    So I'm a DIYer renovating my house with a tricky thermostat wiring issue that I KNOW should be theoretically possible, but I'm having difficulty figuring out the last steps. For Context: My house is a single story manufactured home that has forced air heating and cooling. I replaced the...

    So, we finally got around to running new wire from the thermostat to the furnace. We're installing an Ecobee4, which requires a common wire, but we decided on running new 5-wire cable, just in case. Anyways, there's no labels on my furnace and we have no idea how to connect the new wiring. I...

    I just installed a new programmable thermostat on my Carrier heatpump (25HBC342A300) and I think I blew a fuse, but not sure. I installed it color for color like the old nonprog one, except the black wire was in the C terminal, now it's in the B (g, w, y, r). I have 3 thermostats (3 zones I...

    Hello, I'm replacing an old mercury thermostat from 1959 that has three wires: Red - 4 White - 5 Green - 6 / Y Only the green wire was connected to a letter/number, the rest were just attached to numbers. This thermostat is connected to a boiler only that heats the house using baseboard...

    I went away for 6 days, so I turned off my thermostat when I left to help save on energy costs (I now know to just turn it up rather than off). When I got home and turned the thermostat back on, the AC would not work. By not work I mean the unit blows air, just not cold air, and it doesn't blow...

    OK, here is the issue I have. I have two zones for my heat/ac. I have an oil boiler, an a/c unit outside and what i believe to be hydro heat as well (there are copper pipes that run through the forced air portion of the blower). One zone (main floor) has a nice programmable LUX thermostat...

The furnace has the following terminals on it, C, G, R, Y, W1 & W2. The W1 & W2 terminals in the furnace/ac unit were jumpered together, I...

    For the past month I have been trying to figure out why my Climatemaster TTS 5 ton split system has not operated up to expectations, or specs. We were happy with the performance when we turned it on back in mid October and up until the cold snap before Christmas. Something happened and the...

    I have a south facing greenhouse attached to the side of my home here in Central Arizona. When I built the house I brought duct work in the floor over to the wall next to the greenhouse with the intention of scavenging heat out of the greenhouse in the winter time. The heat in the green house...

    I recently replaced my AC myself (condenser unit, coil, lineset only) and wanted to update and replace some of my other 15 years old equipment. I have a weathermaker 8000 Two Speed, forced air gas furnace. Its rated at 80,000btu output on high. My thermostat is a honeywell but not sure of the...

    I made the mistake of thinking a baseboard heater had an intermal thermostat or control board that I could hook up to a remote low voltage thermostat. I have 220 to the heater, plus a low voltage thermostat wire. I was browsing around the internet last week and found something that would work...

    Hi, I just purchased a home (approx. 1 year old) which has the dial-type Honeywell thermostats installed. I've noticed on the majority of them, that when they turn on, there is a buzzing / vibration noise that lasts for 30 seconds or so. If I happen to touch the dial part of the thermostat...

    Due to a complicated situation I won't go into, I would like to prevent the heat from going above 68 degrees in our house. I know this probably isn't possible without a lock box, but I was wondering if I could change the thermometer to read a higher temperature by insulating it more? I don't...
