Honeywell Steam humidifier: HM 505A 1000/000247
Problem: New installation, and there are no terminals ABCD to hook up to the wireless adapter THM4000R1000. Apparently HW makes two or more versions of the circuit board, and my model happens to be the one doesn't support wireless.
It's a long story. The contractor who did the install left the job 6 months ago and is unresponsive. I have contacted HW to see if I can buy the circuit board that supports the wireless and they didn't have a clue about what I was talking about.
The existing circuit board is # 98100140000247.
From what I can tell it seems I need the circuit board from HM506W1005
Is there anyone that can help me identify the part number for the correct circuit board from HM506W1005? And further can you tell me where to purchase this Honeywell part?
Thanks for the help.
