I have a programmable noma thermostat... THM501... it kept on reseting the temperature on it even though it was programmed. I got so anoyyed that I pressed every button on the face plate so that this would not happen again ( even though I had no idea what I was doing... I have misplaced the manual) Now I am unable to manually adjust the temperature for my airconditioner.. it is now locked and I am sweltering... how do I unlock it to be able to adjust it again? PLEASE HELP!!

Here is your manual.
