New construction or retrofit
When constructing a new home, you have the luxury of being able to wire for now and the future. If retrofitting, you may need to relocate your distribution panel to a location where it will be easy to feed additional wires to other locations in your home. Either way, you want to make sure you have a good understanding of your home automation needs to wire for communication, entertainment and security.
We suggest the following:
- Develop a plan that will support your home automation program needs now and years into the future.
- Know which devices you will need hard-wired, requiring an Ethernet cable, and those that can work wireless.
- Consider outlets, light switches, hvac and entertainment needs.
- Don't forget the common or C wire. This is typically required for successful powering of most smart thermostat models.
A skilled, professional electrician should be able to help advise wiring options specifically for your needs.
Don't forget the common wire
Common wire, or C wire, is not typically found in homes. Your home may have 4 wires: G wire (fan), R wire (power), W wire (heat), and Y wire (air conditioning).
The C wire is a fifth wire that enables the continuous flow of 24 VAC power to the thermostat to keep it running, working in conjunction with the R wire. Most smart thermostats need this power, other thermostats typically run on battery.
The common color standards for wires are:
- Blue or Black –C, this is the common wire
- Red – R – power
- Green – G – fan
- White – W – heat
- Yellow – Y – air conditioner
