Have 75075w2 with indoor and outdoor temp... First noticed outdoor temp was "stuck" on 74... even though actual temps outside varied from 60s (night) to 90s (day)... tried replacing batteries in remote... (new alkaline)... nothing... then tried replacing batteries in main unit... put remote directly beside main unit IN THE HOUSE... let sit for a day... not stuck anymore, but "outdoor" temp always 2-4 degrees warmer than inside (even though they are BOTH inside and side by side)... tried resetting both with new "A-B-C" setting... let sit for day... still 2-4 degrees off... so I ORDERED A NEW REMOTE... went thru proper order bringing up remote first, then main unit, tried new "A-B-C" setting... let sit for day... "outdoor" temp is STILL 2-4 degrees warmer, even though both the remote and indoor unit are side by side.  I guess the indoor unit must have a bad receiver and is defective?  Thanks for any help, or will AcuRite replace the unit under warranty?

Hello Kevin,

The accuracy standard on our digital products is +/-2 degrees.  What is the name brand of the batteries you are using. We do recommend following the battery guidelines below: 

You want to use something such as Rayovac, Energizer, Duracell or Kirkland.

  • Verify you are using fresh alkaline batteries or lithium batteries (when temperature is below -4oF/-20oC) in sensor.
  • Quality brand batteries are recommended, including Duracell, Rayovac, Energizer, or Kirkland.
  • Verify batteries are fresh. The battery expiration date should be at least 6 years out. Batteries can lose 3% power or more every year in storage.
  • Heavy duty, extra strength or generic / store brand batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the way these types of batteries disperse power. Each battery should not exceed 1.6 volts.
  • Rechargeable batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the voltage instability of these types of batteries.
  • Mixing different battery types (brands, old/new, etc.) is not recommended.

I appreciate that the variance is +/-2 degrees, but I said it fluctuated 2-4 degrees.  I guess I should have included a screen shot of the greater variance I routinely see (attached).  The main and remote unit have been side by side for days.  You provided a canned response about battery recommendation which does not address the issue with the wider variance I experience.  I said in my problem description I was using "new alkaline" batteries, and I'll add that I tried several brands, Rayovac, Duracell, and Energizer.  So your response is pretty much useless.  I guess I'll just need to accept that the outdoor temp may be 2-4 degrees off, not the worst problem I have in life.

Hello Kevin,

 Your weather station is reading within the standard accuracy. The standard accuracy is +/- 2 F per unit. So this means that the display will be +/- 2 F and so will the sensor. When comparing two AcuRite products there may be a 4 F difference. Thank you.
