Here is a link to the exact same thermostat and how to set the dip switches.
I had to break it up with five dashes ----- when posting the link so it would go through on this sight so you will have to type it in your search bar without the dashes. I hope this helped...
I found the instructions for that exact Thermostat at this link, I hope it helps you out.
