SOURCE: Honeywell thermostat RTH230B

After several months of calling Honeywell (actually someone in India), I found what seems to be the solution. I think I became such a pest (they had a lot of complains from me in their record) that they put me on hold and called someone at Honeywell Corp. The solution was to "reset the microchip". You do this by holding down the "Mode" button and while holding it down, take the batteries out for a couple of seconds (still holding down the Mode button) and then put the batteries back in and release the Mode button. 10 days have passed and it has been working perfectly. Hope this doesn'f jinx it! Good luck.

SOURCE: furnace will not come on but thermostat is showing information

turn off power to furnace and open the front panel and see if you can see burners and gas valve and Hot surface ignitor.
If you can. turn furnace on and watch to see if the ignitor glows.
Let me know what you find. If it doesn't glow you probably have a faulty Hot surface ignitor.
If I had make and model number I should be able to find the part

SOURCE: heater comes on at 5:10 am prior to the programmed setting

Access the installer setup menu (You will need the installation manual from the t'stat to do this) and turn off the "intelligent recovery" feature. This feature turns the equipment on in order to bring the conditioned area up to temp at the set time. Or you could set the "wake time" to 6:50!!!

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.

I AM GETTING COLD AIR AT NIGHT TIME. IF I PUT THEMOSTAT HIGHER THE AIR GETS COLDER . THIS HAPPENS EVERY NIGHT AROUN8:00 AND STAYS LIKE THIS FOR HOURS. JUST FILTER CHANGE


Is this Heat pump? if so what are the outside temperatures?
If heat pump there are controls connected to the thermostat that may at about 40f stop the heat pump, and switch to aux or emergency heat. If the aux is Electrical heating coil, you may not have power to the relay for the Electrical coil. If the Aux heat is gas, there is a problem with the controls. If none of the above are true, I would suggest your programable thermostat is calling for a lower temperatue at 8pm. I know termostats are not fun to program. It will take you some time to learn how, if you have the owner's manual. otherwise find the manual, learn, find a friend or family menber that knows how. Last resort change thermostat to non programable or have heating tec come by and help. Make sure everything else is ok in the heater.

I just had a 2 stage furnace put in and a 1 stage thermostat. The thermostat has been changed three times, but the furnace still won't come on as it's programmed to do. Where do you think the problem lies?


A single stage thermostat can be used on a two stage furnace, but there is a dip switch on the furnace computer board that will need to be changed, the directions are in the installers installation guide.
Also not knowing what type and brand of thermostat you have, leaves me guessing, some higher end thermostats have intelligent recovery, if you set it to 70 degrees, at 7 AM, it will try to have the temp to 70 by 7AM, so it could be coming on, even 2 to 3 hours early, depending on the temp. Most of them have a 7 day curve, so it takes awhile for them to adjust, this feature can be turned off, you will again need the installer's install manual.
I hope this has helped, please rate me and also get back to me if you have any more questions.
Sincerely,
Paul Gibson

When we are not at our cabin the temp is set to 57. Every time we go there and set it to 70 degrees the furnace will heat for 40-60 minutes and get to low 60's, then I notice hot air is not coming out of...


It sounds more likely that your fan is not pushing enough air across the heat exchanger. If you have a multi-speed fan, I would suggest increasing the blower speed. Otherwise you will continue to cycle on and off on the high limit. Also make sure that you do not have any return or supply vents blocked off, as this often times will cause the same problem. Hope this helps.

I have just had a new boiler fitted and wanted to run the thermostat (honeywell cm921) on auto, the electrician set the timer to come on at 1 & off at 2 disabled at 3 & 4 and on again at 5 and off...


Complicated because I need more info....but in General a Boiler should not be on a Programmable Thermostat as it takes too long to heat etc...do you have Radiators in your house???Or ductwork for heat???It will make a difference...if you put the boiler on a program it may come on anyway as some boilers maintain there own internal temperature regardless of the thermostat.....if you want to run it on a program adjust the temperatures so there is only about a 2 degree swing....70...down to 68....back to 70.....etc...there should also be a switch in the thermostat to set for Boiler...or Electric heat...make sure that switch is on...otherwise its difficult to give you a more conclusive answer

However - the problem is probably not with your thermostat but with your furnace. It is most likely a dirty flame sensor - a maintenance issue. If you have not had your furnace serviced recently (more than 1 year) that is where you should start. Modern furnaces require regular maintenance.

Thermostat temperatures not reaching preset Energy Star settings


Well with a boiler system like you have it will cost you more money to heat your house that way than if you leave it like it is. With a boiler system it takes a lot longer to heat an area than with a furnace. The best thing you can do is find a happy medium and leave it there at all times. If you read the paper work on your new thermostats they have a set procedure which tells the thermostat if you have forced air or boiler system. Do you have baseboard or in-floor heat how many zones do you have.
