I have anoma2 thermostat with no instructions on how to program it

They have instructions here. You will have to type in your model to get the instructions.You can also look in the sticky notes at the beginning of the board.
I just thought I would mention that NOVA thermostats are not a good product in my opinion. I would get a Honeywell.
