Trane XV90 furnace and Honeywell 24V Humidifier? - honeywell humidifier parts

I have a gas stove manufactured by Trane XV90 and try to connect 24V Humidifiers Honeywell. My circuit does not seem to 110 V common HUM, do not occur in the hot connection. I was the main telephone wire, but in tests, HUM Circut N is open, even when the heat / fan is turned off. I would like to humidfier only when running the heat / fan. I could connect with the son of the thermostat (B / C), but I have a message that the system could be damaged. What is the best way to son, and why have a common connection Hum?
