Asked by Neil March 24, 2019Yes, just tuck those back into the box. That is the connection between the thermostat and the fan motor. If you want to get fancy, you can use a 3 conductor wire and a switch to connect in with that pigtail to bypass the thermostat. That way, if the switch is off, the fan come on as the thermostat requires, but if the switch is on then the fan runs continuously. note, there is also a green screw in the thermostat box for your ground wire connection.
