solar hot water cylinder - direct and indirect thermostat

[wertert]

Hi All

I have a Santon Premier Plus solar hot water cylinder.

It has 2 plastic housing covers on it's side. The lower is for the solar heating temperature probe so I know what is happening with that one.

I have attached an image of the top cover.

According to the manual it contains 2 thermostats. The small brass wheel ( 1-5 ) is the indirect thermostat which, I think, sets the maximum temp of the hotwater cylinder. I'm not sure what is going on with the other direct thermostat. ( blue plastic wheel thing 1-5 )

I'm assuming it's something to do with an immersion heater ? I am also assuming that it isn't connected up as we're missing a cable to supply it !?

I am not planning to make any changes to the system. This is purely Information only at this time.

Thanks

Hi Matt

At the risk of looking completely ignorant
Is the round item with the blue plastic thermometer actually
A heating element which is not wired up ? Ie immersion heated

Thanks

yes it is, well acually it is the plug on thermostat for the element but the connections are made to it.
