Have had a Aprilaire model 560 humidifier since 1995 but looking for a new one, please help!

Wednesday, February 20, 2013 by Aprilaire Team
Consumer question:
 
Could you please find us the square footage the model 560 aprilaire humidifier unit is rated for? I'm exhausted trying to find any 560 information, we have had this one since 1995. We're considering one of your larger, more modern units. Thank you.
 
Aprilaires' response:

Dear Rich,

Thank you for your email regarding your model 560 Aprilaire humidifier. The model 560 was discontinued in 2002 and replaced by the model 600. Both models will effectively humidity a tight home up to 4000 square feet with a .50 air change rate. As homes age they can become less tight and humidity can escape. We design all our Aprilaire humidifiers to maintain an indoor humidity level of 35% at an indoor room temperature of 70F anytime the outdoor temperature is 20F or above. The operating time of the HVAC system will directly affect the operating time of your model 560.
 

 

Can I run and Aprilaire 600 in manual mode?

Tuesday, February 19, 2013 by Aprilaire Team
Consumer question:
 
I WAS WONDERING HOW TO RUN THIS UNIT IN A MANUAL MODE. I SEE HE LEFT A DOUBLE PRONG THING TAPED TO THE FURNACE THAT SAYS MANUAL ON IT BUT I DONT KNOW WHERE IT GOES. THANKS FOR THE HELP
 
 
Aprilaires' response:

Dear Randy,

Thank you for your email regarding your model 600 Aprilaire humidifier. Your model 600 can be set up as an automatic or manual control. In automatic there is an outdoor sensor connected to the control which will allow the control to automatically adjust the humidity level as the outdoor temperature changes. In manual mode you will need to adjust the humidifier control as the outdoor temperature changes. If not, you may over humidify your home. If you choose to run in manual mode simply remove the outdoor sensor from the terminals labeled odt and connect the manul model sensor instead.


Thank you for giving us the opportunity to be of service

 

I'm trying to decide between the 400, 600 and 700 Aprilaire whole house humidifiers? Please advise.

Hello Dan,

Thank you for contacting Aprilaire.

Yes, the 400 does not drain, it will evaporate all of the water used.

The 600 uses no power, so would be less expensive to run than the 700.

When the 700 is operating, it is drawing air from the duct work, humidifies it, and blows it back into the duct work all in one spot. Also, yes, sometimes it has been reported that cold air would come out of the vents in the 700 during usage of the air conditioner.

It is difficult to offer 'utility expenses' since each home uses different amounts of water or electricity depending on the humidification needs.

Please let us know if you have any further questions.

Comments: I\'m trying to decide between the 400, 600 and 700 whole house humidifiers. I like that the 400 wastes no water and uses cold water. Does the fan in the 700 draw air in from the basement or is it sealed so it only pulls heated air from the duct? Would air conditioned air escape from the 700 into the basement during the summer?About how much energy does the fan use on the 700? Will this cost me like $20 more per year in electricity than the 600, for example? How much less would the 400 be in utility costs than the 600 or 700? Thank you!

When should my Aprilaire model 700 humidifier run?

Thursday, January 3, 2013 by Aprilaire Team
Consumer question:
 
Since my model 700 was installed last winter, I've noticed it sometimes runs even if the heater isn't running. Also, sometimes, if the heater is running, the humidifier does not. It seems to run completely independently of whether the heater is running or not. Is this normal?
 
Aprilaires' response:
 
Thank you for contacting us. The humidifier does not regularly run independent of the furnace when wired to turn on and off with the furnace heat call. If you turned the humidistat down when the humidifier was running, does the humidifier turn off? If the humidifier stays on when the humidistat is turned down, then you would have a bad solenoid. If the humidifier turns off then you have a good humidistat and good solenoid.

Do you have a digital humidistat that you are controlling the humidifier with? The digital humidistat has a blower activation switch on it and you might have that in the on position. Turning the blower activation switch to the off position should solve your problem of the humidifier running in these different times.

If you have a manual control to wired to the humidifier, then you would need to have your service contractor trouble shoot the current sensing relay that would be wired between the humidistat and humidifier.
 
If you have any other questions please contact us at 800-334-6011. Thank you

 

Does basement humidity have affect on my humidifiers operation?

Monday, December 31, 2012 by Aprilaire Team
Consumer question:
 
Aprilaire model 500 humidifier installed on 2-stage 95% furnace. Sensor is located inside cold air return from house. Cold water to humidifier. Does basement humidity have affect on humidifier operation ie. humuduty levels in residence. Have dehumidifier in basement set at 40%. On setting five humidity in residence is 32-35% Setting 6 36-39% Is this normal? I think it should be higher. Humidifier works in test mode. Insight?
 
Aprilaires' response:

Thank you for your email regarding your model 500 Aprilaire humidifier. Your Aprilaire humidifier control measures the humidity in the cold air return which is the air coming back to your HVAC system from your entire home. A dial setting of 5 would be equivalent to an indoor relative humidity of 35% anytime the outdoor temperature is 20F or above and the indoor temperature is 70F. A dial setting of 6 would be equivalent to an indoor relative humidity of 40% anytime the outdoor temperature is 20F or above and the indoor temperature is 70F. We design our humidifiers to maintain 35% anytime the outdoor temperature is 20F or above and the indoor temperature is 70F. The actually humidity a specific home will vary due to the tightness and cubic footage of the home as well as the runtime of your HVAC system. In addition a humidity level higher than 35% may cause damage to home. This is because as the temperature outside drops, the air in your home may not be able to maintain a humidity level above or even equal to 35%. If the humidity level is too high for the current outdoor conditions, the result is condensation on your windows. This is described in the attached owners manual. Based on the information you provided it appears your mode 500 is performing properly.

 

New model 400, installed 8 days ago...but I'm still a little dry?

Monday, December 3, 2012 by Aprilaire Team
Consumer question:
 
I had an Aprilaire 400a humidifier installed on my 3 story town home (1 1/2 years old) about 8 days ago. After adjusting settings on the unit, the humidity in my home peaks at approximately 27% at maximum settings and with the blower on.

This morning was the highest that the unit registered and that was 37% internal humidity, but it rained all night and the humidity outdoors was above 50%.

I have contacted the dealer/installer and they assured me that they're going to talk to their management to see if there's an issue, however I am told that it may just be because of my home.

I'm not sure if that's accurate, as my home is less than 2 years old and is tightly constructed. I went with the larger humidifier that they offered, however i'm concerned that reaching 27% humidity on max settings when it is 25-35 degrees outside is going to be an issue.

Any feedback you can provide would be greatly appreciated.
 
 
Aprilaire's response:

Thank you for your email regarding your model 400 Aprilaire humidifier. Any Aprilaire humidifier is reliant on the HVAC system to be operating in order to add humidity to your home. While your model 400 will add some humidity during a blower only call, it primarily is adding humidity during a heat call. If your heat call is short, then the humidifier will have a short operating time as well. Homes also will require time to build up the humidity level when a humidifier is first installed. Since your model 400 was only installed 8 days ago it may just take more time to raise the humidity level. At this point we would ask you to give it another week or two. Your home has had all winter to lose moisture and it will take time for the home to soak up moisture created by the humidifier.

 
 

 

Should my Aprilaire humidifier run ONLY when my furnace is running?

Monday, October 29, 2012 by Aprilaire Team
Consumer question:
 
I have an Aprilaire model 700 and I assume it's normal to turn on my heater's blower in automatic mode to raise humidity? When I turn it down from 5 to 3, the blower doesn't turn off. Is that normal?
 
 
Aprilaires' response:
 
Thank you for contacting us regarding your model 700 humidifier. When installed and wired properly, the humidifier should only turn on after the blower has been activated due to a heat call or fan call from the thermostat. If your control has the optional blower activation function, it may extend the blower and humidifier run time after the heat call has been satisfied. However, if you are using the blower run extension, it should turn the blower off if you lower the humidity level. We may need more information to fully understand your particular situation.

Additionally, to better understand the functionality of your unit, you have the option to call our technical support department at 1-800-334-6011 to discuss it with one of our technicians over the phone.

If you have any further questions regarding this or any of our products, please feel free to contact our customer service department at your earliest convenience.

Faulty wire connection?

Wednesday, October 17, 2012 by Aprilaire Team

Consumer question:

Hi: I have the 8570 thermostat pn 61000229 rev c with a 700a humidifier; ADHC model 58; 61000501 rev b.
The adhc is wired to the 8570 for activation. The supplied outside sensor is also used. It works but intermittenly the 8570 screen goes blank while operating and causes the adhc "call dealer for service" light. the E4 code appears on the adhc. I had the heating tech out for annual service and could not find anything wrong. The only other symtom that I noticed was it occurs in the temp range freezing or above. During continous freezing weather, it did not seem to need to be reset as much.
I have rechecked the wiring between the 8570 and adhc and it is correct. The intermitten screen blank on the 8570 makes me believe that either the unit is faulty or an intermitten power loss.  Any thoughts?

 

Aprilaires' response:

Thank you for including Aprilaire as part of your home comfort system.

The description you have given us sounds as though there is a problem with the communication between the 8570 thermostat and the model 58 humidistat. You may want to recheck that all the connections at the ADHC and 8570 are snug, including the sensor to the outdoors. If the connections are snug and the fault reoccurs, you may remove the "A" and "B" wires between them and determine if the fault reappears. If it does not then the problem would probably be a broken wire.

If you have further questions, or need more assistance, feel free to contact us.

 

How do I get more humidity out of my humidifier?

Friday, August 24, 2012 by Aprilaire Team
Consumer question:
 
Just installed a 600 unit. We had to turn blower on because furnace time alone was not increaing the RH enough. Will the blower shut off once the desired RH is reached or do I need to flip the switch? My concern is that without the blower the desired RH might not be attained.
 
Aprilaires' response:
 
Thank you for contacting us regarding your model 600 humidifier. If the control with your model 600 is the model 60 automatic digital humidistat control (ADHC), you have an optional blower activation built into the control. When wired properly, the model 60 can extend the blower run time to allow your humidifier to continue to run after a heat call has been satisfied. Once the humidity set point has been satisfied, the blower activation will turn off automatically.

If your control does not offer the blower activation or you are not using the available blower activation, the control does not have the capability to turn off the blower when the humidity set point has been reached. In this case the blower would need to be turned off manually.

Additionally you have the option to call our technical support department at 1-800-334-6011 to discuss this with one of our technicians over the phone. Our tech support department is available Monday through Friday, 7 am to 5 pm CST.

If you have any further questions regarding this or any of our products, please feel free to contact our customer service department at your earliest convenience. 1-800-334-6011.

 

Lots of water running down the drain tube, is that correct?

Thursday, June 28, 2012 by Aprilaire Team
Consumer question:
 
I had a model 700 Aprilaire humidifier installed yesterday and have a couple of questions;

1) it seems to have a lot of water when running coming out of the drain tube, is that normal?
2) I had to install the hunidifier on the return side becuase there was no room on the feed side of the furnace. I put the thermostat on the return side also but the reading goes way up and then back down when its operating when it kicks on and off. Should I put the thermostat on the feed side so its not on the same side as the humidifier? Its running in manual mode right now, I have to run the sensor outside adn my basemnet is finished so thats going to be a challenge.

 
Aprilaires' response:
 
Thank you for choosing the Aprilaire line of humidifiers for your home comfort system.
 
The amount of water that is discharged down your drain should be approximately 3 gallons per hour. Your description of the extreme humidity swings when the unit is cycling on and off lead me to the conclusion that the humidifier control may be mounted too close to the humidifier, or is mounted between the humidifier and the furnace, allowing for the humidifier output to affect the sensing of the control. It is recommended , in the installation guide that the control should be mounted at least 6" upwind of the humidifier.

If you have other questions regarding your Aprilaire 700 humidifier, please contact us at the number below. We appreciate your business.

Should my Aprilaire Humidifier be hooked up to hot or cold water?

Friday, June 8, 2012 by Aprilaire Team

Consumer question:

I have a Aprilaire 600m model and should I conect the water supply to the hot or cold line.

 

Aprilaires' response:

Thank you for your email regarding your model 600M Aprilaire humidifier. Your Aprilaire humidifier will operate on hot, cold hard or soft water. We do however recommend hot water as it will increase the evaporative capacity of the humidifier. Hot water will also allow you to operate your humidifier during a fan call. A heat source is required for the evaporation process. During a fan call the only source of heat is hot water.

 

 

My model 400 Aprilaire humidifier is not running in normal conditions, suggestions?

Wednesday, May 23, 2012 by Aprilaire Team
Consumer question:
 
Water flows and humidifier on light comes on only in reset mode but humidifier does not come on and activate water flow in normal mode. I have turned dial to max humidity but still does not activate water flow when furnace comes on. I am running in automatic mode with wiring installed per installation manual. I have the outdoor sensor installed but not run outside yet. Please advise. Thank you
 
Aprilaires' response:

Thank you for your email regarding your model 400 Aprilaire humidifier. If the outdoor sensor is in an area where the temperature is above 60F the humidifier will only run in the test mode. You may confirm this by moving the manual/auto switch to the manual position. This will allow the control to work off the manual sensor on the control rather than the outdoor sensor.
 

 

I have manual control for my whole house humidifier. I've been noticing water on the windows in the morning.

Saturday, May 12, 2012 by Aprilaire Team
Consumer question:
 
I have manual control for my whole house humidifier. I've been noticing water on the windows in the morning. When I look at the humidistat it is set for 32% (doesn't say RH but thats what I assume). I got another Aprilaire humistat that just measures RH and put it on top of my existing control. Where the existing control indicates about 32%(5% hysterisis) the standalone unit indicates 44%RH. How do I know which is correct and what do I do if my existing manual control is wrong? IS there a way to clean or calibrate it?
 

Aprilaires' response:

Thank you for your email regarding your Aprilaire humidistat. If you turn the dial from left to right you should hear two clicks. The actual humidity in your home will be the area between the two clicks. For example, if the humidistat clicks at 30% and 36% your actual humidity would be 33%. There is not a way to calibrate the humidistat. It is unclear from your email if the original humidistat is an Aprilaire humidistat, so it is difficult to say if it is out of spec. The accuracy of our Aprilaire manual humidistats are +/- 5%

The moisture on your windows is due to the surface temperature of your windows reaching dew point. This occurs when there is more humidity in the home than what the home can hold based on the current outdoor temperature. As the temperature outside drops you want less humidity in your home. For example when the outdoor temperature is 20F or above we recommend 35% humidity at a room temperature of 70F. If the outdoor temperature drops to 0F you'll want 25%.

Thank you for giving us the opportunity to be of service.

My Aprilaire model 760 humidifier that has worked great for the last 11 years has a short

Thursday, May 10, 2012 by Aprilaire Team

Consumer question:

My Aprilaire model 760 humidifier that has worked great for the last 11 years has a short that apparently cannot be repaired. So what would it cost to get a new one that will fit my furnace exactly like my 760 did. Also the cost of a new one, or can mine be sent in for repair.

 

Aprilaires' response:

Thank you for using Aprilaire products in your home comfort system.

I am sorry to hear that your model 760 has failed after 11 years of service. I am please to let you know that you local heating and air conditioning company can assist you in obtaining a replacement for your model 760. Our current model 700 humidifier would replace the model 760 for area coverage, the dimensional size may vary slightly.

 

No water comes in to the model 500 aprilaire humidifier when running. What could be happening?

Wednesday, May 9, 2012 by Aprilaire Team
Consumer question:
 
No water comes in to the model 500 aprilaire humidifier when running. Could it be a problem with the solenoid valve??


Aprilaires' response:

Thank you for contacting us.
No water could be an indication of an issue with the solenoid valve.
If you have an Automatic Control try putting it into test mode:

A. No click at the solenoid valve indicates an electrical problem. Contact the heating and air conditioning dealer to further check the electrical components of the Aprilaire Humidifier.

B. If the solenoid valve makes a click sound and there is no water draining from the unit, this would indicate the flow of water is being obstructed.

1. To determine if water flow is being obstructed, turn the dial of the humidifier control to the off position. The first location to check for an obstruction would be at the saddle valve located on the water line supplying water to the humidifier. When checking the saddle valve, make sure it is completely open. This can be done by turning the valve all the way to the left. If anything is clogged, it can be dislodged by turning the saddle valve all the way to the right and back to the left. Once this is done, turn the humidifier control dial above the click point and water should be coming out the drain line.

2. If water is still not coming out of the drain, check the orifice and in-line strainer to make sure they are not clogged. The orifice is located in the tube on the outlet side of the solenoid valve and the in-line strainer is located on the inlet side of the solenoid valve (see attached). The orifice may be cleared by inserting a needle through the small opening. The strainer may be cleaned by running it under warm water to dislodge deposits or replace it. After clearing and re-installing the orifice and strainer (be sure to double wrench all water connections), turn the humidifier control dial above the click point and water should be coming out the drain line.

 

What is the minimum water temperature to supply an Aprilaire 350 humidifier?

Tuesday, May 8, 2012 by Aprilaire Team
Consumer question:
 
What's the minimum water temperature needed to supply this Aprilaire model 350 humidifier unit? We want to reduce the water temp for the summer so it doesn't heat the house while it runs. Here in Denver we still need the moisture all year around.

By the way, do you make a in-the wall ultrasonic unit with a humidistat, that can run from filtered water that removes minerals and chlorine?
 
 
Aprilaires' response:

Thank you for your email regarding your model 350 Aprilaire humidifier. The minimum water temperature for our self contained humidifiers is 140F. This is required in order for the evaporation process to take place. When the hot water flows over the water panel, the water evaporates off the water panel and into the room temperature air moving through the water panel. Lowering the water temperature will reduce the amount of humidification produced. The water to the humidifier can be hard or softened but should not be from a reverse osmosis system. We do not manufacture ultrasonic humidifiers.

 

I need humidity in the Summer, what should I do?

Wednesday, April 25, 2012 by Aprilaire Team
Consumer question:
 
My heating/air cool unit is now controlled by a new thermostat that allows fan circulation about 35% of the time whether the heat or cooling is running or not. Will the humidifier work when the fan is on whether it is on heating or cooling? I live in an area which humidity averages about 12% during the summer. I need to add humidity during those times.
 
 
Aprilaires' response:

Thank you for that very good question regarding the Aprilaire humidifier operation.

The answer to your question depends on the type of humidity control that was installed with the humidifier. In the event that the humidity control was the type that used an outdoor temperature sensor to regulate the humidity, then the humidifier would not add humidity in the summer months. this type of control would disable the humidifier when the outdoor temperature would go above 60 degrees. If the humidity control does not use the outdoor temperature sensor, then you may be able to humidify during the summer months. Just be aware that the air conditioning system will remove some humidity during its normal operation; which would take longer to bring the humidity level up.

 

Summer time use of my Aprilaire Humidifier Model 700?

Tuesday, April 24, 2012 by Aprilaire Team
Consumer question:
 
I recently moved into home that has Aprilaire Automatic Humidifier Model number 700. My question is during the Summer time when I switch the heat off and turn on the A/C at the thermostat. Will the Humidifier stay off or do I need to somehow turn the unit off?
 
Aprilaire response:
 
Thank you for contacting Aprilaire.

To live in Indiana, the humidifier would typically not bother to come on during summer, as nature gives us more humidity than we need. Any time the level of humidity is higher than the selected level, (or max of 45%) the humidifier will not come on.

Some people, just to make sure, will go ahead and turn down the humidistat to 'off' or at least the lowest setting. Then, for the same reasons as listed above, the humidifier will not come on.

Please let us know if you have any further questions.


 
 

 

The Aprilaire 8463 thermostat has Auto, Off, Heat, Cool, and Em-Heat system modes

Monday, March 12, 2012 by Aprilaire Team
Consumer question:
 
The Aprilaire 8463 thermostat has Auto, Off, Heat, Cool, and Em-Heat system modes. How do you select Auto. On my thermostat it does not present me with the Auto option.

Can an in-line fan be added to my Aprilaire humidifier?

Wednesday, February 29, 2012 by Aprilaire Team
Consumer question:
 
Can I add an in-line fan to the humidifier bypass duct in order to increase the humidity?
 
Aprilaires' response:

Thank you for contacting us with regards to our model 400 Humidifier. This humidifier requires between 60-100 CFM to operate properly. If the air provided to the humidifier is lower than 60 CFM, an in-line fan may help increase the humidification rate, but it should only run with the furnace. As a drainless model, it does not humidify well without a source of heat to evaporate the water.
