My temperature keeps dropping at different times of the day, but esp. at night before 9pm
And even though the number on the right says 69 the left side says 63-it does this a few different times during the day & I have to play with it to get the heat on again.
I have a White Rodgers programmable thermostat & maybe I am running it on a program without realizing it-how do I maintain 1 constant temperature as I used to at 67 degrees?
I cannot find my manual.Thank you!

What is on the left? Room temperature?
