Sure we can. Marking the wires with a thermostat is a very critical hing as you have learned. This is why they give you many labels with the new thermostat.

You need to tell us exactly what color wires you have at the thermostat.
So you have absolutely no recollection of how the old one was wired? They are usually wired strictly according to color.
