Thermostat says Heat On, but furnace is not running


Hi Juliegeee. I am Roger. I am going to download you a programming sequence I put together that will probably help. To test and see if it is the thermostat before reading all that I wrote hear, Jump or touch the two wires together on the thermostat and see if your furnace starts and stays running. If it does, this post I made will help you to get it going. There are many manufacturers making many different digital thermostats. With residential thermostats, the variations of types, methods of operation and how to program them has gone far past the market need to just plain crazy. The only reliable place (?) to get specific operations and program manuals for your particular product, would be from "customer support" at the "manufacturers" web site or phone number. The "Model", "Serial" and "Product" numbers of your particular thermostat are usually printed on a small piece of paper pasted in its cover somewhere. In most cases, Just the Name and model on the outside cover will be enough for identification when asking a question or ordering an owners manual. That said, here are a couple things that seem to be fairly standard. This is the best way I found to program over the years. Remove the thermostat from its base plate. Be careful pulling on it. They don't all come off the same way and we don't want to break it. Before starting the programming process, it's best to erase whatever may be in your thermostat already. Overlapping time periods can cause a lot of trouble. Removing the battery's will erase any programming that may have been done before now. The factory program is just for basic operation and they don't normally have any schedules in them. The factory program will not be affected by removing the battery's. It's also much easier to do all this while sitting at a table and not hunched over at the wall. Remove the old battery's and replace them with new ones. The battery's are used to store your programming so be sure to put good battery's back in before starting. Here are some common terms used in programming a thermostat. If the names I am using for these procedures is different in your thermostat, change them when writing this all down. One "SCHEDULE" covers a 24 hour block of time. Each block of time from a start time to a stop time is a "PERIOD" in the "SCHEDULE". Again, these are the most common terms and may very in your thermostat. Here is an example of how to program one complete "SCHEDULE" ----- Get a large piece of paper and write down EXACTLY what you want your thermostat to do in ONE, 24 hour day. Here is an example of one "SCHEDULE" having 4 time "PERIODS". > ----- You want your furnace to start at 5:00 AM and warm the house to 72 degrees by 5;30 when you get up. Write down "72 degrees from "5;00 AM to 6;30 AM, or when you expect to leave the house. Then write down "62 degrees from 6;30 AM to 4;00 PM or 30 minutes before you expect to be home. Then write down "72 degrees from "4;00 PM to 10;30 PM or when you expect to go to bed. Then write "62 degrees from "10;30 PM to 5;00 AM or 30 minutes before you expect to get up.-----< You have just covered a 24 hour period of time and created ONE "SCHEDULE". Each day of the week needs a schedule. Various thermostats are different in how they handle schedules. You will need to read your "Owners Manual" to find out how your thermostat arranges its schedules. To get started, look for a "SET" button or touch sensitive area on the display screen. If there is no SET button you can see, check your manual for the button to press. That will put your thermostat in its programming mode. With some thermostats, the display will blink or change color to let you know you are programming. While in this mode, use the temperature set point arrows ( up and down) to scroll through all the different things that can be set ( Programmed ). When you hit one you are looking for, press the left and right arrows or buttons to set that function or time where you want it. Press the up and down arrows to get to the next adjustment, use the left and right arrows or buttons as before to set that function. Keep doing this until you have gone through all the various functions and set points. When you have gone all the way through, and have all the functions set where you want them, DOUBLE CHECK all your times and temperature changes against the desired operation you wrote down. Be extra careful none of your start and stop times for the temperature resets overlap each other. If you programmed in Holidays or special events you may have, be sure the TIME and DATE are correct. Press the "RUN" or "START" button to lock it all in and start your programs running. Again, be careful of overlapping the times in each "PERIOD" of each "SCHEDULE". That can keep your system running all the time or maybe even not at all. I hope all this will help you to better understand these complicated devices called thermostats. Thermostats are a deep subject and specific factory information in your owners manual may be needed to get you through. I hope this helps though. At least a little. Write it down before starting and be extra careful of overlapping in the time "PERIODS" and you should be OK. Good Luck, and let me know if you need more help. Roger

Honeywell thermostat won't turn the furnace on after power outage.


probably tripped a limit switch or a low voltage fuse would kill your display on the tstat, you should have battery power on your stat though.unless you have knowlege of electrical you better call a technician

Furnace cycles too frequently. Installed new wall thermostat,didn't stop problem. Furnace is installed horizontal in rafter space.


Systems are designed for a maximum of 6 cycles per hour. If you are experiencing more than that, you have leakage in your duct work or poor insulation or the system is too small for the area you are trying to heat. Some newer thermostats have an adjustment on them to allow you to set how many cycles per hour you want. Look in the instruction manual and adjust the DIP switches to your preference.

Hello, The first thing you need to check with a multimeter is if you are getting 24 volts between the R AND C terminal on the intergrated control board. If not than the transformer is blown and needs to replaced or the fuse on the control board has blown and will need to be replaced. When check for 24 volts at the R and C terminal make sure the door switch is pushed in, u can just use electrical tape to temporaily hold the switch in. If you are getting 24 volts at R and C and notthing continues to run than the intergrated control board is most likely the cause and must be replaced.

Totaline Thermostat either P/N 474-0100 or -0220


The power outage probably caused the thermostat to go back to factory default settings. You need to go through the advanced setup procedures in the owners manual on page 6. This will allow you to turn the heat pump back on.

Non-deletable schedule in VisionPRO TH8000


The thermostat has a function called "Adaptive Intelligent Recovery".

This feature allows the thermostat to learn how long the furnace and air conditioner take to reach programmed temperature settings, so the temperature is reached at the time you set. For example: Set the Wake time to 6 am, and the temperature to 70°. The heat will come on before 6 am, so the temperature is 70° by the time you wake at 6.

You can turn off this function. Download the installation guide at the next link:
http://customer.honeywell.com/honeywell/ProductInfo.aspx/TH8321U1006
and look for funcion number 0530 Adaptive Intelligent Recovery. In this manual you also find the way to do a reset with the function number 0710.

I hope this solves your problem.
