If no green wire exists you may need to pull a new thermostat wire from the furnace to the thermostat.
How does a furnace with two thermostats work?
Each zone has its own thermostat that controls the heating and cooling operation in that area. The dampers and thermostats are connected to a central control panel that is also connected to the HVAC unit. This allows the unit to respond to requests from multiple thermostats.

How does a multi room thermostat work?
When multiple thermostats control one system, the house is divided into zones using dampers in the ductwork throughout the house. When one zone needs heating or cooling, the damper for the ductwork in that zone opens, guiding the warm or cool air to that zone.
