The thermostat isn’t actually doing anything in those graphs from about 7am to 4pm. There’s just a brief burst of heat to pump the temperature up in the early morning and a brief burst of cooling in the late afternoon. Of course the indoor temperature will be heavily influenced by the outdoor temperature. It’s being allowed to vary by more than 4 degrees C.

OK, maybe I misunderstood your original point.
