    Honeywell RTH7600 Battery Free Operation
    Hi, I successfully installed the RTH7600 on my 2 wire Weil McLain, hot water, cold start, gas fired system. I then tried to enable the battery free function by running the system common wire (C on the 28vac transformer) to the "C" terminal on the thermostat. This did not work. Should the common go to a different terminal?
