Hi, I was searching the forums trying to see what i need to do do change over my humidifier. I can't seem to find the answer so i thought I'd make this post. I have a high efficiency furnace, i had one of those old drum humidifiers that did nothing but leak on me. So i disconnected it a while back and just purchases a Honeywell Flow Through humidifier. My question is, to do a swap, is it as simple as removing the old one and just putting this new one in?? the honeywell came with an instruction DVD i'm a little confused on this sensor. seeing I am just replacing this one with the new honeywell, can i reuse all the wiring, etc?? If anyone has any advice or tips, please let me know. Thanks in advance.
