Did you download and configure/install the WD Plugin? It has files like Settings-weather.php unique to each type of weather station software.
This is a quote from the Saratoga templates upgrade page:
The V3 templates have distinct settings files - the new Settings.php controls the overall website and support scripts, the new Settings-weather.php file contains weather-station software specific settings. This allows you to easily change to use different supported weather software to drive your site by simply installing and configuring a new Plugin for the new weather software.You can go to: http://saratoga-weather.org/wxtemplates/upgrade-from-V2-template.php if you want to review the instructions.
