I am trying to locate a manual for my White Rodgers model 1F82-261 unit.

Try this (http://www.white-rodgers.com/wrdhom/pdfs/instruction_sheets/0037-6175.pdf).

How do I change the actual day on a white rodgers programmable thermostat when It list Monday through Friday and then the next segment is sat and sun. I need to change it to an individual day.

Sounds like you have a 5 day/2 day stat. Individual day programmability is featured on the 7 day version.

The manual for this model says it has separate 5-day (weekday) and 1-day/1-day (Saturday/Sunday) programming

My thermostat has a date blinking and the room temp is high than what I have set. How do I reprogram to meet the temp I want?

Thanks
