Thermosat says "FR return"

And I’ve never seen that before. Google isn’t saying much, so does anyone know what that means and is it a bad thing?

Friday. Return.
You are in program mode, and you are at the point where you set/view the desired temp you would like to have when you return on Friday.

Usually there is:

Wake, Leave, Return, Sleep. On some models, you program each by day. Yours is simply on 'Friday Return". What temp do you want on Fridays when you return? Also, you define the return time.

For example:

FR Wake: 7:00am
Temp: 69

FR Leave: 8:15am
Temp: 78

FR Return, 6:00pm
Temp: 74

FR Sleep, 11:00pm
Temp: 72
