Evening
Can someone clarify for me please if from looking at photo if this is likely to be an S plan or Y plan system as wiring up for 2 x Nest thermostats 1 for wet underfloor heating and 1 for central heating. Both the underfloor and the Central heating are only on 1 zone each. The valve on the left is under floor and to the right of this is central heating. Previous plumber has done one and just trying to decide on how to connect up wiring centre etc.
Thanks
