Hi,

Here is a list of each common terminal and what their commonly used for. Also listed is what colors are commonly used. NEVER ASSUME these are what you have. Verify all your wires by following each to each piece of equipment. This will help you to be able to match your equipment with the terminal.

Here is the rest of the tip that I wrote...

How to change oven sensor


How do you know it is a sensor problem? If you know. usually there will be instructions with thepart. http://www.amazon.com/12001676-Admiral-Aftermarket-Terminal-Receptacle/dp/B00IFA6TZW This part is the connection between the burner and power to the burner by way of the oven thermostat. It is not a sensor connected to the thermostat. The thermostat sensor is the long tube usually on the side of the oven. it has a small tube that connects to the oven thermostat. So if you have determined that the issue is the sensor or thermostat you will need a complete thermostat and the sensor I described. Some appliance parts dealers will help you if you have problems. I assume your existing part has burned and you get no voltage at the outlet? Usually the connection you cite is behind the plate holding the burner to the back of the oven. So you will need to remove the burner which will expose the connection the rest is just careful connection of wires usually by screws for the wires.

I am wiring a Honeywell wifi unit and I used a separate 24v transformer and connected to the c and rc terminal. My system is ac and heat and uses both and rc and rh wire. I wired the rc to the r ter


A thermostat is a switch. It connects 24vac from one terminal to another depending on the request. The 24vac comes from a transformer, usually located in the furnace and connects to the R terminal. Since you are using RH and RC without a jumper between it means there are two transformers, one in the furnace for heating (RH) and one in the air conditioner condenser used for cooling (RC).
Your old thermostat was probably mechanical and did not have a C (24vac common) terminal. Your new thermostat requires power to operate therefore needs a wire connected to a C terminal. I would get rid of the transformer you added and look for an unused wire in the bunch at the thermostat. If it's there connect it to C on the thermostat and to C on the furnace. Remove any jumper from R to RC or from RH to RC depending on your thermostat and connect wires same as the old thermostat.

No heat after installing honeywell thermostat H8110U


hook up the blue wire in the furnace cabinet where the blower section and the other thermostat wires are connected to the furnace. the thermostat you have uses a common wire from the thermostat to the furnace and this needs to be hooked up in the furnace otherwise you will have the problem you are having.

How do you install a 2 wire heat only honeywell thermostat?


TURN THE POWER OFF. You need to be sure that the thermostat is made for the control voltage of your furnace. If the new thermostat has mercury contacts it has to be level to be accurate. One wire would be connected to the R terminal of the thermostat sub base and the other wire would be connected to the W terminal on the thermostat sub base. Seal up the hole in the wall where the wires pull through so cold air does not effect the thermostat. If the thermostat has an adjustable heat anticipator you will need to check the amp draw through the thermostat to set the anticipator properly. If you do not have an amp meter I would start out at a .4 amp setting and see how the thermostat cycles.

I have a honeywell thermostat model # th5220d1003-0636 & need to know what connections to make for gas forced air heat.


This is a Focus Pro 2 heat,2 cool thermostat. If you are connecting this to a single stage(1 heat) residential furnace then your connections are: At the thermostat the R and Rc therminals are internally connected so you can connect your R terminal wire from the furnace to the R terminal at the thermostat(this is your 24 volt supply for both heating and cooling. The W or W1 wire (heating) from your furnace you connect to the W1 terminal at the thermostat. The W2 wire from your furnace(if your furnace is a 2 stage furnace) you connect to the W2 terminal at the thermostat. The G wire from your furnace(indoor fan) you connect to the G terminal at the thermostat. The Y1 wire(cooling) from your furnace you connect to the Y1 terminal at the thermostat. The C wire(common or neutral) from the furnace you connect to the C terminal at the thermostat.

How do i change a thermostat??


buy the correct thermostat and thermostat gasket for your car, then locate the upper radiator hose. Where the upper hose connects to the engine there should be a two bolt hose connection/ thermostat housing ( could be 3 or 4 bolt, but most are 2) these bolts should be removed and then gently lift the hose and hose connection/thermostat housing exposing the old thermostat. note the position then replace the new thermostat just as the old was installed.
