It is likely the orange wire but I have seen others use the blue wire in Rheem and Ruuds. I travel a lot and can turn things on and off from afar. A surface ceiling light is shown by one symbol, a recessed ceiling light has a various icon, as well as a surface fluorescent light has one more symbol. The less humidity in the air the cooler you will feel. This is why I told you the wire colors need to be absolutely determined correct by someone who knows what they are looking at lest you blow a transformer.
Thanks I would go to the transformer and disconnect everything on the control side and test the voltage. For example, a surface ceiling light is shown by one symbol, a recessed ceiling light has a various sign, and a surface area fluorescent light has an additional sign. A wiring diagram is a basic graph of the physical connections as well as physical format of an electrical system or circuit. Lastly, the outside air temperature sensor needs to have two wires terminated at S1 and S2 and are dedicated directly to a thermistor located outside somewhere. Units must be installed outdoors. If so, then have them come out and give the system a once over check.
If it is loose in the air handler and not connected to anything then connect it to the common side of the transformer or terminal board in the air handler. Since you have 5 wires I would go with an 18-7 conductor wire to give you extra wires in the future. Can you possible tell me how these relate to the normal designations? For instance, a switch will certainly be a break in the line with a line at an angle to the cable, just like a light switch you can flip on and also off. You are a stand up guy!!! I just bought this home 4 months ago when the snow was still on the ground. The yellow terminal on the furnace circuit board is not being used. Do not forget to share and love our reference to help further develop our website.
I have just about all my tools and ready to work. Do It Yourself fanatics use circuitry representations but they are likewise usual in residence building and also automobile repair. From what I have read in the Honeywell installation guide. Many systems only have a single compressor but if you have two compressors or a two stage compressor which should only operate off of one then you need the Y2 thermostat terminal for second stage cooling. To be absolutely sure you need to trace out the wires to see exactly where they go in the air handler and the condenser.
Oh, and check your main wiring schematic before hiring someone to hook up your thermostat. Wrap it around the bundle and wire as instructed. Will I blow anything up? Roadmaps and wiring diagrams have a great deal in common in that they both rely on the use of symbols and have a legend that explains what the most important symbols represent. Can I simply match new wire colors from unit to new t-stat and remove Add-a-Wire setup? Circuit boards or printed circuit boards found in modern systems utilize 24-volt control which originates from the control transformer. Simply add a wire under the C terminal in the air handler. I am under the impression that the voltage between the red and blue common should be continuous at 24 volts or more.
Typical systems that do not use 24-volt control are window unit air conditioners, ductless mini split systems, and baseboard electric heating systems. Keywords for York Hvac Wiring Diagrams :. Additionally, the existing wire you are talking about will not work on the Honeywell thermostat. It is likely you have a simple R terminal at the thermostat and that is where the red wire should be terminated. I sure there are sequencers to control the staging though. The thermostat is battery powered rather than powered from the control transformer.
You are dealing with high voltage you know and it is potentially dangerous. Based in Colorado Springs, Colo. For the thermostat wiring colors code for this terminal if equipped consult with the installer. Typically a thermostat wire pull is made to the air handler on split systems. You need 7 wires from your description but the bundle has 8 wires. The fix could be something very simple or it could something very complex. Attach that wire to the C terminal at both the new thermostat and the control board.
