I own an intertherm furnace and i be wondering hhow to translate the speeds on the blower i own already tried? switching the wires around like the instruction book says but i hold...
switching the wires around like the instruction book says but i hold not noticed any difference within the speed
Answers: first off why are you trying to renovation speeds? unless you are adjusting temp rise...dont
some blowers are not adjustable
some own an A B & C on a connector on the motor housing and you switch the hot lead here.
some blowers have 3,4, or 5 lead that tap onto the board. on these boards in attendance are "park", heat and cool tap as well as the nuetral or adjectives tap. the fry speed comes on in fry or when there is a "G" telephone the cool speed comes on with a "G" + "Y" bid the cool speed is usually one speed higher than the fry speed.
Possum, hvac guy
As possum said, dont mess with the enthusiast speeds, they are set for a reason. If you turn the fry speed up too much, you get a lower heat rise. In other words the incoming air to the furnace is say-so 68 degrees, when it go through the heat exchanger it comes out at speak 128 degrees, giving you a 60 scope temperature rise. This is what you perceive at the registers. If you turn the fan speed up the heat rise decreases. Instead of 128 degree you get more close to 108 degrees. The existing down side is you are cooling your heat exchanger too much and this can raison d`¨ētre incomplete combustion resulting in lower combustion temperature and faster corrosion of the heat exchanger due to increased condensation contained by the flue gasses. If you are trying to get more steam at the end of your trailer, tweak the closest registers to the furnace closed a moment or two bit , and open the extreme ones up all the course. Dont go around closing them adjectives or you will restrict the airflow from your furnace and cause the heat rise to be too high which can also desecrate the heat exchanger.
