Question about Honeywell HE150A1005 TrueEASE 12 Gallon Advanced Bypass Evaporative Humidifier

1 Answer

The HE150 unit after hooking up flashes between the red and green light then shuts off. Brand new unit.

I also turned the % up to max but that did not make any difference.

Flashing red flight

Its probably the cleaning light that comes on periodically to remind you to clean the unit. Shut off the unit AND when you do so hold down the power button for several seconds until the flashing red light shuts off. The cleaning light should stay off until the next cleaning is due.

Per the Air-O-Swiss FAQ:

Q: Cleaning light is flashing (AOS U650, AOS 7135, AOS 7142, AOS 7144, AOS 7147)
A: Switch the unit OFF and unplug it. Empty the water in the base. Rinse the base with hot/clean water. Do not submerge the base! Visually inspect the base for dirt or mineral build up. If soft water is used decalcifying the unit every 4 weeks with EZ Cal is suggested. If hard water is used the unit should be decalcified every 2 weeks. Do not forget to reset the clean light after resetting the unit.

Q: Reset cleaning light (AOS U650, AOS 7135, AOS 7142, AOS 7144, AOS 7147)
A: The cleaning light does not automatically reset. Hold down the power button (button A in instruction manual) until the light stops flashing. The light automatically comes on approximately 14 days after plugging in the unit.

How to wire the humidistat to the transformer

your transformer should have multiple wires on it. 2 of them are for 120 volt side hook up usually black is your hot 120 v wire and white is the common or neutral wire. on the other side of the transformer you have 2 more wires these are your low 24v side colors can range from red,green, blue, yellow ect. the wires for 24v dont matter about polarity or which one you hook up. one is 24v and the other is common.

Dose the Goodman GPD075-3 have a fan oni have a red and white wire going to the thermastat, and a green one in the unit not hook up

depends on your stat, red goes to R on stat white goes to W on stat and if your stat has a G terminal that is so you enable the fan only without heat if not then this option won't be available to you.

Hi. It keeps going from the green light to the red light so its not generating any moisture. It does this on its own sometimes it runs for a while and sometimes it does it right away. Any idea what is...

This is usually a problem with the water float. Clean the float and assembly (see the instruction manaul) and that should fix it. The light is coming on cause the unit 'thinks' there is no water.

The unit works for a few minutes (green light) and then stops - is typical of a float that sticks when it gets to the bottom. So pay attention to that part of the assembly or the bottom of the float having grime or buildup.

Air-O-Swiss 7133

Okay, I just started getting this same deal with my 7133 on it's third season. I found in a blog that if you hold down the button that controls the heat while turning the mist knob on, it resets the machine. It worked. The red light went green and I turned off the heat button for cool air and the upper light still stayed green. Fingers crossed this continues to work. good luck!
