I recently bought a programable thermostat, which has 5 connectors. I asked the handyman to install. He has all the wires in the furnace area loose, and we don't know how to re connect.
The thermostat has 5 lugs RC RH Y W G

There are 2 wires coming in from the outside A/C, and they are RED WHITE

The heat has 4 wires RED WHITE GREEN BLUE

what is the correct way to wire??

thank you.
