The cold side is 80.0 on the floor and approx 77-78 ambient air temps
The hot side is 90.00 on the floor and approx 81-82 ambient air temps

The cold spot area is 864 square inches
The hot spot area is 288 square inches

What would be better moving forward:

1) Set the hot spot to drop from 90.0 to 87.0 at night, from 7:00PM-7:00AM
2) Set the hot spot to 88.0 24/7

My updated setup:
