When the vacation mode is activated, your utility company can override your temperature setting 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 ‘Reject All Events’. Program menu To edit the time and temperature settings for any day of the week: 1.
