If it was freezing temps outside, I would keep the thermostat set low during the day if gone, as it would help keep condensation down. Ours is never about 9°C (48°F) anyway, unless we bump it a bit for changing, or should we be sitting inside.
If gone for multi days, I would just shut it down for that time.
