Yes. Look at the second picture and you can see the lever. It
will feel quite stiff because as you slide it along it manually
spins a small motor inside. Pull it all the way as far as it can
go then push it up and it will hook into a small recess to hold
it open, otherwise it will slowly spring back. If your boiler is
on then you should get both CH and HW.

You are assuming it is a mid position valve and hence able to direct
water to both CH and HW circuits. If it is a diversion valve then it
will only do one or the other, never both.
