I am about to wire my WYZE Thermostat and need some guidance before I screw things up.
First of all, my 30-year-old Honeywell thermostat only has 4 wires: R G Y W
My equally-old gas furnace has 5 wires: R G Y W C
I presume I need to use the C-Wire Adapter at the furnace. And other posters said you need to move the G wire in the thermostat to the C-wire terminal. Is this correct? What do I do with the C wire that’s already attached at the furnace?
