I have a Honeywell thermostat with M-F schedule like so…
- 6:30 am (wake) – 70
- 6:45 am (leave) – 63
- 4:00 pm (return) – 70
- 9:00 pm (sleep) – 63
The Honeywell actually displays wake, leave, return, sleep when setting it. Now at 5am this morning, the target temperature was 70 degrees and it was heating the house!
-
Is this normal, is it trying to take 1 hour and 30 minutes to get to 70 degrees? (This seems wrong…I don't want it to start heating until the wake time is hit TBH).
-
If that is wrong, is there a factory reset (as clearly this thing is way SCREWED up)?

It depends. Let's back up and talk about what Honeywell likes to call "In Recovery".
When you set your thermostat up, the thermostat has to learn how fast your HVAC can change the temp. It does this during a natural cycle so you're not running your heater in Summer or vice versa. Once it knows about how long the process will take, it will then kick the HVAC in so that it reaches your desired temp at the time you set it for. In other words, when you set it to 70 by 6:30am, it's going to kick your heater in earlier to reach that temp by 6:30, not to start trying to change it at 6:30.
Now, 90 minutes for a 7 degree change sounds nuts but if it's stuck in learning mode it might be confused as to how long it takes. You might want to consult your manual (or call Honeywell) and see if there's something not correct there.
