the first one has worked fine for 2 years. My house is 100 years old, and the one I just replaced has three wires coming out of the wall--red, white, green. The green was not hooked up, as I have no fan system (oil-fired boiler), just heat. I never turned off the power to hook up the new thermostat......when I installed it as instructed, I can't get the boiler to fire when I raise the temperature. The boiler still works--I can fire it with the other thermostat, but even when I switch the wires (which I had to try with the other one because they were not neatly color-coded), I can't get it to work. Please help!
