Manuals for Filtrete 3M thermostats are available for download on the Filtrete Customer Help Center page on RadioThermostat.com. Links for operation guides and installation guides for each thermostat are listed down the left side of the page. A Wi-Fi setup guide is also available for relevant thermostat models.
The same manuals are also posted on individual product pages. Users who don’t have a model number on hand browse the product pages and view product images to identify the relevant model. The installation manuals include instructions for replacing an old thermostat with a new Filtrete 3M thermostat. Wiring instructions are included for eight types of HVAC wiring systems commonly found in homes.
