Sorry it has two two port valves
So you supply the boiler and the boiler has an internal connection labelled 230V out and all the control wiring needs feeding from these terminals as they are protected by the boilers internal fuse. This is a requirement of the manufacturers instructions and may void the warranty if not wired as such.
You need a to feed the boiler from a switch fused spur with a 3A fuse connected to the 230V in terminals.
4 core flex from boiler to wiring centre which gives you LNE out as explained above and switched live which connects to LR with the radiator symbol.
5 core flex to dual channel receiver from wiring centre.
3core flex to cylinder thermostat from wiring centre
obviously both valves back to wiring centre
First of all connect all cpc's together to get them out the way
Same again with neutrals from boiler, receiver and both valves
Connect all permanent lives together L out from boiler, L from receiver and both greys of the valves
Brown from central heating valve connects to terminal 4 on receiver
Common from cylinder thermostat connects to terminal 3 on receiver
Normally closed on cylinder thermostat connects to brown of the hot water valve
The oranges from both valves connect to LR with radiator symbol
As its an unvented cylinder the cylinder thermostat will have a high limit thermostat and temperature control thermostat contained within the same enclosure so HW ON from receiver connects to common of the high limit thermostat, normally closed from high limit thermostat connects to common of the temperature control thermostat and normally closed from temperature control thermostat connects to the brown of the hot water valve (connected in series).
