The “c-wire” as it’s called is a control wire that provides a constant flow of electricity to the thermostat to aid in its several functions
It’s simple to make the wrong assumptions about device and technology when you’re trying to hook up 2 machines together that may or may not be compatible. I l earned this lesson in the 90s with my video game systems. Unless you owned an adapter love I did, you couldn’t link several game systems to old TVs that only had coaxial linkions in the back. This is because the game consoles used RCA cables with the red, white, and yellow wires. My dad is an electrician so she constantly had the respected audio and video equipment, parts, and accessories. Every one of us would plug the RCA linkions into the adapter which would convert the signal to a coaxial linkion for the back of the old cable we had in the residing room at the time. Luckily, there was an available conversion adapter available. With some machines, you might not be so blessed. My buddy John desperately wanted a smart thermostat for her home’s Heating and Air Conditioning plan after she used the a single her mother bought for her beach condo. Unblessedly, John’s old Heating and Air Conditioning plan lacked a necessary wire that you must have for smart thermostats to function respectfully. The “c-wire” as it’s called is a control wire that provides a constant flow of electricity to the thermostat to aid in its several functions. Other digital thermostats often contain a battery love a 9-volt or 2 double AAs to power itself. John will have to get her setup modified before she can purchase a smart thermostat for her central Heating and Air Conditioning system. He’s looking for quotes from several Heating and Air Conditioning dealers before she makes her final decision.
