I know it sounds simple but the batteries are probably in the wrong direction. If they are correctly installed and fresh you will usually get a display.

    of course when you tried to reconnect the wires you may have burned your transformer out or popped a fuse. If the R and C wires touch for even a split second this is usually the case.

    Digital Thermostats are just small computers and they do break. When they do, the problem can manifest itself in any number of ways; erratic operation and just acting wierd can be some of them.

    If you have 24 or so volts to your thermostat from the transformer and/or fresh batteries or a circuit back to the common side of the transformer then the thermostat display should be showing...if no joy and you are sure there is power to it then I would replace it.

Honeywell thermostate will not kick off on set temperture


There's a "throttling range." The unit starts (say, in heating) one degree below setpoint and shuts off two degrees above set point.

You can change the "temp" but you can't change the throttling range.

Want to switch from C->F


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. That said, here are a couple things that seem to be fairly standard. Remove the thermostat from its base plate and remove its battery's. ts also much easier to do all this while sitting at a table and not hunched over at the wall. A "SET" button or touch sensitive area on the display screen will normally put a thermostat in its programming mode. With most thermostats, the display will blink to let you know you are programming. While in this mode, use the temperature set arrows ( up and down) to scroll through all the different things that can be set. When you hit one you are looking for, press the left and right arrows to put that function, schedule or time where you need it. Press the up and down arrows to get to the next adjustment, left and right arrows to set. When you get to the "F" or "C", select what you need then press the "RUN" button to lock it all in and start running all the programs. Be careful of overlapping the times in the schedules. That can keep your system running all the time or maybe even not at all. This may help some or not at all. Thermostats is a deep subject and specific factory information is needed for most of them. I hope this helps though. At least a little anyway. Roger.

How to end programmed heat settings on thermostat


Without knowing your model #, you can remove the batteries which will reset the clock and the programmed settings. You should be able to set the temp where you want and hit the HOLD button and it should keep it at that temperature until you hit hold again.

Issue with thermostat temperature control


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. That said, here are a couple things that seem to be fairly standard. Remove the thermostat from its base plate and remove its battery's. Its best to start with a clean program to eliminate the possibility of having entered something wrong previously that may cause you trouble later. Its also much easier to do all this while sitting at a table and not hunched over at the wall. The battery's are used to store your programming so be sure to put good ones back in before starting. A "SET" button or touch sensitive area on the display screen will normally put a thermostat in its programming mode. With most thermostats, the display will blink to let you know you are programming. While in this mode, use the temperature set arrows ( up and down) to scroll through all the different things that can be set. When you hit one you are looking for, press the left and right arrows to put that function, schedule or time where you need it. Press the up and down arrows to get to the next adjustment, left and right arrows to set. Keep doing this until you have gone through all the various set points. When you think you are all done, Press the "RUN" button to lock it all in and start running all the programs. Be careful of overlapping the times in the schedules. That can keep your system running all the time or maybe even not at all. This may help some or not at all. Thermostats is a deep subject and specific factory information is needed for most of them.

Ac unit continues to run for as long as up to 45 minutes after it reaches set point. why? thermostat functions properly periodicaly. thermostat is about 15 months old. was installed at same as new heat...


this can be caused by several issues (1) Configuration program, this is not the program that you the end user set up for time of day programing. Nor set point. but how the T-stat is set up to operate for your particular system, A dead band change my be necessary.in most programable T-stats the system must get temp 1 degree below set point before the system will shut down (2) A relay can be sticking in the condenser unit keeping the compressor on when there is not a call for cooling. for this a good working knoledge of electricity is a must although the t-stat opeates on 24 volts there is high voltage in close proxcimity of control relays ranging from 120 too 240 volts (3) dust on the temp sensor can also be an issue dust act as an insulator not allowing the sensor too sense the Temp properly. (4) or that T-stat can and possibly has failed Electronic T-stat are suseptable too power surges although this is not a frequent occurance it is possible. I would reccomend having your local HVAC contractor check into this. depending on you Mechanical skill

I have a Honeywell programmable Thermostat (an expensive one that handles humidity, etc) and every spring and fall the thermostats behave improperly by ignoring the programmed temperature and cooling the...


What is the model number of the thermostat? What may be happening is the humidity control is trying to satisfy the humidity setting by running the a/c. In the installers set-up, there should be a setting to determine how long the system should run to satisfy humidity setting. I typically set thermostats for a 3 degree droop. Meaning it'll only drop 3 degrees below set temp. Also check your humidity setting to be sure it's not set too low. It should be set between 45% and 50%.

With new digital thermostat furnace runs every 10 min.


which type of T-Stat is it ? most standard t-stats have it built in that the temperature range is only a half a degree, it may seem like its running alot more, but in actuality it is maintaining better home comfort as it is not running as long as the old bimetal t-stats which would have a range of anywhere from 2-5 degrees which would cause the furnace to run alot longer, use more energy, use more fuel, and you would notice a definate change in the house temperture before it would come on or shut off, your t-stat seems to be working properly, and it will save you money, remeber also to change those filters !!!
