Installed an rth2510 and installed as labeled on old stat and sounds like my ac nut is buzzing outside, any thought?


question: do you have a multiple thermostat setup in 1 zone? If so check what settings are for your heat on each thermostat. Make sure that the heat is not set higher than the room's temperature.
check what settings are for your cooling on each thermostat. Make sure that the cooling is set accordingly.

if you have multiple thermostats setup in 1 zone. the thermostat with the lowest temperature will reign supreme. The heat setting on that thermostat will be what's causing the buzz on the heater.

optionally, hard reset your thermostat as a precaution. Here's how to do so: there are two types of thermostats i know of programmable and non-programmable.

disable auto & enable manual; however do NOT change settings or power-off t-stat. Remove battery and power down the thermostat until you see nothing on the thermostat monitor; power OFF the switch connected to your t-stat. Remove battery and reinsert inverted, if needed, press whatever button that your heart desires to make sure that nothing is absolutely drawing into that mode, button, etc; wait (5sec-1min); remove batters; wait 1min; then, reinsert batteries in its correct position; if you have a programmable thermostat; do the same with the hit 'reset filter' held down observe if the roomTemp reading has changed.

May I suggest to keep an extra thermometer around to determine if temperature reading accurately?

If reset requires a reprogramming to your t-stat, do whatever required to set your desired setting.

cheers, best of luck. i hope i've helped.

background, doing a hard reset in my opinion is similar to removing the battery from a PC motherboard.

Thermostat is heating house to desired temp before programmed time


there is a installer setup in this thermostat. do you still have the book?
you will need to gain access to the installer setup/programming and in it you will find a setting called auto recovery turn it off. what this does is after a few days of initally running the system figured out it needed to come on earlier and is starting before the set time to come on... you can turn it off and then will have to adjust depending on insulation value/construction type of home how soon you want it to come on so that it reaches desired temperature when you want...
hope this helps you out,,,

How do I set the temporary or permanent override feature on the Honeywell RTH2310B model thermostat?


To set the temporary override, press arrows up or down to desired temp. This will keep temperature
at temporary setting for 2 hours then return to programming. To permanent override press MODE button until schedule period number disappears (number inside little house on stat). Then adjust temp with arrows. Press the MODE button again to cancel override and return to programmable.

I just installed a honeywell 5-2 progammable thermostate.. Everything is hooked up fine and I have my days, hours wake, sleep, leave...etc all set, but when it goes on.. for example, I have it set for...


You didn't include a model number, so it's hard to know for sure - but I'll take a stab at this one. Many of these t-stats have a programmable offset to reduce "hunting". This can be as little as 1 degree or more than 2 degrees.

This means if you set the offset to 1 degree and the room temperature to about 65 degrees, the furnace will heat the room until the t-stat registers a rising temperature of 66 degrees. The furnace shuts off and will not turn on again until the t-stat registers a falling temperature of 64 degrees. The average is 65 degrees, and prevents the furnace from starting and stopping numerous times instead of just once with the 1 degree offset.

You can further reduce the number of furnace start and stops by increasing the offset to 2 degrees. This would work like this when the t-stat is set to 65 degrees and the room is cool:

Room Temp Furnace
63 On
64 On
65 On
66 On
67 On
68 Off

The room is now warm and heat or furnace is off. The room begins to cool like below:

67 Off
66 Off
65 Off
64 Off
63 Off
62 On

With a 1 degree offset, the room temperature varies +/-1 degree (about 2 degrees total). With a 2 degree offset, the temperature about varies +/ -2 degrees (about 4 degrees total).

Also, when the thermostat shut the heat off, the heat that was made is delivered to the space instead of wasted by sending outdoors - so the room will get a little warmer even though no fuel is being burned. The same holds true at the other end. When the t-stat turn heat on, fuel is burned, but there's little heat until the source has reached the optimum temperature and then the heat is delivered to the space.

I hope this helps & good luck! Pleas rate my reply - thanks!

My heat pump runs most all the time i will set the thermostat on 70 when it gets to 70 it still runs I can kick it back down to 69 and it kicks off.I can put it on 72 when it gets to 72 it still runs, I...


therostats have what is known as off-set deflection , or simplely put the plus or minus of the temp range which the heat turns on or off this setting is adjustable on many thermostats i usually set for 3 degrees if it is set for 1 or 2 it will run all the time refer to owners manual to see how to set this in program

Honeywell RTH2310 thermostat temp variance


Hi,
Yes you can change that by change the number of cycles per hour that your t-stat looks from for youe furnace. Lower the cycles per hour number and it will increase the range.

You can see how to do it here

Lost program instructions freezing


Hi, on a programmable stat, you should be able to raise the temp with the arrow and then push hold temp. feature. This will hold the desired temp and get you heat unless you have a stat problem. Try this and let me know the settings.If this didn't work, make sure the stat is in the auto-heat posistion. Push program and set the time.press again and set the day of week. Repeat this step and set the desired temp for each day of the week and week-end and push run program.You should hear it click on. It takes a min. or so on heat as there is a delay. Make sure the batteries are strong as they run the program. Let me no. Best of Luck, Sincerely, Shastalaker7

My honeywell central heating system turns off on its own. I set the room temp., the heating system reaches that temp then just turns off. The temperature drops and the system does not kick back on again to...


Hi, Just to let you know I have repaired central Heat & Air systems for 33 years and Have seen this problem on many occasions. Lets see if I can save you so many trips.It says you have a programmable stat? On this stat and on a mechanical stat, they have what is called a heat anticipator that controls how many and how often your thermostat turns you're unit off and on and how long it cycles after the stat is satisfied. If you have ever seen under the cover of a mechanical stat, ( mercury switch type) you will see a dial with an arrow with numbers as .1, .3, .4 1.0, or .15 to 1.0 amps.Some are fixed and some are adjustable. On a digital stat, you will have to get into the program and see what the heat anticipator is set on. They come from the factory at .4, but to really find out what you'res should be it takes an amprobe to do this. The setting you need is what you're gas valve requires.I am sure I have lost you, but I am just giving you a little food for thought. If you can get into you're program and set this to .4, great. If the problem continues, your anticipator on this stat is more than likely, shorted, which would require you to buy a new stat.With a shorted anticipator, it will seem to be working like you say, but when satisfied, the temp.keeps falling until you reset power, then it fires and repeats this. Change the stat. If this is central heat and air, just follow red-rc which will have a red jumper to rh for heat, white to w, green to g=fan, and yellow or blue to y = cooling. If you have central heat only, you will find 2 wires red and white.Red to rh with jumper still installed to rc and then white to w.This is quite a long explanation, but I wanted you to know a little more then the next guy about your stat. Please let me know.
Sincerely,
Shastalaker7

Cannot set heat setting by using "hold" feature


make sure it is not telling you room temp, some of the Honeywells, will display room temp over desired temp. check that, if it wont let you switch temp than buy a new one, if you dont have a heat pump a new cheap stat is around 20.00.
