20 Most Recent Honeywell prgrammable thermostat RTH2300B Questions & Answers

likely blew the low voltage blade style fuse. turn power off at breaker, remove blower door and look for a car like fuse.

Your tstat is not the problem. I've not yet worked on an oil furnace. I'm way down south. But either way, if your tstat was calling for heat(heat on), and you pushed a reset at the furnace, more than likely that reset is a safety. OK to reset, but now what ever that safety is preventing from happening, has failed and can not be reset until repaired. The reset should be an automatically opening switch upon unsafe operation. And manually closed to "reset" the safety. That safety is connected to something that is not working properly. Hope this helps!

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

It's either been rewired wrong or do you have a heat pump and this new thermostat no being compatible?

That's very unlikely. I'd sooner believe the cat has been playing with it or it gets changed when someone wearing a backpack brushes past it (sometimes the straps or zipper pulls snag the oddest things). You can get a thermostat guard to prevent this if your landlord permits it.

Question edited for clarity. Installation manual, but it has some very specific requirements. You may not have the correct one. The RTH6360 thermostat does not support L/A, S, or U terminals. If there are wires in terminals that are not listed, you will need additional wiring support. Visit yourhome.honeywell.com/support to find out if the thermostat will work for you. I don't understand that, and if you don't, you need a heating or electrical engineer.

I'm sorry to hear about the issue with your Honeywell ST699 timer. Here are a few troubleshooting steps you can try to resolve the problem:

1. Check the power supply: Ensure that the power is still on in your home or building. Check the circuit breaker or fuse box to see if any switches have tripped or fuses have blown. If necessary, reset the circuit breaker or replace the fuse.
2. Check the timer's power connection: Ensure that the timer is properly connected to the power supply. Double-check the wiring connections to make sure they are secure and not loose. Also, check if there is any visible damage to the wires.
3. Check the battery: If your ST699 timer has a backup battery, make sure it is not dead or discharged. Replace the battery if necessary, following the manufacturer's instructions.
4. Reset the timer: Sometimes resetting the timer can resolve technical issues. Locate the reset button or refer to the user manual to find out how to reset your specific timer model.
5. Call a professional: If the above steps do not resolve the issue, it may be necessary to call a professional electrician or the Honeywell customer support for further assistance. They will be able to diagnose the problem and provide a solution.

Remember to always exercise caution and follow safety guidelines when working with electrical components. If you are not comfortable or familiar with electrical work, it's best to contact a professional.
