I have a Digistat3 room thermostat, it is not connected to the central

it has worked ok for a few years but recently stuck at temp 34C.
Batteries are new and I have tried sticking it in the fridge but still
registers at 34C.
Not an issue if I have to bin it but is there anything to try before I
do that?

Is it stuck on 34 as a "demanded Temp"? Some button pressing been done.

Yes, I find our room thermostat very confusing from that point of
view. Very counter-intuitive in button pressing terms.


Messed with all the buttons and no change, so took batteries out and
left for a few minutes, replaced batteries and back to normal now. Doing
this probably reset it.
