I. Presentation of the clock thermostat

The Exobox 7D has been designed to offer you comfort and energy savings.

It allows you to programme and adjust your heating according to 3 temperature levels :

  • "comfort" temperature : this is the temperature for your hours of presence.
  • "reduced" temperature : this is the temperature for your brief absences or during the night.
  • "frost protection" temperature : this is the minimum temperature for long absences. It protects your dwelling from the risk of frost.

3 pre-recorded programs and a blank programme will allow you to adapt your heating to your life style.

No need to replace the batteries, your Exobox 7D is supplied directly by its connection to the boiler "Saunier Duval".
