Fan center relay wiring diagram - Also attached to the range, there is a line in, a three-conductor grounded line with a three-prong plug on the stop - for 120v electricity supply. There may be also a blower on the stove, which takes 120v electricity, and has 2 conductors - white and black. It forces the warmed air via the output duct. All of the wires are meet in a junction field, and none are related. How have to this be wired? I don't know what is supposed by means of "fan" and "limit". I'm assuming that "fan" refers back to the blower at the range. But what is the limit? I wager i simply don't recognize what the thermostat is doing with 2 lines entering/out of it. Mission: changing the mechanical cooling fan with a sucker electric fan. I was not content material with the small 12" lovers marketed by the triumph companies, however there is a clearance hassle between the radiator and the front frame rail (approximately three.5"). So choice of a fan to mount in the back of the radiator is essential. What is the yellow triangle with the #2 in it? It seems like the matters labelled l1 and l2 are the wires in the line in. L1 is black (warm) i guess, and l2 might be white. So i will wire the line-in white to the white conductor on the fan. Then the road-in black (hot) is going to the fan facet of the fan/restrict control. Wired to which conductor? White or black? If the thermostat is a simple transfer then i wager it does not rely. Then the alternative conductor (black or white) can get wired to the black line on the fan.
