depends on whether thermo used on gas or elec. unit, heat pump, strip heat, etc.
red wire is hot wire.
White wire goes to heat.
yellow wire goes to outdoor unit contactor.
green wire goes to indoor fan.
blue or brown wire goes to reversing valve on outdoor unit.
That Thermostat is LOW voltage. IT does not have a ground wire. There is no need for a ground. it only opperates on 24 volts. there may be a green wire but it does not mean it is a ground
There is either a problem with the downstairs thermostat, or the wiring from that thermostat to the unit. First check the batteries in the thermostat. Yes the digital ones have batteries. :-) Next, if that doesn;t fix it, try switching your two thermostats. Be careful to wire them exactly as they were before. If your heat now works downstairs and not upstairs, replace the thermostat. If the problem remains unchanged and you still have heat up and not down - check your thermostat wiring. The voltage is low so a simple voltmeter can be used to confirm continuity from the end where it goes into the furnace to the end where it connects to the thermostat. If the wire checks out and the problem is not the thermostat, then call a licnesed professinal - youhave bigger problems.
Okay - it's going to be difficult to do an accurate diagram on here - so bear with me...An electromagnet consists basically of a piece of metal surrounded by a coil of wire, which is connected to a power source. The simplest form would be an iron rod which has a piece of wire wrapped around it (about ten) coils should do it. The ends of the wire are attached to a 9 volt battery.Ignore the dots in the following diagram - they're just to stop the spaces being removed by the forum !...____|+ -|____| ................... || ................... ||___/\/\/\____|It's a bit crude - but I think it's understandable. Basically, you connect the battery (+ -) with a continuous piece of wire. Wrap the wire around an iron rod - the '/\/\/\'. This induces a current in the rod, while the power is connected.

To check if the wires of a dishwasher are grounded, first ensure the appliance is unplugged or the circuit breaker is turned off. Use a multimeter to measure the voltage between the ground wire and a known live wire; if the reading shows voltage, the grounding is likely intact. Additionally, inspect the grounding wire connections to ensure they are secure and properly attached. If you're uncertain, it's best to consult a licensed electrician for a thorough inspection.
I was a soldier so I dealt with both types alot. Constantina wire has sharp little squares where as razor wire has bigger razor blade shaped barbs.
To install a Honeywell thermostat without a C wire, you can use a power extender kit or a smart thermostat that doesn't require a C wire. These options provide alternative power sources for the thermostat to function properly without the need for a C wire.
The two wire thermostat wiring diagram for this model involves connecting one wire to the R terminal and the other wire to the W terminal.
To properly wire a 2-stage thermostat for your heating and cooling system, you will need to connect the wires from the thermostat to the corresponding terminals on your HVAC system. Make sure to follow the wiring diagram provided by the thermostat manufacturer and consult a professional if you are unsure.
The Nest thermostat wire diagram for installation typically includes labels for wires like R, C, Y, G, W, and Rh. These wires correspond to the connections on your HVAC system and help guide you in properly installing the thermostat for optimal performance.
The 2 wire thermostat wiring diagram for a specific model of thermostat typically involves connecting one wire to the R terminal and the other wire to the W terminal on the thermostat. This allows the thermostat to control the heating system.
A thermostat C wire diagram shows how to connect the C wire for proper installation. It is important for providing power to the thermostat. You can find these diagrams online or in the thermostat's manual.
To install an ecobee thermostat without a C wire, you can use a power extender kit provided by ecobee. This kit allows the thermostat to be powered by the existing wires without the need for a C wire. Simply follow the instructions provided with the kit to install the thermostat properly.
To properly wire a thermostat to a furnace, you need to first turn off the power to the furnace. Then, connect the thermostat wires to the corresponding terminals on the furnace control board. Make sure to follow the wiring diagram provided with the thermostat and furnace. Finally, turn the power back on and test the thermostat to ensure it is working correctly.
To install a Honeywell WiFi thermostat without a C wire, you can use an external power adapter or a power extender kit to provide the necessary power. These devices can be connected to your HVAC system to ensure the thermostat functions properly without a C wire.
Yes, a C-wire is typically needed for a furnace to function properly, as it provides a continuous source of power to the thermostat. Without a C-wire, the thermostat may not work correctly or may cause issues with the furnace's operation.
A 6 wire thermostat wiring diagram is a guide that shows how to connect the six wires from the thermostat to the heating and cooling system for proper installation and setup. It is important to follow the diagram carefully to ensure the thermostat functions correctly.
In a 2-wire thermostat wiring diagram for heat-only systems, one wire connects to the R terminal on the thermostat and the other wire connects to the W terminal. This setup allows the thermostat to control the heating system by sending signals to turn it on or off.
