however the unit(s) I purchased was extremely unreliable. Once the temp reached 68 degrees it would stop working. I replaced it (3) time and each unit right out of the boxed did the same thing. I would not recommend this product.Clearly a very poor design

The best one I've purchased yet. It's been over 6 months and not a single issue. I was a little worried about the display at first but I now believe it to be first rate.
