In respect to this, how does a 2 wire thermostat work?Most two-wire thermostats wire have a red and white wire encased in a brown insulated coating. Strip the red and white wires back about 1/4 inch at both the thermostat and the furnace ends. Connect the white wire to the “W” terminal on the furnace and thermostat.Also, can I use a 4 wire thermostat on a 2 wire system? Yes, you can connect a four wire thermostat to this setup. Connect the white wires in the same manner as the black wires are connected. Keeping this in view, can I use a Nest thermostat with only 2 wires? The Nest Thermostat is compatible with 2 wire low voltage HVAC systems that are either heat only systems or cooling only systems.How many wires does a thermostat need?In the most basic system, this functionality is provided by use of a fan center relay, and the low voltage wiring to the thermostat now will require a minimum of three wires (for heat only units) and four wires (for heat / cool / fan) for control.
