Humidifiers and Dehumidifiers - Install HE220 to Rheem M0799

I installed the Honeywell humidifier to my Rheem. I little time consuming cutting through the duct work, but it all looked good.

Reading the fabulous responses from Jay, I was able to figure out the wiring. My electrical board appears to be 24v; so I didn't need the solenoid. I went from the board (red wire) straight to the humidistat. I took the white wire from the board to the humidifier, then took the second wire from the humidier and attached it back to the white wire and took the white wire to the humidistat.

I connected the white wire to the "Common" and the red wire to the EAC. My board does not have a Humidifier "HUM" connection. I checked the manual. Very disppointed.

When I turned everything back on, the humidifier made a *click* and water started pouring down the humidifer. SCORE!.

Here's my challenge. I went to bed last night, woke up and checked eveything out with the heater on. No water. The humidifier was set at 40%. I moved it down to 20% and heard the small *click* in the humidistat as it was triggering the mechanism to turn off (I presume). I turned it back up to 40% and heard it *click* to turn back on. But again, no water coming out.

I turned off the heater; waited 5 minutes, and turned it back on. I never heard the louder *click* on the humidifier. No water. Bone dry.

Any ideas?

This is a great message board, and the responses from Jay are invaluable. I'm surprised Honeywell doesn't take advantage of reading this stuff to revamp their included instructions.

Thanks.

I just checked the voltage coming out of the eletronic board under EAC, and it's at 120v. So am I assuming that's too much power? Is that my problem?

I am afraid you have fried the valve.. It only needs 24 volts. and the transformer is needed.
