As Davesparks has pointed out the terminal box on the cylinder with the strip of connectors has connections for the immersion and connections for the cylinder thermostat.
From left to right terminal 1 is common, terminal 2 breaks when temp rises above set point, terminal 3 makes when temp rises above set point, terminal 4 live immersion, terminal 5 neutral immersion and 6th terminal earth.
Immersion feed from double pole switch connects to terminals 4,5 and 6
Cylinder thermostat connects to terminal 1,2 and cpc in 6
2 connects to the brown of the hot water valve and an 1 connects to the terminal of the hot water valve connection in the UH4 where the rest of the hot water valve connections are terminated The heatmiser UH4 wiring diagram shows the connection of the valve.
