    Changing from LR69071 to RTH6300B thermostat
    My old thermostat (LR69071) has two wires only connected, a red and white, while three others (blue, yellow and green) were capped off. When installing the new 5-2 Programmable thermostat (RTH6300B), what would be the proper installation of the wires.
