Well yes - except that I couldn't see any evidence of any such valves on the photos referenced by the OP.

Looking at the manifold picture, there are 6 "zones" but they don't not see m to have individual valves. Therefore the implication of this is that fro m the manifold perspective, the whole floor is on or off. Looking at the w hite/ yellow box wiring, it would appear that this is done by turning the p ump on or off. One would assume that there is a room stat (probably 1 per f loor) which switches this pump on when it calls for heat.
Given that the 2 floors have their own manifold and setup, to me, the sympt oms would suggest that the problem lies with the upstairs setup rather than any balancing between upstairs and downstairs - assuming that the central hot water supply is sufficient for both.
If this is the case, looking at the upstairs manifold, my troubleshooting s equence would be...
If you still have no heat.... not sure what to suggest. Air in the pipes?
thanks

I suspect ARW used "expect" in the sense of "it's what I would expect if it were my system". It doesn't look like there is any individual room control other than a lockshield valve on each circuit.

Looking at your plans, you have 6 circuits upstairs and 4 downstairs and that photo must therefore be of the upstairs manifold.
It looks like there is a four way manifold under the stairs downstairs. It would be helpful to know if this manifold has it's own pump.
If the upstairs just isn't heating up, it may be a dead pump in the upstairs system. The white box with the question mark is probably the overheat stat that trips at 60c to protect your floors. It doesn't *look* like the kind that needs resetting but you never know, if it has a reset button it won't do any harm to press it (working on the off chance that it's tripped at sometime and has cut the pump off).

On my manifold there are screw on caps which can (a) be screwed hard down to shut the circuit permanently off or (b) be replaced with a wax capsule actuator.
Ther are white caps on the manifold in the photo. Try removing em
Thanks for that Lee
Thanks Tim some more points to check out.
