Outside Temp consistantly high in full sun

  • Updated 2 years ago
My 5 i one outdoor sensor is consistently 8 to 10 degrees high.
I have removed the sensor and checked the fan area for debris, the fan does start in sun.
i re-mounted the sensor and I can hear the fan running.

it appears the fan does not move enough air to keep the temp accurate.
I am checking this against an outdoor thermometer, and early in the AM the temp spikes 8 degrees above actual, then on a very warm day it seems the heat builds up and again the temp is higher than actual.
This model came with a single solar panel.

Mine does the exact same thing. Mine has two solar panels. I pretty much ignore the thermometer in my 5in1 during the day since it reads 8 to 10 degrees higher than another AcuRite temperature sensor I have in the shade.

Can you tell me where you live?
I live in southern oregon.
I have heard this problem may have to do with your location.

Mine used to do this also. It somehow corrected itself, but I don't think the problem was the fan since it was also running. You may need to inspect the sensor chip that is just above the air intake on the bottom half of the housing. Maybe lift it out and check the chip for gunk and check the wire connections to be sure they are not loose. Hope this will help.

Hello All,

If the fan is functioning we would recommend upgrading the single solar panel to a duel.  The PRO+ upgrade was designed for excessively sunny or cloudy areas.  If you continue to have this issue please contact AcuRite Customer Support at 877-221-1252.  Thank you and have a great day.

In all my research this seems to be a design flaw. I have had this less than a year.
Seems this should be covered under warranty?

Hello Mike,

Is the fan turning on when the sun hits the solar panel?  If the fan is functioning, we would recommend upgrading the solar panels.  This would be an upgrade to the sensor.  Please let us know if you have any further questions.

do you get the "other" temp sensor to show on your inside console?

I have been checking my 5 in 1 against another thermometer (in the shade)

I would like to have just one that I could trust....

Hello Mike,

If you are asking if another sensor can be seen on your 5in1 display, then the answer is no.  You will only be able to view the 5in1 sensor on the display.  Please let us know if this answers your question.  Thank you.

I would suggest that you obtain a double solar panel cover for your 5-1.
The double solar panel is supposed to get the fan to move more air in sunny climates.

- also: make sure your unit us "pointing" south so that the panel captures as much sun as possible. That will also ensure that the wind direction indication is correct.

Can you tell me if the double solar panels increase the speed of the fan? I could understand this helps the early AM spikes.
Not sure what it would do for the afternoon spikes when the sensor is trapping the midday heat.

The fan does not run any faster, it just runs at all times the direct sunshine is hitting the sensor. If the fan is running and you still have a problem with being 8 F too high, I think you may have some other issue there...

Hello Mike,

Jon008 is correct, the fan does not run faster but the wind cup assembly has tilted panels so it can take in the sun from both east and west.  The fan will receive power at all times during the day.  I have provided a link below that will bring you to the PRO+ upgrade.    Have a great day!

Ok I just received the double solar panel. I noticed the housing was redesigned a bit to accommodate the two solar panels. It seems that there may be a little more air flow?
There are some additional holes around the wind cup housing.
I really want this to work out.
I have added a couple of images to show the placement of my 5 in 1.
It is located on a gable end of my roof about 2 ft above and close to a foot over the edge.

I'll try to watch the temp and report back in a few days
