Honeywell HE220A1019 Whole House Humidifier Humidifier - Page 3 - Answered Questions & Fixed issues

have you checked the damper ? is the motor running the right direction ? have you increased the water supply to it ? you need to be sure that it is coming on only when you have a call for heat, normally your humidistat should be installed near the return, or on the return duct, for proper sensing, you could try holding a pan of steaming water, placing the stat above it, not to close, to see if the stat shuts off the hum, a little trick, that way you will know if the stat works ok, hope these helped, thanks for the question, mr.grzz

Thanks for your question,
Well thats the big problem with bypass Humidifiers, they use alot of water, is yours running all the time, even when the furnace is shut down ? if it is, its wired in wrong, if not then there is not much of a solution for ya, is the humidity level in the home comfortable to where you can actually turn the house t-stat down ? if not you may want to incress the amount of humidity to be able to turn your house t-stat down, you should be feeling about 3 to 7 degrees warmer with the right amount of humidity, sorry I couldnt be more help, but thats the nature of that unit, just a little FYI, if you ever decide to try something different, may cost a bit more, try a steam humidifier, alot less water usage, its filtered, and pretty reliable too, thanks again for your question, hope atleast part of this helped !

Thanks for your question Mike,
The wiring for your humidistat and solenoid are fairly simple, you will need 24volt t-stat wire, you have the two wires at the Solenoid, one wire goes to the terminal board at the furnace, it connects to the (c) or common terminal, the other wire connects to one leg of the humidistat, run another wire from the other leg of the humidistat, to either the HUM terminal on your furnace circuit board, make sure its not a 120v leg, should say in the owners manual, if if is or your not sure, connect that same leg to the (w) terminal at the furnace, this way it only comes on in heating mode, some models need a second 120v-24v transformer, but you would still wire it through the same way, only exception is that you have to hook up 120v to the transformer, and route your wiring like I told you above but through the transformer to complete the circuit, hope that helped you out Mike, please let us know, thanks again, mr.grzz

thanks for your question,
you have to install the bypass humidifier on the supply side of your heating system, (hot side) and run a bypass pipe from the return side, (cold side), it does matter which side it goes on, you do not want water vapor going directly into your furnace, as this can damage it and shorten the life of it, your humidistat is installed on the return side of your duct work, this will allow proper operation of the unit as the humidistat senses the moisture in the air and brings on and shuts down the humidifier as needed. hope that helped to answer your question, please let us know what you think, again thanks, mr.grzz

Sounds like you Connected the humid trans fromer directly to a main power source. It should be either on the EAC or HUM term on the board of the furnace.

Check for 24volts at the valve. Some techs install these so it only comes on when the furnace calls for heat. It should have its own transformer.

Replace the Valve on the unit. Check the small filter inside of it where the waterline attaches first. If its clear and you have lots of flow from the 1/4" line the replace the valve.

Try the following test, ( I will resume this is a flow through humidifier)

Spray water directly oin the filter make sure it is saturated. Some water should leak from the bottom. After 10 min measure the Humidity to see if this helped. If there is a higher level of humidity the pbm is that not enough water is saturating the filter. Check the level of the filter & water feed nozzle.

Option 2 is to connect the water feed tube to a Hot water source.

Hope this helps.

Depending on the age, transformers do go bad. It will have a odor to it if it is burned out, I just checked and the doorbell transformer at home depot is sufficient to run the humidifer. Dont worry that it is 20VA instead of 10VA. The VA is just the load it can handle, the higher the number, the higher the load. The transformer at home depot is around $15 dollars. You will use the 2 outer of the 3 screw terminals for the low voltage. I hope the helps. Steve

No there is no polarity issue, either wire to either one it doesnt matter. Steve

The screw does turn and will open the valve, take the hex nut off and turn the screw to see if water leaks between the valve portion and the hexnut housing. They used that same valve on many models, including the newer models. Make sure you are getting water to the valve.

Sounds like the air flow is too great and it is blowing the water in the bottom of the tray around before it gets a chance to drain. Try placing your summer, winter damper at half closed to slow the airflow down a little.

I am having the same problem. I have had my humidifier for about 5 years now and I just started having the problem where the water continuously flows through the solenoid. I took apart the solenoid by removing the fittings from both sides. When I did that, I noticed that there was a hole in the metal that allowed me to see through to the other side. Apparently, it had corroded and and broken through, allowing the water to pass through the solenoid without really going through the valve within the solenoid. There are several sites that sell replacements for about $70, which is not cheap, but cheaper than buing a new humidifier for $120. Here is one site I found: http://www.iaqsource.com/product.php/honeywell/32001639-002/?product=112783&category=1142

trying to find wiring instructions for honeywell he220a1019 whole house humidifier.

You can try installing the water line to your hot water if it is installed on cold line for more humidification. You should make sure your humidistat is up line 6" @least from humidifier for proper humidification measurement.

Mine had the same problem no water through the solenoid. It turned out to be the little adapter with the needle hole on it, attached to the solenoid on the intake side. It was clogged, cleaned it out and works great now.

solonoid valve not shutting off on water line .

Question edited for clarity, hemostat to humidistat. A hemostat (also called a hemostatic clamp, arterial forceps, or pean after Jules-?mile P?an) is a surgical tool used in many surgical procedures to control bleeding. (Hemo - Blood) For that you will need dealer service. The only thing you can try is a Power Reset. Turn off the power to it by removing the power lead for at least two hours to reset the control board. https://www.google.com/search?q=Honeywell+Trueease+HE+250a-1005+short+cycling ..

It sounds like the wiring for the humidifier may not be correct. The solenoid valve, which controls the flow of water to the humidifier, should be wired to the humidistat and the transformer, not to the furnace or fan. It is possible that the bottom wire of the solenoid is connected to the wrong terminal on the transformer or humidistat, or that the top wire is connected to the wrong terminal on the humidistat. I recommend consulting the installation instructions for your specific humidifier model, or consulting a professional HVAC technician to verify the correct wiring.

The drive belt is broken then and it needs to be replaced.
