I need to purchase a few temperature controllers; I'm interested in this one but I'm not sure if it will work in North America without blowing up or melting something or other adverse and undesirable things. [more inside]
We have this furnace. In the summer it would be nice if we could run only the fan (We don't have central air), but according to the manual, Fan Only Mode requires the R and G thermostat contacts be wired. As you can see, only the RC/RH and W contacts are wired. Would simply swapping the orange wire from RC/RH to RH/G create the circuit needed for sweet, sweet fan action, or will it be necessary to run a new wire from G to the control board in the furnace, therefore requiring professional help?

When my central air turns on or off, I hear a loud popping sound coming from the thermostat area. I have replaced the thermostat and still hear it. I'm sure that I have always heard it and that other ac's have made that noise but, for the past few months, it seems to have gotten louder and it wakes me up throughout the night. It is driving me crazy. Is your thermostat that loud? Could this be an electrical issue? [more inside]
I live in a drafty old farmhouse. My roommates and I are currently waging a thermostat war--one says it's cheaper to to have the heat for the whole house at 70 than it is for him to heat his room with a space heater. I maintain that its probably way more expensive to heat the entire drafty house. Who's right? We have electric heat. [more inside]

I live in rented accommodation in the UK. The hot water is scaldingly hot. The radiators burn to touch. The shower temperature is hugely unreliable -- scalding or freezing. The landlord is worried that a plumber will rip him off, based on bad experiences in the past, and unwilling to pay to investigate. Can you help me understand what's going on? I'd like to put my landlord's mind at rest regarding plumbers, and set his expectations regarding likely diagnoses and solutions -- and hence cost. I also suspect this situation is wasting energy and hence driving up the cost of heating bills. I'd like to persuade the landlord that fixing it might be a good idea. [more inside]
A few months ago, my car's check engine light came on. They fixed it, it came back on again, they fixed it again, and now it's back on. I'm looking for possible explanations so I'm more prepared when I take it back yet again. [more inside]
We woke up this extremely cold morning (9F/-13C) and various electric things in our condo seem to be flaky, like there's not enough power. I also noticed that the thermostat for our heat pump says "Auxiliary Heat On", which I haven't seen before. Has anyone seen something like this before? Since it's all electric, it seems like it might be related. [more inside]

I need some thermostat programming tips. I moved over the summer and now I have a thermostat after many, many years of living with landlord-controlled heating systems and other curious and quirky forms of heating. Problem: the boiler takes FOREVER to heat up the radiators and then overshoots the target temperature dramatically. Details within. [more inside]
Just started renting at a new apartment. The lease includes a flat fee for utilities, but does not state that the landlord will have control over the thermostat/have the thermostat locked. I was never told that the thermostat would be physically locked and the lease makes absolutely no mention of it. In fact, the only thing in the lease about utilities is his single hand-written line stating "$100 flat fee for utilities a month." [more inside]
I just purchased a new Nest thermostat. My old thermostat gets power from an ancient millivolt system (thermopile on top of pilot light generates 0.7VDC). This is incompatible with the Nest, since the Nest requires standard 24VAC. Nest support told me they've heard some customers have had success using 24v step-down transformer. After lots of research, I think the wiring is supposed to go something like this: W from furnace (common, -0.7VDC ?) --> W on T-Stat 24 VAC power from transformer (+/- ?) --> C on T-Stat R from furnace (+0.7VDC ?) --> RH on T-Stat 24VAC power from transformer (+/- ?) --> RH on T-Stat As you can see, I'm still a bit fuzzy on the details. Questions are below the fold! [more inside]

I just installed a digital thermostat for the evaporative cooler in our house. Works great, hi/lo, pump, fans, etc., but there is a very low buzzing coming from the thermostat when the evaporative cooler is running. When the thermostat is in "standby" (just showing the ambient temperature) it does not make any noises. It is definitely coming from the thermostat and not any nearby location. Any ideas why this is happening? A defective unit? Weird house wiring? Thanks!

This is pretty specific, but we have a new Lennox G61-MPP gas furnace and aren't all that happy with the thermostat the contractor installed for it (Pro1 IAQ). Does anyone have any experience with other thermostats compatible with this furnace? Should be able to provide 7 day schedule, advance recovery, and multi-stage heat calls. Thanks!

Help me settle an argument between my parents about central heating, please. My mother believes, for instance, that setting the thermostat for 75 degrees and cutting it off once it reaches 70 degrees will warm the house faster than if the thermostat were simply set to 70 degrees initially. My father thinks this is ridiculous. Who's right? [more inside]

Hi all, thanks in advance for the assist: This weekend I started running the A/C in the house (we put in a programmable thermostat last summer). the prob. we are having is that it runs constantly no matter what temp. you set it to (my wife set it to 90 last night as we were going to bed and it continued running until I gave in and turned the whole thing off). the previous night I turned it on, with the temp. setting high (mid 80's) and went to sleep and we woke up freezing in the AM. the fan is set to Auto, and nothing about our "setup" has changed since last summer. Except that it doesn't stop running when it gets to the set temp. Thanks again for any help or insight the community might have.

Replacing the old mercury thermostat in our old house with a programmable one for an oil furnace. The old one is a two wire hook up, one red/white and the other black. What would be the correct configuration to the new thermostat? Black to R, Red/White to W? I've searched high and low for the answer.

Why are we comfortable with the thermostat set at 70 (Fahrenheit) in winter for heater, but we would be cold if it was set that low for the air conditioner in summer? Also, in winter here in SW Fla., on days it's warmer outside than what the thermostat is set on, my husband turns the heat off and opens the house, and then the temperature inside drops. Same thing in summer - if it's cooler outside he turns the air off, opens up, and the temperature inside goes high. He says the heat/air won't come on when it's nicer outside. I say that's the thermostat's job - to keep the inside temperature steady regardless of what's happening outside. Who's right?
