Hello, it will be easiest to simply replace the thermostat with a non programmable model, however if you can pry the existing thermostat gently from its wall mounted sub base, and hold it in your hand, and get me the brand name and the numbers from the back of it, I can most likely pull the manual on it for you.

We can go from there.
