It checks the temperature once a minute, and if it's below the threshold, it adds a minute to the Chill Hours total.
My system has been up about 2 weeks on Wunderground, and today.ini shows 7.3481 chill hours. I'm sure it is incorrect, we have not dropped below 45 degrees yet here in Texas.
I'm reasonably sure the code is correct, no-one else seems to have an issue. Perhaps your station is giving false readings - Fine Offset stations commonly do. I'd need to see all of your data files, and the ChillHourThreshold setting from cumulus.ini.
Second, we have had a high above 80 since I have started the system, chill hours should have been removed from the count.
Sorry, I don't understand, could you please explain? The Chill Hours figure has nothing to do with high temperatures, it just counts the period when the temperature was below a pre-set figure.
Is there a way to display chill hours from the system in Wunderground web page
No, Wunderground has it's own fixed set of data and you can't change it.
or on the Cumulus screen on my PC?
You can view the total on the 'This Year' summary screen.
