Thermostats wiring
 

I have a 5 wire system and need help connecting a White Rodgers 80 Series 1F80-361 thermostat.The colors are white,red,green,blue and yellow.There are no markings on the wires so I don't know the hook-up.The unit is running
but when it get to the sitting,it won't shut off.This is the heat seting.Any ideas? :huh:
