One of the more frustrating items for a heating/cooling system is the sheer number of possible ways to set it up. Sure, there are "standard" ways, but there are also always other ways. We had a new furnace installed not long ago. However, there were not enough wires run to the thermostat to support the additional A/C system. The cable had only enough wires for heat-only operation. To make it work, the installers should have run a new cable, but they didn't. Instead, they disconnected the G (fan) wire, and used it for Y (cold call) instead. This led to an atypical installation that lacked a G (fan) wire at the thermostat. Note it still worked. The thermostat sent the W (heat) and Y (cold) signals, and the furnace controlled its own fan.
