Underfloor and radiators ch

[Funkyfridays]

This is my central heating setup, combi boiler with ufh downstairs in zones controlled by the thermostats and radiators upstairs, how do i turn just the ufh on or off, or just the radiators upstairs on or off or both as i cant seem to regulate what comes on/off?

There are 3 floors, top two have radiators each controlled by a single thermostat not pictured, the bottom floor is ufh

 

[cross thread]

as we can’t see the wiring I would think the clock should do the rads and poly pipe stat the underfloor

 

[Funkyfridays]

For anything to come on i have to select the clock to on or the boiler mode to rad/water

 

[cross thread]

Boiler switch should be on for heating,would think the clock calling for heat should fire boiler and rads.
polypipe stat I would expect to be a timer as well would run the underfloor as the heat up times of the underfloor and rads are completely different.

If you wanted to just having the ufh on what would do please?

I have rads in house and UFH in kitchen room, I have two thermostats, and two zone valves, (shiny metal box top left of photo 20221016_205403).
You should have another of these (for the radiators, one for UFH).

My boiler (Combi) is set to constant, and the thermostats are used to turn UFH/radiators on and off individually.

There is only one valve in the whole house, maybe this could be faulty as i cant seem to get either the ufh or the radiators on seperaltey or even get any of them that hot for that matter?

 

[Funkyfridays]

With the clock switched on the boiler never fires up even though all the stats are on and calling, i need to turn the boiler mode to rads to get it to fire up but the floor doenst feel like its getting warm

 

[Mr Chibs]

Is there an 'on' or constant on the boiler?... I have to have mine set to this otherwise the thermostats are overridden.

 

[Funkyfridays]

This is the boiler
