Heat loss/gain is proportional to internal-external delta T (and fabric U or R values, and ventilation).
In winter, allowing for time to warm up when you next expect to be there, you should consider the lowest temperature that will avoid damage from freezing of pipes and so on. Plus your fridge/freezer and a few other things will not enjoy getting very cold. FWIW I built in 6C as the 'frost protect' temperature for a heating control currently on the UK market.
