Given I have this (more advanced) thermostat downstairs, what should

Off??? (pretty sure its not going to be that last one).

If it is wired in to the same wires as the old stat and you haven't
messed around with the wiring at the other end of that cable. Then the
timer needs to be set to "ON".

Depending on how the rest of the system is plumbed and what other
controls you may or may not have independant control of the HW/CH.

Do I need the Hot Water on for the Central Heating to be warm ?

See above. Is this a fully pumped system? Is the HW on a gravity
primary loop? Is there a motorised valve (or valves) anywhere?
