The Y1 designation on the end of the model number means that it is 3 phase.
If it was single phase it would end in V1.
Daikin didn't make that size unit in single phase in the UK as far as I know, The RY100 could be either 240v or 415v (RY100**Y1, RY100**V1) but the RY125 was always 415v.

I am looking for a wiring diagram for a RY100LY1. Unit not going on in heating, I suspect a problematic thermostat but would like to get a wiring diagram for when I return to site.
