As of 2015, Intermatic provides downloadable instructions for its timers in PDF format on its website, Intermatic.com. Timer owners need their model numbers to find the correct instructions.
From any page of the website, customers click on Browse Product Documentation under the Product Resources tab to see a listing of products. Clicking through the Timers heading shows in-wall timers run by springs, electricity and mechanical means. The listings also include plug-in timers for indoor and outdoor use as well as those for appliances.
Owners of other timers can view four styles of in-wall and plug-in timers under the Mechanical Time Switches heading. Furthermore, the site lists specialty timers, such as fountain, portable and lawn irrigation timers, under the Specialty heading.
