What's the yellow triangle with the #2 in it? It looks like the things labelled l1 and l2 are the wires inside the line in. L1 is black (hot) i wager, and l2 might be white. So i will twine the line-in white to the white conductor at the fan. Then the line-in black (hot) goes to the fan side of the fan/restrict manage. Wired to which conductor? White or black? If the thermostat is a simple transfer then i guess it doesn't rely. Then the opposite conductor (black or white) can get stressed out to the black line on the fan. How need to this be wired? I don't know what is supposed through "fan" and "limit". I'm assuming that "fan" refers to the blower at the range. However what is the restrict? I guess i just don't apprehend what the thermostat is doing with 2 traces getting into/out of it.
