Which part sounds strange?

At my previous rental location, the owner of the property made a request when I moved in. The property owners were just an average family, similar to the family that owns this multi-family house. They asked I keep the heat at 70. I requested 68 and they approved.

When I moved in, I found a new thermostat. Once winter came, I immediately set my program to 70 during the day and 68 at night.
