There is no other writing to suggest the model number of the thermostat?

Based on the box by the boiler this suggests the thermostat is a wireless one, but there are many different thermsotat and would really need the model number of the thermostat to talk you through a reset.

it is a wireless one, but no other information on the outside plastic covering, it was installed about 2 years ago, maybe on the inside somewhere there is more information on the model number, is it ok to open up?
Customer: replied 1 month ago.
the inside of the timer has the following
FP/CP715-Si
P/N 38072
does this help?
the thermostat in the hallway has no ref numbers or letters
the screen shows 0F (the f blinking)

This points towards a faulty thermostat, so would look to replace the thermostat.

Once you remove it from the wall there will be a label on the back with a model number, if you provide me with that I can direct you to where you can find a replacement.
