Is this your own panel ? i.e. was it purchased from new by yourself, or was it installed by a different company. If by a different company, note that a feature of Gardtec as regards the engineer code is such that if it starts with a 9 it can not be changed unless you know the original engineer code, that's the code the installing company uses and not the default engineering code as shown in the manual.
