Question about Heating & Cooling
Did you shut the power off to the furnace before you changed the stat? If you didn't then you could of tripped the cicruit breaker on the transformer or fuse or you could of shorted out the transformer. I would check for voltage between R and C on the control board to see if the transformer is working.You should have 24 volts AC.
recheck your wiring on the stat. General guide go down to the furnace and write down what colored wires are hooked up on control board and match up to thermostat...
