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

Why blast furnace called as blast furnace?
Its because air is forced into the furnace to increase temperature. Steve.
What size forced air furnace should a 1500 square foot house have?
60000
If a forced-air furnace heats a house until all the air is the same temperature as the air coming from the furnace then?
no heat would flow

Why was power lost to a heat and air thermostat?
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.
Who makes the best forced air gas furnace?

Were does a thermostat gets its power from on a central air conditioner?
The furnace or air handling unit in the house.
What is the approximate external static pressure in the supply air plenum of a forced warm air furnace?
Approximate external static pressure in the supply air plenum of a forced warm air furnace is 0.2" w.c to 0.5 "w.c
You have an electric forced air furnace and central air. why does the central air fan run when furnace comes on?
You must have a heat pump with electric auxilliary heat.
Why is the heat and air system only working on emergency heat?
when running the heat-pump the air blowing from the heat ducts is not hot ( it's to cold for the heat-pump). you have a main furnace and it won't turn on ( is thermostat selected for this source), ( is the power switch for main furnace on ), ( is fuse for this furnace good). If these are good (check thermostat wiring at thermostat, and transformer).
Why wont your forced air furnace come on?
Here are some things to check. Is the thermostat turned up? Sounds silly but I went into many homes it was turned down, or the switch on the thermostat was turned to off Is the pilot lit? This assumes you have a standing pilot furnace. If it is spark ignition, does the park cycle start. Check all fuses and breakers
How do you install heating thermostat only for furnace?
I am assuming that by asking about a "heating thermostat" for a "furnace" we are not talking about air conditioning/heating units or about electric heating units (baseboard, wall-mounted, etc.). If the furnace already has a thermostat installed then it is just a matter of replacing the existing thermostat with a new one. Heat-only thermostats can be obtained from home centers such as Lowes or Home Depot. They should be specified to work on 24-volt circuits, unlike those designed for 110/220 volt AC electric heaters. Replacement is simply a matter of removing the thermostat cover, detatching it from the wall, and disconnecting the two wires from the old unit. Connect the wires to the new thermostat and mount it to the wall in place of the old one. Be aware that some thermostats must be adjusted level to work properly - read the enclosed literature that comes with the new unit. If this is a new or replacement furnace that has never had a thermostat connected then there are several additional considerations. You will need to identify a location for the thermostat. This location should be on an interior wall, out of any drafts, and in a location such as a hallway which is an "average" of surrounding rooms. You will have to run 2-conductor thermostat wire (available at home centers) from the furnace to the thermostat. Connections to the thermostat are as outlined above. The connections at the furnace end depend on the type of furnace - passive hot air, forced hot air, passive hot water, circulator-driven hot water, steam, etc. These variations are beyond the scope of this general question.
