Can fully bottom grill block in 60F weather.

Thermostat arrived. Still planning to install Friday night. But these last 2 morning, it's been about 48F. My heater seems to be working now or something. Maybe it's just warmer? So I press auto and set the temp to 80-high. It goes to floor vent, fresh air, fan 0-1 bar. However if I put it on face or face and feet, it turns the blower on about 5 bars. In about 5 minutes it starts blowing warm air, which that part is normal.

I thought normally no mater what vent I selected, it wouldn't turn the blower on until the engine was warm enough. When on auto. I haven't had my scangauge 2 plugged in for about a week now, so I have no idea what temp it was. I had previously been using face and feet, but it seems like face warms up so much more? Idk, I'm not explaining it the best and it doesn't make sense to me right now.

I still plan to change it, because even when it's 90F out, I think my coolant temp barely hits 160-170F on my 20min~ 7 mile drive to work. Going to either figure out it's normal or something was wrong with it. As far as I know, it's the original.
