Daytime outdoor temp registering too high

  • Updated 2 years ago
I've had my model 02064C 5-in-1 setup since the spring, and on sunny days, it is constantly registering quite a few degrees higher than actual, and higher than neighboring stations. The difference is high enough that WU flags me for uploading erroneous data. I'm in a north-eastern  way upstate NY climate zone (not that much heat or compared to many other southern areas).
I have been reading the posts here, have twice so far opened the sensor unit to confirm that the fan is working fine, which it is. No debris, fan is spinning just fine - but obviously not fast enough to move enough air.
So if I am understanding correctly, AcuRite knows that the single solar panel won't generate enough power for the aspiration fan to spin at max speeds (during warm & sunny days), but expect me to go purchase a dual solar panel upgrade?
Pretty disappointing....why sell something that won't register proper temps, and then expect the customer to purchase extra equipment to get basic functionality?

Hello Eraie,

Can you please provide us with the 4 digit code located in the battery compartment of the sensor? It should start with QC. What are the difference in temperature readings that you are getting?  When comparing for temperature readings, we do recommend comparing to something at the same height and location. Leave them sit together for 1 hour, and compare the readings after that. Are you getting high readings when the sun is out or all the time?  Thank you. Have a great day!

Hi Jennifer,

QC 3715.
 
As mentioned in my post, this happens on sunny days. The temperature ends up registering so high, that I end up with my station being flagged and taken offline for uploading erroneous data. Compared to the many PWS stations around me, as well as the international airport a few miles away, I'm seeing as much as 8 to 10 degree swings in full sunlight. When there is no sun, or overcast skies, temps are back within normal local range.

In contrast, I have an Ambient Weather (Fine Offset) WS-2080 in the same spot, with a passive (non-aspirated) solar shield, and it does not end up with these wide temperature swings. Unfortunately, the wind vane and anemometer on the Ambient Weather station ended up damaged after 5 years of trouble-free service, and I opted to give AcuRite a chance.

There is no debris in the sensor housing, the fan is clear and spinning fine, and the solar panel is getting ample sunlight. So it doesn't seem to be defective....but rather (perhaps) the single solar panel can't generate enough power to spin the fan at full rpm....which seems to be needed on full sun days?

Thanks,
Elie

Mine is about 3 degrees High. I have adjusted my temperature setting down 1 to 1.5 degree lower so I have an average of the two. I have the double solar panel stile.

Hi Jennifer, it has been 3 weeks since providing you with the requested info....do you have a response for me?
