Are you saying that the temperature over-shoots it's setting by 5 degrees? If so and if the thermostat has an inticipator device in it you can adjust it. After removing the cover on the thermostat, look for a little brass triangle on the lower right hand side. There will be a scale with numbers on it and they are very hard to see. This device heats up prior to shutting off the thermostat so it will not over-shoot by more than a few degrees. Move the brass triangle either up or down and let the heater cycle a few times. If the temperature swing gets worse, go the other way next time.

If the thermostat is not heat inticipated, there will be a small "Dip" switch where you can adjust to a specific degree of under-shoot.

Visit the Honeywell website and you can pull up the installation/owners manual for your model.

Hi,My remote do not get the good temp in my house. Ex: I set to 80F in heat mode but the thermopump operate slowly and dosn't get hire than 70-72F. The remote see the unit and all. Is the sensor in th

You have a heat pump.
Once the outdoor temperature falls below 36 degrees, heat pumps will sharply lose their ability to heat.
If you are getting a 72 degree indoor temperature when the outdoor temperature is 28-30 degrees, the heat pump is performing up to spec.
On heat pumps, the air coming out of the nearest air vent to the unit should be heated approximately 40 degrees warmer than the air entering the unit.
If you have a 70 degree indoor air temperature, the heat pump should be supplying 110 degree air at the closest air vent to the indoor unit.
Gas heat is a much better heating source where outside temperatures are commonly below 36 degrees.
Even electric furnaces perform better than heat pumps under these conditions.

So the furnace will come on and heat sometimes ? Then other times it will click but not heat ?

If your thermostat has an emergency heat setting this means you have a heat pump system.
Yes you need to set the thermostat to heat for heating the house.
The emergency heat setting should never be used unless your outside unit is not functioning.
The emergency heat setting overides the heat pump (the outside unit will not be energized).
The emergency heat setting will run the auxillary heat (heat strips) only.
When the thermostat is set in the heat position the heat pump will run to heat your house.
If the heat pump can't keep up (extreme cold) then then the auxillary heat will kick in to augment the heat pump until it satisfies the thermostat settings. If your room temperature gets 2 degrees below your thermostat setpoint, your auxillary heat will kick on. Example, say you are going to be gone a couple of days and you turn your heat down to 60 degrees. When you return and it is 60 degrees in your house, you turn the thermostat up to 70 degrees. Since you are turning the temperature up 2 degrees or more (10 degrees in this case) from the 60 degree room temperature then the heat pump will come on and the auxillary heat strips. The unit will continue heating like this until the temperature in the house gets to 69 degrees and the heat strips will turn off and the heat pump will continue to run until the 70 degree setpoint is reached.
Hope this helps.

Instead of the heating element turning on the heat pump runs out side thermostate is not set on eheat

The heatpump is your 1st. stage heat, when you have a call for heat it will bring on the outdoor unit.
When the first stage heat can't heat the house and the indoor temperature drops 2° or 3° then 2nd. stage heat will kick in and maintain the house temperature at about 2° or 3° below the temperature setting.
If you outdoor unit fails or goes into defrost then emergency heat will kick in and keep the house at 2nd stage temperature approximately 2° or 3° below thermostat setting.
If you have an outdoor thermostat or balance point setting on outdoor board, it will shut the outdoor unit off at a certain set outdoor temperature and the 2nd stage heat will be primary heat for the house.

When the thermostat calls for heat it should run until the room reaches the temperature setting then shut off. Is the blower motor running and can you feel air coming out of the vents? It sounds like the blower is either not running or putting out enough air to keep the furnace heating. The blower moves the heat from the heat exchanger to the room, if it can't remove enough heat from the heat exchanger there is a limit switch that will shut the burner off if it gets to hot and that's what it sounds like is happening.

Forced Hot Air Heating system doesn't maintain thermostat setting

It sounds like you may have issues with the furnace. A qualified professional can go over the system and the house to let you know if the system and unit are properly sized. The poor performance of a furnace can be a sign of carbon buildup in the furnace.
Good luck, hope this helps.

How do i operate thermostat and furnace

if your furnace is on 24 hours straight, before it heats up your home, then either your cold weather and indoor temps are extreme, or your unit is grossly undersized. if however your furnace cycles on and off when the temp is still way colder than you have set it you have either a bad stat that thinks its hotter than it is, or a bad furnace problem and even though the furnace is getting a signal from the stat to heat it is failing to do so. you'll have to watch and think this through to isolate the problem. if you set the furnace to max heat and it runs and heats the house reasonably quick then its probably going to be a bad stat. if you set it to max heat and it shuts off way before it gets to setpoint then the problem is in the furnace. be sure filters are clean, blower wheel is clean , returns are no obstructed, etc. if you by chance have an old mercury bulb stat they had a thing in them called a heat anticipator which basically worked like this. a dial with a little pointer determined how soon it would be till the furnaced reached the desired temp and anticipated how soon to shut off the burners in anticipation of the cool down period so you dont overshoot the desired temp. if these are bad or moved to different setting they can short cycle the furnace on of on off etc. or shut down the burner almost as soon as it lights. setting is usually at .4 to .6 on most, but really a digital stat is only way to go. by the way check to be sure you don't have a hot air supply grill blowing directly on the stat or it will shut off as soon as stat gets hot and rest of house will be cold. usual location is 5 feet off floor directly over the main return air grill or under it as the case may be. good luck
