I have a 522SBDI weather thermometer & the outside temperature is stuck on 27. The batteries were replaced in both outdoor sensor & display unit. The sensor's light is flashing as it suppose to & bars on the display unit show a good signal.

Hi, Dave:
Did the problem exist before you changed batteries?  Is that 27 Celsius or Fahrenheit?  The reason I ask is that 27 C = 81 F and Reno, right now, is in the mid 80's.

Hi David,

As Harold has suggested, we would recommend that you check the temperature scale to be sure it is set correctly. If this is not the issue, we would recommend a reset of your unit.

Before proceeding with the reset, please check your batteries. We recommend that the batteries meet the following criteria:

• Verify you are using standard alkaline batteries such as Rayovac or Energizer. Lithium batteries can be used in the outdoor sensor if you are in a location that will frequently see temperatures below -4oF/-20oC. (Rechargeable batteries, as well as batteries that indicate a heavy-duty quality are not recommended, and may cause irregularities.)
• Verify that you are using a fresh set of batteries. The battery expiration date should be at least 6 years out. Batteries can lose 3% of their power or more every year in storage.

1. Bring both the sensor and display unit indoors and position them side by side.

2. Remove all batteries from both the sensor and the display unit. (If the display has an AC adapter, please unplug this, as well, to completely power down the unit.)

3. Reinstall batteries in outdoor sensor first. (Please be sure that the red light on the front of the sensor blinks, as this will assure that the sensor is powered on.)

4. Reinstall batteries (and/or reconnect AC adapter) to the display last.

5. Let both sensor and display sit side by side to establish connection. (Leaving the devices side by side for 30 minutes will allow you to verify accuracy by comparing the indoor and outdoor readings shown on the display. For accuracy standards, please visit http://www.acurite.com/accuracy.)
6. After a connection has been established, the sensor can be placed outdoors.

I too have a 522 SB and it has been stuck on 27 degrees since the day I bought it.  I've taken all the steps described above
