From your description it appears the old thermostat used batteries and had no common connected.

W - white wire - this wire goes to the gas controls to engage the heat on a call for heat from the thermostat when you have it set to heating mode. This function allows you to circulate the air in the house by using the fan in the furnace without heating or cooling the air moving through the system. You already have the 24 volt hot with the red wire so now you need to either find another wire in that bundle or run all new thermostat wire so you will have the proper amount of wires for the job.
Any idea why or what this means? Now the thermostat is red to the transformer white to white. I travel a lot and can turn things on and off from afar. On a split system the blower fan is in the air handler. Most people do not and they end up calling in a professional to get the job done. In either case, it is important to find the wiring diagram for the unit. Just curious, why is G wire going to the C terminal on the thermostat? Simple one-stage furnace control system. That could potentially cost you a service call for troubleshooting and repair.
Your thermostat does not have that terminal. This wire goes to outside heat pump condenser where the reversing valve is located. The inspector recommended having the furnace cleaned since he noticed a few things. Someone got into the furnace and messed with the wiring. There are with low fire and high fire and some depend on control from a thermostat with a W2 terminal. The number of 240 volt circuits required for the heating elements will depend on the quantity of heating elements that are installed and how they are configured or prewired from the factory. It is really important to know this information.
This closes the 24-volt control side of the gas furnace and begins the process of Y - blue wire — This wire goes to your air conditioner and starts the. R to C on Board kicks on great. There is a 24v transformer, a timer, a relay and the blower motor. Most likely it is old wire and the insulation has worn off and the copper is touching from one color to the next or someone drove a nail in the wall and hit the thermostat wire creating a connection where the nail is. I replaced the blower capacitor because the blower failed in the middle of the night. If your circuit wiring has a spare white neutral wire and your furnace specifications does not require a neutral wire then cap off the white neutral wire as a spare wire and do not attach it to the ground terminal.
I sure there are sequencers to control the staging though. I don't know the make or model. E — This terminal is for heat pumps and stands for Emergency Heating. I am attaching a picture of what we do have. I replaced the thermostat and discovered that the Green fan wire is Not connected to anything on the air conditioner. You're correct, that T wire is your C terminal.
As for the T wire, I think that it is the same as the C wire because the furnace has no C terminal. Thank you for your diligence in looking this up George. This made the unit run properly. I also sense that the reason the black wires are connected is so that the blower motor in the furnace can turn on when cooling is turned on. Always make sure there is no voltage at the transformer before proceeding.
We have been hunting for this image throughout net and it came from reliable source. Is it a heat pump or is it just a straight air conditioner? Thank you so much and look forward to hearing back! You are 1 wire short. In this the most basic of heating systems, as the temperature of the heat exchanger rises, another contact is closed on the line voltage side of the equation, and the fan blower motor starts moving air through the heat exchanger and out through the ducting in the home. Many digital thermostats require 24 volts for power so the common wire is necessary. This should help get you going. This will provide the necessary overload protection for the circuit wiring and internal furnace components that are part of that 30 amp circuit.
E — There is no universal color used for this terminal designation but this should be wired directly to the heating relay or the E terminal on a terminal strip board in the air handler or package unit if you have a heat pump package unit. Now that its finally getting hot, I turn the air on and nothing worked. This board as I said above does have a common which if I plug wires from contactor into R and C, it works But I cant get it to communicate with the T-Stat correctly I am assuming since this has no C at all? How would I do that. If you follow the wire from the R-terminal it should go directly back to the transformer. You can do this at the air handler and condenser. Furnace end terminal Thermostat end labels R R Red electrical tape G G should be fan W W should be heat T Y not sure Y - no connection Here is a picture of the wiring on the thermostat end: Here is a picture of the furnace end. You can email ecobbee support and wait for a reply or ask the agent for an email while you talking to them.
