thermostat wiring

in THE MAIN WALL
i just replace an OLD thermostat with a Honeywell programmable. the old wires were black so i could not trace them to the basement to see were they went. this is a two wire system (just one hot water boiler on the thermo). i called my supplier who said that as long as one is connected to Rh and one is connected to w then it doesn't matter which wire is which. i just wanted to make sure that that is accurate. thanks

    T-stat

    Should be okay. 2 wires T-stat is just a switch that opens and closes on temperature.
