afternoon,

I am currently doing a rewire and have come to the connections for the heating system.
What I have is a Worcester Combi Boiler and an Uponor Underfloor heating manifold.
I also have two zone valves 1 for radiators and 1 for underfloor, I have a thermostat in place to control radiators and then have to thermostats to control two areas of underfloor, there is no DHW parts as this just comes on when hot tap is ran.
I have a 2 zone programmer to fit along with an Uponor wiring box to take the control wires for each zone at the manifold.
I can’t seem to find any wiring diagrams that incorporate what I have, has anyone done one of these or similar systems before and if so any wiring diagrams or instructions will be appreciated.
Please see attached photos of what I have in front of me

Thanks in advance

Adam

you won't find a direct diagram. If you understand the function of each component and how it's intended to be used then is pretty easy to wire up.

As above, just be aware that the actuators on the manifold may be DC operated (12V or 24V). Depending on what the UFH stats are connected to you may need a couple of contactors to control the actuators (one for each of the two UFH zones).
 
Easiest to get a purpose made UFH wiring centre. Upnor probably make one.
 
The op says upnor wiring box.
sorry, missed that.
There should be all the wiring guidance needed supplied with the Upnor box.

OP which bit don't you understand?
