Set thermostat to desired temperature; lets say, 70 degrees Fahrenheit, a few seconds will go by then the furnace should activate. Once the furnace heats the room to the set temperature the furnace should shut off.
i have a model 125u19 payne furnace i move the thermostat but nothing comes on in the furnace and the pilot light is lit
Yes, a thermostat is required for an outdoor furnace. I recommend going to http://www.buycheapr.com/us/result.jsp?ga=us11&q=outdoor+thermostats for discounted thermostat.
There is always a wall thermostat for regulating furnace heat.
The negative feedback system. It works much the way a thermostat works. When the temperature in a room drops below a set level, the thermostat signals the furnace to turn on. Once the furnace has raised the temp in the room to the set level, the thermostat signals the furnace to shut off. It will continue to stay off until the thermostat signals that the temp has dropped again.
The power to the thermostat comes from the transformer in the furnace or air handler whichever you have. 1) the power to the furnace/AH is off, 2) the control fuse that protects the transformer is blown, 3) the transformer is defective, 4) the wire between the furnace and the thermostat got cut.

If the thermostat is open, the ohm reading will be O/L.
turn breaker off. unhook thermostat wire to furnace turn breaker on. worth a try; if it works you will have to turn off breaker to shut it down.
In the instruction manual for the furnace, it will either give you the heat anticipator setting or instruct you how to do it. If its digital, well then follow the thermostat instructions
A furnace by definition provides heat. There must be something that controls that heat; that is that tells the furnace when to fire up the burners and when to shut down the burners. This function is provided by the furnace control system. Usually the control system itself is controlled by a thermostat which maintains the temperature at a preset level on the thermostat.
A device for regulating furnace heat is the thermostat. A programmable thermostat can be set to control the temperature inside the home on a regular schedule. The thermostat is set to a desired temperature and then the furnace turns on and off to accomplish the desired heat level.
2 wires to the "R" and "W" terminals on the furnace. Usually the thermostat has similar terminals. If you have air conditioning, then there are 5 terminals to contend with. Look for a wiring diagram on the internet.
