Mark all wires from old thermostat, then attatch to new thermostat with matching numbers. If they don’t have matching numbers, then go to http://www.honeywell.com and they will probably have instructions for that thermostat on their website.
you have 4 wires. red, yellow, blue and maybe green. i did some wiring last week and 3 of the 4 colors matched. just attach the odd color to the one that doesn’t have a match. if your thermostat has a 5th terminal. use a jumper and attach it to the red. the red should be next to the 5th jumper. select this as best answer.
