3.CONDITIONS FOR TESTING THE SMART CONTROL COMPLIANCE (SMART) OF WATER HEATERS

Where the manufacturer deems it appropriate to declare the value of smart as being ‘1’, measurements of the weekly electricity and/or fuel consumption with or without smart controls shall be carried out using a two-week measurement cycle as follows:

  • days 1 to 5: random sequence of load profiles chosen from the declared load profile and the load profile one below the declared load profile, and smart control disabled,

  • days 6 and 7: no water draw-offs, and smart control disabled,

  • days 8 to 12: repetition of the same sequence applied for days 1 to 5, and smart control enabled,

  • days 13 and 14: no water draw-offs, and smart control enabled,

  • the difference between the useful energy content measured during days 1 to 7 and the useful energy content measured during days 8 to 14 shall not exceed 2 % of Qref of the declared load profile.
