Just replaced my old Potterton EP6002 unit with the Potterton EP2. The 6002 was a 3 setting on/off unit, but I can only get 2 on/off setting periods with the EP2. The set up manual states that the EP2 can be programmed for the 3 settings, but I cannot get the option screen which allows this function to come up. The unit works fine other than this. Any suggestions welcomed as to how to set it up for the 3 settings option welcomed.
