Heating optimisation functions

  • Optimum StopSaves energy and money by switching off a little bit earlier than the normal programmed time. If your home is up to temperature, you will not notice the effect on the temperature, but you will see a difference in your fuel bill.
  • Delayed StartSaves energy by slightly delaying the start of heating depending on the difference between the programmed temperature and the actual room temperature.
