You can’t....the wiring centre is 12V. You would have to replace wiring centre with 230V version.

Good point! If I replace with a 230v wiring centre. Will the nest be compatible? The hot water goes through a separate programmer not through the contol center.

Why not call heatmiser, maybe they could intergrate the neostats into your system that can be remotely individually controlled via the neoapp, i belive they are 230v so might be a problem with your existing wiring. Worth giving them a call though.
