Typically if you are replacing a heat only thermostat you will have two or three wires. On the old thermostat these wires will be attached to terminals marked "R", "W" and maybe "G". Document what color wires goes to which terminal and transpose these to the new thermostat. If you have a heat and cool thermostat, you will have two or three more wires and connected to terminals labeled "C", "B" and "Y". Again, transpose these wires to the new thermostat as best you can.
