Great video! I have same set up. Only issue is I couldn’t tell where the wires came from your mess there ya unscrewed so fast. Love if ya could look at mine and tell me if it’s the same
Interesting. Obviously you're system is duelfuel. Would your furnace also be used for auxiliary heat? I live in California currently, where I was born, but grew up in Maryland and Michigan where both houses used heat pumps. To give a time reference, Maryland was in the 70s. Michigan from 1980 to my move to California in 1998. The house in Maryland was air sourced Michigan was water.
I have a Gen 1 Nest thermostat that i self installed to a circa 1994 York natural gas furnace and central AC unit. I just had everything replaced with a Bryant furnace and Mitsubishi heat pump. The installer removed my Nest and said the heatvpump has to use the basic (and dumb) thermostat from Mitsubishi. Can i use a Nest thermostat with this new heatpump setup? Doni need to upgrade to the most recent version?
great video i feel confident i can change mine out now. i was about to pay best buy $130 to do it. side note i had to pause the video at 3:49 to count the number of fingers you had.for some reason it looked like way too many lol
Curious on how it knew the outside temperature if you weren’t finished setting it up. Unless when you connected to Wi-Fi, you enter your zip off camera.
[hit the button too soon] a question to see if i got this well understood --> my house is a ranch, bosch combi-boiler that drives 2-zone baseboard heating, and a goodman heat pump with installed electrical resistance heat strip for forced air heat and cool. there are 3 NEST E thermostats. i 'think' the rules for the system might go like this: (1) each NEST E for a baseboard zone would be conventional 1 stage heating: W1, C, G, Rh., with heat to turn off when temp > 40deg; (2) the NEST E for the heat pump + electrical resistance heat strip would be 1 stage heat pump with aux heat and emergency heat: W2, C, G, Rc, *, with heat pump set to turn off with temp
Hello, I have a Bryant system with following model numbers. I also found wiring info. mentioned below. I am unable to tell which wire needs to go to Nest learning thermostat in order to get everything working again. I connected A to G, B to Y, C to OB, D to Rh. I dont see furnace working and I am not getting any heat. Is this something you can help me with? A-Green=DataA B-Yellow=DataB C-White=24VAC(Com) D-Red=24VAC(Hot) Bryant Furnace Model - 315AAV036070AGJA Bryant Heat pump Model - 288BNV024B00FA Display Model - SYSTXBBECCO1-A Thanks in advance for your time.
Is the Nest any smarter about aux heat on a heatpump? I have one of those Honeywell FocusPro thermostats and if I raise the temp by more than 1 degree it'll turn on the aux heat even if it's 50F outside. I added a switch in the white wire in the basement so the thermostat can't turn on the aux heat unless I turn that switch on. Incidentally, when it dropped to 6F overnight here, set point was 68F but indoor temp dropped to 64F due to no aux heat. I was OK with that. 15 SEER builder-grade Trane heatpump can keep my house at 64F when it's 6F outside not using any aux heat. I think that's pretty good. It's not so much the heatpump as it is that this house is pretty tightly constructed.
I have dual fuel system, heat pump with propane (gas) furnace backup. Looking at my connections I see my red wire is going to Rc instead of Rh. Is this something I need to correct? I see your red is going to Rh. Thanks
When a heat pump is in the defrost mode when in the heat mode it turns on the electric, heat strip and most heat pump arrangements. Centura doesn't have electric heat strips and you have a gas furnace. Does it do the same?.
I have a question ..how the nest thermostat .read .outside themperature .. .?? Right now .i have a goodman heat pump ..with a furnece ..i have a thermostat . Pro 8000 With outside temperature sensor Sensor is conected To s1. And s2 .
Like your vids because your in a similar area to me here in NW Pennsylvania. Could you do a vid on building a snow an ice protective in-closer for your heat pump?
i am doing A Mr cool natural gas furnace and mrcool universal heat pump. i hear its made by Lennox . watch at the 14:24 mark and tell me thats not the same as mrcool. Dual Fuel Heat Pump Install Tips - How To Install A Heat Pump by HVAC Know It All... any how HP- Y,R,C all connect to the furnace at R,Y,C the blue would feed though (wire nut it going to the thermostat) D is for defrost if your furnace supports it. if not omit it. now my heat pump needs power to the B terminal at the HP(heat pump) for the heat to work. your may be different and you need to know so you can set the nest to supply power or not depending on the mode desired ( heat or cool) and the B terminal from the HP connects to the O/B of the nest. after that these are all furnace terminals for a single stage furnace. R to Rc or Rh doesn't matter. the nest makes the connection between them. The reason for the separate Rc Rh as i understand it is if you have 2 transformers. 1 for heat and 1 for cooling. say a air handler for cooling and a boiler for heat. the 2 systems are separate from each other so 2 transformers .W to W1, C to C,G to G, Y to Y1 and of course R to Rc or Rh and HP B to O/B and if your furnace has a D then that to HP D if not omit it. I'm not saying wire colors because they differ from instal to instal.... easy peasy. if i am wrong please comment and correct me. i am not a hvac tech by any means . just a hack with a good understand of wiring. use at your own risk. and your system may very.

I owned this model of thermostat but ended up removing it after the thermostat began short cycling my HVAC. The issue was never truly fixed by the manufacturer. I would use the actual product and company names but it seems the AI mods are removing negative comments.
@@Ybeazzie That's one of several theories pertaining to this issue. Meanwhile, everyone affected had been long term Nest customers that all began reporting the problem following a specific software update. Nest refused to look at the code. Between this issue and Google's botched acquisition, moving to another platform was the easiest solution to my problem.
@@roberthernandez7564 man didn't want to hear that but ill definitely keep that in mind. i have read that with inverter / condensing? units you shouldn't use the self learning mode because it wi short cycle the systems and are less efficient. the units run constantly at low power and ramp up when called for. back to physics 101 once an object's in motion it's easier to keep it in motion. they inverter systems take a lot of power to start. more then a old style pump but once they are moving they use less power so you don't want to keep starting and stopping them. just let them run on low power.
I don’t understand how you know not to use the white wire like I’m just a nobody trying to install nest without having to pay somebody to come do it and I have a leftover white wire that went into the E plug on my Honeywell
No Nest thermostats have a mic but pretty much every other Nest product does. Thermostats with power stealing would have a lot of trouble staying charged if they were using a mic and uploading voice 24/7. Don't take my word for it - check out recent tear downs of the newer thermostats
I use a digital thermostat with no bells and Whistles. Those fancy thermostats have done nothing but give me grief. My bill so far has dropped by over $150/mo.
What about 'E' ?? I have a brown wire going to 'E' My system currently has C - BLUE O - ORANGE / W/E \ - BROWN \ W2 / - WHITE / RH \ - RED \ RC / G - GREEN Y - YELLOW
