when the new event setting saves energy, for example:
a)
In wintertime when the outdoor temperature is cold, you may set your vacation
temperature to 10°C to prevent pipes from freezing. However, if the utility company sends
an event to reduce the temperature to 8°C to save energy, it will override your vacation
temperature and make the new ‘Heat Set Point’ 8°C.
b) In summertime, if you have set your vacation temperature to 20°C and the utility sends an
event to increase the temperature to 25°C in order to save energy, it will override your
vacation temperature and make the new ‘Cool Set Point’ 25°C.
Note: The utility company cannot override your vacation temperature if you have set the unit to
