Early-On feature not working

[Wilma58]

We've had the thermostat for two weeks now and it still isn't turning on the heat soon enough to get it to temperature at the set time.  "Early-on" is turned on and the "Choose Maximum Duration" is set for 5 hours.  BTW - as I'm typing the house is now up to temperature - 1.5 hours LATE.

Hello,

One thing to consider it that it takes some time for Early On to learn how long it takes to raise the temperature in a particular house based on the outdoor temperature and the number of degrees it needs to be raised.  For example if the temp needs to rise 5° F and it is only 15° outside it will learn it takes XX minutes, but if it is 50° outside it may take half that time. 

Do you know if it is trying? Let's say you want it to warm to 70° starting at 8:00 am in the morning. At night the temperature is set to 65°.  If before 8:00am the heating starts working and the temperature starts to rise above 65° it is probably trying. If at 7:59 AM it is still 65° in the house it probably is not.

Thank you for the explanation. 

We had a 20 degree cold snap the other morning and the house wasn't heating.  LSS - Last month we had a new heat pump with gas furnace backup installed.  The technician forgot to turn on the gas furnace so the heat pump was trying to do all the work.
