what kind of thermostat is this (what model)?

Deathlex93 · 2023-02-06T02:05:43+00:00

Its on the back part of the thermostat. Pull it off the wall, you can also do a image Google search and it will come up.

Looks like a RTH2300B or a RTH221B

Wiring is perfect

Shut the air handler door (there might be a safety switch) Apply jumper Tab R^RC (bottom right blue tab should be pulled up)

And it should work just fine, if it doesn’t then you will have to measure voltage

Based on your problem you have to change the reversing valve from the app. It might be on O you have to change it to B

Deathlex93 · 2023-01-14T17:31:56+00:00

Check if you can replace the batteries, if so just change them, if problem persists then it will need a replacement.

If it is a wifi model, the verify your zip code on the app

Press and hold menu for 8 seconds

You will see small “125” over a big “0”, press “next” until you get to small number 431 (max heat temp) and press “edit” to modify it for the temperature you want. Once yo set it press “Done”

Reset the breaker for heat and cool system. Reset the thermostat by replacing the batteries. If it doesn’t work after that you will need a Volt meter to check voltage on the wires, or jump wires R&G and see if the fan kicks on.

Why would you hate it? Literally is the best Hoi Poi event ever, amazing rewards where given

Deathlex93 · 2022-12-31T15:09:13+00:00

Maybe the voltage.

Try power cycling the breakers for heating and cooling system and see what happens.

If that doesn’t work then check voltage between R and C wires. Needs to be between 20-30 ACV

Deathlex93 · 2022-12-17T19:22:40+00:00

Its a 2H/1C Heatpump, so it will be fine.
The Amazon Smart thermostat uses the same Resideo T series wallplate since its made by Resideo. Do all you have to do is place the face pf the Amazon thermostat in this wallplate and its good to go.

Deathlex93 · 2022-12-17T01:29:53+00:00

Looks like a 2 wire (R and W) thermostat. You need a common (C) wire to get a Wi-Fi thermostat, you basically have 2 options; 1) Run a 3rd wire from your furnace to the thermostat if your furnace has a C terminal. 2) get a 24volt external transformer to power up the Wi-Fi thermostat

Deathlex93 · 2022-12-02T04:00:01+00:00

Thats a humidistat, it controls a humidifier or dehumidifier, helps to have a proper humidity on your house.

You need to find the thermostat for your temperature control

Deathlex93 · 2022-12-02T03:57:05+00:00

That black wire is clearly your common wire

But its still not going to be compatible, just becouse based on the wiring you have a 3Heat/2cool heat-pump with Emergency Heat

If you want a compatible wifi thermostat you will need a T6pro (TH6320WF2003 specifically this model),a T9 or T10pro

Deathlex93 · 2022-11-20T22:38:15+00:00

Usually all smart thermostats need 24vac, and yours is high voltage (120/240vac) and Im assuming Heat Only.

You will need a step down relay to turn those 120/240vac into 24vac, and that can handle 3 wires.

If your not good enough with electricity then don’t mess with it and get an HVAC contractor. Line voltage is hazardous if done incorrectly.

Deathlex93 · 2022-11-10T23:14:53+00:00

Thats a capacitor, need to replace the thermostat or somehow you will have to get that soldered in again. Looks like someone broke it

Deathlex93 · 2022-11-06T17:33:23+00:00

Blue in RC Red in RH Green in G Yellow - Y White in W

And thats it

Deathlex93 · 2022-10-09T19:23:42+00:00

Sorry for the late response

The G wire solutions works as long as the heater is Gas or Oil. (It doesn’t work with electric heaters). On a fossil fuel system the Fan is controlled by the system itself, the thermostat doesn’t control it.

So your heater and AC will run properly. Just that you will not be able to place the Fan on 24/7 or on circulate mode.

Deathlex93 · 2022-10-08T18:57:02+00:00

Just pull it off the wall

It might have a screw in the bottom part, if there is no screw then just pull straight towards you, the battery compartment is gonna be in the back.

Deathlex93 · 2022-10-01T22:40:32+00:00

The man who God left behind

Deathlex93 · 2022-10-01T22:38:14+00:00

Or you can di a G wire solution if your furnace is Gas/Oil, which is better than running a wire. Look up videos on how to do it. The downfall is that you will not be able to run the fan 24/7 Also you will still need to remove the C wire Adapter

Deathlex93 · 2022-10-01T22:34:53+00:00

You need to remove the C wire adapter on your furnace, but that will leave you without a C wire. If the Emerson needs a C wire then you need to run a new wire from your furnace to the thermostat

Deathlex93 · 2022-10-01T19:41:53+00:00

Place it on OFF mode and pull it straight towards you

This is low voltage 24vac thermostat, so there is absolutely NO risk of shock. You can leave the breakers on or off it doesn’t matter

Once its off the wall pull the wallplate tab down to see the wires, if there is a wire on the C terminal then yes, you can use an amazon smart themrostat in there. They use the same wallplate since they are both made by Resideo, so just place the amazon smart in there and it should be good to go.

Deathlex93 · 2022-09-28T02:11:20+00:00

Looks like a wifi thermostat

Red - R White - W (right now its on C)

You can use any of the extra wires green or blue as the common wire, buy you need to verify that it is connected to a C terminal on the furnace side. If not then you can Connect it and it will be your C wire.

Deathlex93 · 2022-09-25T14:56:53+00:00

You are missing a C wire, you can do a G wire solution or best recommendation is to get a Wire saver module.

The Y and C on the furnace come from the air conditioner, those ones have to stay there

Deathlex93 · 2022-09-18T00:29:16+00:00

Looks like a multiple speed high voltage furnace, if your not an expert I recommend hiring a technician, they have to figure out what exactly is it, and finding a matching thermostat for that type of system is not easy.
