9 Perfect Furnace, Switch Wiring Photos - But if your air handler or furnace is an older one that did now not include a door interlock protection transfer you'll need to cord the transfer in order that it interrupts electricity to the blower fan.
The yellow triangle labeled "2" inside the diagram is any device you want to show off while the temperature gets too excessive. The installation manual makes use of an oil burner as an instance of any such device. In your case you'll leave that switch unwired, until you need to rig up a solenoid valve to douse your wooden fireplace. :).
I've a wooden-burning range, that is used as an auxiliary heat source in the house. There may be a everyday electric powered furnace, and adjacent to it's far the stove. The nice and cozy air duct (out) from the range connects immediately to the enter air duct on the electrical furnace.
Also connected to the range, there is a line in, a three-conductor grounded line with a 3-prong plug on the stop - for 120v electricity supply. There may be additionally a blower at the stove, which takes 120v energy, 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 connected.
In pressured heat air furnaces in addition to air conditioning and heat pump machine air handlers the indoor air handler's blower compartment homes a fan, generally a spherical squirrel cage fan and electric motor (to function the fan) which actions air from the go back air plenum on in the direction of the cooling or heating coil. What's the yellow triangle with the #2 in it? It seems like the matters labelled l1 and l2 are the wires inside the line in. L1 is black (hot) i bet, and l2 would be white. So i can wire the line-in white to the white conductor at the fan. Then the road-in black (warm) is going to the fan side of the fan/limit manipulate. Stressed to which conductor? White or black? If the thermostat is a easy switch then i bet it doesn't rely. Then the other conductor (black or white) can get wired to the black line at the fan.
