    The orange/red led fan symbol indicates emergency heat is active. This could be because it is too cold outside for the heat pump to produce heat or you may have accidentally selected "emer heat" as your heat source. Look to see what is active on the lower left side of the screen under the "System" heading. If you see "Emer Heat" and it isn't colder than mid to low 20's you have probably activated emergency heat. Simply touch the "system" button and then select heat. The orange fan symbol should disappear.

Visionpro th8000 that is coming on early [ 2 Answers ]

We have a visionpro th8000 and the wake time is set at 6:15 AM. It is coming on around 4:30AM. I know it is suppose to come on earlier than what it is set at so it is warmed up when you get up. But an hour and 45 minutes sounds like a long time to me. Does this sound correct? Thanks for your help.
