What is a common wire connection?
A common wire (C-Wire) provides Wi-Fi thermostats continuous power by connecting it to a heating and cooling system (e.g. furnace). C-Wires are required on most Honeywell Wi-Fi thermostats, with the exception of the Smart Round Thermostat (formerly known as the Lyric Round).
What are W1 and W2 wires?
In a conventional system, W/W1 controls your heating system and, where applicable, W2 controls your heating system’s second stage, which helps warm the home faster.
Is RC the same as C wire?
Though it is a common notion, it may be incorrect to state that the C-wire powers the thermostat. Typically, the wires that give the power supply (usually termed as the ‘hot’ wires) are marked Rc (for cooling) and Rh (for heating). ‘ If your system has a common wire, it will be marked ‘C’ at most times.
Can two wires be connected to one terminal?
Never connect more than one wire under a single screw terminal. It’s also not a good idea to direct-wire all three cables to the receptacle by utilizing both the screw terminals and the push-in terminals on the back of the device.
What is a W2 wire?
W2 – This is the terminal used for second stage heat. There are gas furnaces with low fire and high fire and some depend on control from a two-stage heating thermostat with a W2 terminal. G – This is the terminal used for the fan relay to energize the indoor blower fan.
