    Your heat anticipator which is located on your thermostat has to set to the total amp draw of the heating circuit when he changed the valve the amp draw changed he should have set it then

    If the new valve was the same part as the old one, I doubt it would have thrown the heat anticipator off that much. It sounds to me like you have a bad temperature sensor, or if an older furnace, a limit switch.
