Connect Nest to Three Speed Fan Controller in HVAC air handler

06-04-2024
Hi there I am working with a client installing a new air handler with connections for G1, G2 and G3 wires. Where do I attach the G2 and G3 wires on the base of the nest learning thermostat to implement the control for the fan speed?
