What this means:  User interface faulty.


Action: Engineer will need to attend with replacement User Interface. The UI on parts list must be correct for the model/size of the heater.


If possible you should check the following items and if they are not correct you should contact your installer prior to raising a ticket for a service call.

 

      • Have the trips in your consumer unit switched off?  (switch back on if they have)
      • Check that the switches controlling the supplies to your product are on
        • There should be a switch (unfused) for the off peak supply
        • The continuous supply should not be on a plug
      • Are the supply cables different sizes, off peak supply should be on a 2.5mm2 cable
      • Have you set up the user interface (control on the top of the product correctly?
      • Have you registered your product
