Bad324 Posted January 22, 2013 Report Share Posted January 22, 2013 Since I'm new at some of this home improvement crap I know a lot of you are quite knowledgeable and pointed me in the right direction with troubleshooting and tips so here is the newest one:I *think* my thermostat is going bad or has some issue. Over the last 3 days I have had it set to be a constant 70* and it keeps dipping 4-5* and stays there awhile before it kicks back on again. When it does kick on, the vents are pumping warm air and it eventually does get back up to 70*Q1: Is this a sign of the thermostat starting to fail?Q2: If I need to replace it, is it just a matter of pulling it off the wall then finding a replacement and wiring it in?

Go buy a new one and follow the instructions. FOLLOW THE INSTRUCTIONS. Just had to stress that one. It'll tall you to be sure to label the wires before you remove them. I took a photo. Same difference. Just be sure to know whether you have a one stage or two stage furnace, and whether you have a heat pump or not. Quote Link to comment Share on other sites More sharing options...
Tpoppa Posted January 22, 2013 Report Share Posted January 22, 2013 Is it programmable with different time zones? If so, you you need to program all the time zones to 70 degrees or it will revert back to the programmed temp. Quote Link to comment Share on other sites More sharing options...
Gump Posted January 22, 2013 Report Share Posted January 22, 2013 Some of them you can program the swing. Meaning the amount of degrees it drops before kicking on. Or number of degrees it rises before turning on the air. Maybe yours reset or something. Quote Link to comment Share on other sites More sharing options...
shittygsxr Posted January 22, 2013 Report Share Posted January 22, 2013 Stats have a variance that can be adjusted for example set at 70 it might turn on at 68 and warm to 72 before shutting off. The variance can be set from +- 2 to +-5 Quote Link to comment Share on other sites More sharing options...
jbot Posted January 22, 2013 Report Share Posted January 22, 2013 one of these days, i'll take a pic of mines wiring and maybe some of the experts can chime in. it has WAY TOO MANY FREAKING WIRES for being just a simple thermostat. it looks like it should have an associated heat pump, but there is no heat pump.

blue03636 Posted January 22, 2013 Report Share Posted January 22, 2013 Is there a way for a thermostat to display a higher number in the winter so my wife doesn't think I lowered it. Quote Link to comment Share on other sites More sharing options...

ReconRat Posted January 22, 2013 Report Share Posted January 22, 2013 To make it worse, every furnace and thermostat I've looked at, would have random hookups for the various colored wires. Definitely take a picture or notes.Extra worse, those schematics on the furnace can often be wrong, or look nothing like what the installer actually did.Other than that, they are fairly simple, and it's not too hard to figure it out. Even if you have to go see what those wires are connected to on the furnace. Quote Link to comment Share on other sites More sharing options...
ohiomike Posted January 22, 2013 Report Share Posted January 22, 2013 one of these days, i'll take a pic of mines wiring and maybe some of the experts can chime in. it has WAY TOO MANY FREAKING WIRES for being just a simple thermostat. it looks like it should have an associated heat pump, but there is no heat pump.Usually there are just four thermostat wires coming from the furnace. Red, White, Green and yellow. Older houses used 2 wires (no AC). Casper is correct, make sure you mark the wires you take off the old t stat. By the screws there should be letters-B or Y or W or G. Just re attach the wires to the like marked screws (terminals) on the new T stat. EZ as 1-2-3. Quote Link to comment Share on other sites More sharing options...
jbot Posted January 22, 2013 Report Share Posted January 22, 2013 see, at my old house, it was simple, 4 wires, done.the new house has freaking 6 or 7 wires (including an orange one), definitely NO heat pump (well, as far as I can tell). there is a humidifier attached to the furnace(s) (there are 2, 1 is for first floor, 2nd smaller one is dual zone for 2nd floor and basement as far as I can tell) and then a pair of AC units outside. the one for the 1st floor is the one I was going to change the thermostat to a programmable one but then there were a gazillion wires so i didn't do it. why they didn't put in a programmable one in the first place, i will never know.

This is the exact same one we had at the townhouse I lived previously and we made that mistake the first winter not knowing it was capable of that Quote Link to comment Share on other sites More sharing options...

Cheech Posted January 23, 2013 Report Share Posted January 23, 2013 I've got a Trane heat pump, and swapping my thermostat out was the first and easiest thing I've changed on my house. If I, a librul socialist moron with shit for brains can do this, you should be just fine. As was said, just label or take a bunch of pictures of all the wires as they currently are.

twowheelsnake Posted January 23, 2013 Report Share Posted January 23, 2013 The nest is awesome! It is wifi enabled, accessible from the outside, it learns your patterns and sets energy settings accordingly. I could go on but you'd be better off just visiting their site.

serpentracer Posted January 23, 2013 Report Share Posted January 23, 2013 (edited) sounds like a cheap thermostat. if it's not digital get one.if it is digital they have a heating cooling cycles per hour setting that may be wrong. I have a cheap $25 honeywell, it's instructions online show a bit about this setting. (part 4)maybe it will help you,https://customer.honeywell.com/resources/techlit/TechLitDocuments/69-0000s/69-1799.pdf Edited January 23, 2013 by serpentracer Quote Link to comment Share on other sites More sharing options...
2talltim Posted January 23, 2013 Report Share Posted January 23, 2013 Get a Nest. http://tinyurl.com/a5onpwklooks cool but im not got to spend $250 on a thermostat:eek:..damnive got basic digital(cant remeber the brand right now) that i paid like $20 for, thats been on mine for 10 years and it works great. No need for all the fancy crap on it i set it for 67 in the winter and 73 in the summer and never touch it other wise. Quote Link to comment Share on other sites More sharing options...
Bad324 Posted January 23, 2013 Author Report Share Posted January 23, 2013 I like having cool fancy stuff but I'm the same way when it comes to the thermostat. Its usually set at 68* year round unless it gets super cold and the GF wants it turned up. Which frankly is okay by me since she pays the billI didn't get time last night to pull it off the wall and see but I think maybe I'll try and get the model number and google up some troubleshooting. Last night I just left the fan on ON instead of AUTO to alleviate the issue until I could get time to look into it Quote Link to comment Share on other sites More sharing options...
