Starting from cold, with all to off and all stats down.
On the programmer, switch hot water to on. Anything happen? If no, good.
On the hot water cylinder stat, turn up the stat till it click. Do boiler and pump run and the heated water is going to cylinder flow connected? If yes, good.
Turn cylinder stat down, do the boiler stop, and pump (pump over run) continue to run for a few minutes then stop? If yes, good.
Switch off hot water on the programmer.
On the programmer, switch on heating to on. Anything happen? If no, good.
Turn room stat till it click. Do boiler and pump come on and the heated water is going to radiators? If yes, good.

From cold, on the programmer, turn both hot water and heating on.
Turn both hot water and heating stats on.
Boiler and pump come on, heated water should spilt up and going to hot water and heating. Is it working?
Turn down room stat, heated water should stop going to radiators.
Turn down cylinder stat, boiler should stop and pump continue to run for a few minutes then stop.

Reading through it though and taking in mind each test may have been days apart, I will
try and do the full test from cold at the weekend, currently got builders in who keep
using the water and turning the power off to verify the results
All fine upto *********************
Hot water and heating on, water does not split between water and heat, it chooses one or
the other, i think its based on the water temp in the tank myself. Both temps set to 60 then
we got hot water, when he switched the rad upto 68 we got heat.
Boiler comes on and today it switched to heat only despite both water and heat on the panel
set to always on not timed. Tap water lukewarm.
Switch the stat down on either one and boiler switches off, totally ignoring the demand for
heat from the other stat.
They changed the valve in the airing cupboard and the programmer/timer with no success.
