How do you test if a cylinder thermostat is working or not?

The reason I want to know the above is because I only get hot water when the heating is on thats why I think it maybe the therm in the cylinder any help would be appreciated.

If you turn it up, you will hear it click & the boiler should start

More likely to be the motor valve is faulty or it may have been wrongly wired.

Hi looked at system in a bit more detail, found what I think is a pump, its red hot, it has "controller 's' " written on it, when it is hot water only it does not supply to the cylinder but when the heating is on it does ( the return pipe gets warm) so I guess there might be a problem with this.

it has three pipes from it and what I thought was a syhncron valve and what looks like a solenoid.

written on the side:

controller 's'
SMC
220-250v 1hp 50Hz
90w 038a

if anyone could help?
