We have a model 13026W with indoor/outdoor temp (Alarm clock). All winter it was fine and seemed to be accurate. Now that the temp is near the 80's the outdoor temp seems to be accurate but the indoor temp is very high and is four to five degrees higher than our digital thermostat. Is there any way to re calibrate this unit? We have placed it all over the house and it is higher than than the actual ambient temperature measured in these spots. We do not have it placed near any windows or heat.

Hi CG Blade,

The following steps should help to resolve any issues you have been experiencing with 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. Locate the A-B-C ID switch inside each battery compartment. Make sure that the two parts are set to the same position. Please change both parts to the next available letter on the ID switch, as this can help to reset the unit. (Inside the battery compartment, you will see a small, white sticker with a 4-digit number. Please let us know this number.)


 


 


4. 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.)


 


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


 


6. 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.)


 


7. After a connection has been established, the sensor can be placed outdoors.


 


Please let us know if these steps were successful, or if we can offer any further assistance, have a great day!

This was no help. I stated that the outdoor temp reading was fine. I changed the batteries and they are fine. The problem is with the indoor temperature and always has been. Very sad to see you sent me a canned response instead of reading and analyzing the actual problem.

Hi CG Blade,

We are sorry that the above steps did not resolve the problem.  If your indoor temperature is still reading incorrect, we would recommend pressing and releasing the pinhole reset button, located in the battery compartment of the clock.  This will return your clock to the factory settings and should correct the inaccurate temperature readings that you are experiencing.  You will also want to ensure that you are using high quality, standard alkaline batteries, such as Rayovac or Energizer, in the clock.  We do not recommend anything that is heavy duty, rechargeable, generic or Lithium in the clock. 

After doing the factory reset, please allow the clock to sit in a shaded area in your home for 60 minutes to acclimate to the room temperature.  If it is still not reading correctly, please contact AcuRite Customer Support at 877-221-1252 to inquire about possible warranty coverage.  Have a great day!

I also have this problem with a new 02086 Weather Station bought from Costco. Actually the indoor temperature never changes. The outdoor works fine. I have reset and done all the steps above. Basically the indoor temp does not work, Steve

Hello Steve,

Please press and hold the reset button for 10-12 seconds.  This will factory reset the display.  Please let us know if the issue continues after you set up the unit again.  Thank you and have a great day!
