I replaced our older unit a couple of years ago.

All it really took was turning off the breaker controlling the unit, then swapping thermostats.

The instructions that come with the new thermostat will have wiring charts- ie, if your wires are brown, yellow, red, and blue, then connect brown to the screw marked '1', the yellow to the screw marked '2'. If your wire colors are red, black, blue, and brown, then connect red to '1', etc etc etc.

It's definitely DIY-able in most cases.
