Adjustable offset feature?

Sunday, December 11, 2011 by Aprilaire Team
Consumer question:

There is an offset between the actual room temperature and what the thermostat is reading. Is there a calibration setting or some adjustment I can make to alleviate this offset?


Aprilaires' response:

Thank you for contacting us with regards to your model 8353 Thermostat. This model does not have an adjustable offset feature. The thermostat should be displaying whatever temperature it's sensing.

Light a blinking, what does it mean?

Friday, December 9, 2011 by Aprilaire Team
Consumer question:

Just installed a 5000. When thermostat is in the off position and I set unit to run 30 min/hr., the blue lights on the cleaner flash and the filter indicator bars are animated on the LED control panel.

When on I place the thermostat on heat, and the heat kicks in, the blue lights on the cleaner unit do not flash but the filter indicator on display/control module is animated. Should the blue lights on the filter be flashing?


Aprilaires' response:

Thank you for contacting us. The unit is going to light up when it send a signal to the furnace fan to kick on. The 30 min/hour button will give you 30 minutes run time for the based on the total amount of run time in that hour. The run time of the heat call does count toward that 30 minutes and if toward the end of that hour the control has not reached 30 minutes it will kick on the fan to get the remaining minutes. The blue light should flash when ever the furnace does kick on and furnace fan runs. If you have any other questions please contact us at 800-334-6011. Thank you

Supply or return, where should my humidifier be located?

Friday, December 2, 2011 by Aprilaire Team
Consumer question:

The furnace is a high efficiency heat pump. The humidifier is installed on the supply plenum with the bypass running to the supply plenun. Is this optimal for energy conservation or would the reverse be better? This is for the Aprilaire Humidifier model 440.

Aprilaires' response:

Thank you for contacting us regarding your humidifer. The unit can function equally well on both the supply and return side. The air flow will always be going from the supply to the return and will provide for excellent evaporation.

Does my one touch control work?

Thursday, November 24, 2011 by Aprilaire Team
Consumer question:

The control for the air cleaner is saying it is filtering even when it is disconnected from the unit and also when the unit is not actually filtering.

Aprilaires' response:

Thank you for contacting us with regards to your model 5000 Electronic Air Cleaner. The air cleaner control works on a negative signal logic, meaning that when it sees no connection to the furnace or thermostat, it assumes the fan is running and the air cleaner is working. The control needs to be wired in properly in order to truly see when the fan is active or not. If it still shows Filtering when the control is connected, there may be a problem with the wiring. We would recommend that you contact your installer to troubleshoot the installation further.

Does my Aprilaire model 8365 thermostat have progressive recovery?

Wednesday, November 23, 2011 by Aprilaire Team
Consumer question:

Does this model have progressive recovery? Is that the proper term for coming on before the time set on the thermostat so that the system reaches the temperature by the time the program specifies without using emergency heat?


Aprilaires' response:

Thank you for contacting us with regards to your model 8365 Thermostat. This model does not have the Progressive Recovery feature. And you are correct in your definition of the term. Without that feature, this means that the thermostat will adjust its set points based on the schedule that has been preset. If the new temperature is higher than the previous set point by enough degrees, the thermostat may call for the auxiliary heat to engage. Aprilaire thermostats with this feature that are similar to yours are the 8465, 8570 and 8600. With this feature, the thermostat will anticipate the next setting and activate the heating or cooling equipment early to reach the next set point at the scheduled time.
Please let us know if we can be of further assistance.

Couple of questions on the model 600 Aprilaire humidifier...

Saturday, November 19, 2011 by Aprilaire Team
Consumer question:

I purchased the 600(digital) and have 2 questions... 1. Does the manual mode resistor come with this unit in case I cant install the temp sensor outside and 2. Will extending the temp sensor wires with like gauge wiring cause any issues? I have a 20 foot run to get outside and the temp sensor wires are a foot long! Thank you and any tips would be appreciated.

Aprilaires' response:

Thank you for your email regarding your interest in our model 600 Aprilaire humidifier. The model 600 humidifier control includes a humidistat which has an on board manual mode resistor. If you decide to use the outdoor sensor you will need to move the manual/auto switch on the humidifier control from manual to auto. This allows the control to use the outdoor sensor instead of the onboard manual resistor. You can extend the outdoor sensor using thermostat wire which is typically 18 gauge. The maximum length you can extend it is 300 feet.

How do I turn off the "Progressive Recovery", and have the heating start at a programmed set time.

Friday, November 11, 2011 by Aprilaire Team
Consumer question:

Is there a way to turn off the "Progressive Recovery", and have the heating start at a programmed set time.

While the idea is great, the furnace starting up wakes us, and we do not want it to turn on before our alarms in the morning. We are fine with it not getting up to temperature right away. We would prefer to set the time it comes on and off.


Aprilaires' response:

Thank you for your inquiry about the Aprilaire thermostat model 8463.

The model 8463 "progressive recovery" function can be disabled by the following steps:
1. Press "mode" until the unit is "off".
2. Press and hold the "up arrow" and the "mode" buttons together for three seconds, the screen will change.
3. Press the "mode" button until the menu item "15", progressive recovery, appears.
4. Press the "down arrow" button to change from "1" to "0".
5. Press the "mode" button until the word "done" appears, and press "mode" one more time.

This will set the thermostat to start the heating/cooling at the time specified in your schedule.

Thank you for the opportunity to help in this matter.

Is the Aprilaire model 8466 thermostat Dual Fuel capatable, if so how do you set it up ?

Friday, November 11, 2011 by Aprilaire Team
Consumer question:

Is the 8466 Dual Fuel capatable, if so how do you set it up ?


Aprilaires' response:

Thank you for contacting us with regards to your model 8466 Thermostats. There are two requirements for dual fuel mode. The thermostat must be in heat pump mode (set by the switch on the back), and the auxiliary heat must be set to Gas or Oil. Under these conditions, whenever the thermostat stages from compressor to auxiliary, the thermostat will lock out the compressor.

This thermostat can also act as a fossil fuel kit. When the outdoor temperature sensor is installed and enabled, the thermostat enables settings for high and low balance points. The high balance point will lock out the auxiliary heat when the outdoor temperature rises above that level. The low balance point locks out the compressor when the outdoor temperature falls below that level. In-between, the thermostat will stage based on demand. Please see your installation instructions for more information.

I have no return duct, which controller can I use for my new Aprilaire humidifier?

Monday, November 7, 2011 by Aprilaire Team
Consumer question:

I just purchased a model 600 with the automatic humidity control. I do not have a return duct. I was planning on running a 6\" duct from the unit to the inside of the filter box to make the unit work. I noticed the model 60 controller says it needs to be mounted on the return duct. Why can this not be mounted on the wall near my thermostat. I would think if I used stand-offs to allow air to get to the sensor this would work the same. Does the sensor need active air flow to work or would it still register the humidity if mounted on the wall? I would rather use the automatic function rather than the manual mode for obvious reasons.

Aprilaires' Response:

Thank you for your email regarding your model 600A Aprilaire humidifier. The model 60 humidifier control requires air movement to ensure the humidity sensor on the back of the humidifier control gets an accurate reading of the humidity. When mounted to a wall it is difficult for air to get behind the humidistat. Our recommendation would be to install the manual humidistat our model 4655.

What Thermostats work well with the humidifiers?

Monday, October 24, 2011 by Aprilaire Team
Consumer question:

What Thermostats work well with the humidifiers?


Aprilaires' response:

Thank you for your email regarding your model 600A Aprilaire humidifier. Some thermostats can control humidifiers if they have humidifier terminals. Aprilaire does not manufacture a thermostat which can control a humidifier. We ask for you to check with local heating contractors in your area for the thermostat they would recommend to use. As long as the thermostat has humidifier terminals that have dry contacts it can operate your model 600A.

Did I get the right Aprilaire Dehumidifier for my house?

Thursday, September 29, 2011 by Aprilaire Team
Consumer question:

I very recently bought the 1710A dehumidifier. I\'m concerned that it was the wrong product for my house though. I would like to discuss with someone whether the 1710A is a good solution for a finished basement (i.e. can it work through the walls to individual rooms in the basement) or if a whole house/central air solution would be more appropriate (and if so, general costs). The purchase is still recent enough that I should be able to return the 1710A model.

Aprilaire's response:

Thank you for contacting us about your 1710A dehumidifier.The 1710A is a great portable unit for use in spaces that are open and have good air flow from room to room. If your space is sectioned off into separate rooms that can be closed off from each other than the 1710A will not work as effectively as you might like.

In these situations we recommend going with a whole-home unit such as the 1750A. The 1750A would connect to your duct work and dehumidify the home equally. This may be your better option. The 1750A should cost about the same as the 1710A but there would be a charge for a dealer to install it. I would recommend contacting a dealer about installation prices.

Please contact us at 1-800-334-6011 for any further questions.

My Aprilaire Model 8570 thermostat is no longer displaying the outdoor temp, any ideas?

Monday, September 19, 2011 by Aprilaire Team
Consumer question:

I recently noticed that the outside temperature no longer displays on my Aprilaire 8570 thermostat. I have the outside monitor installed. It used to display. I just thought of this, but could it be that it is covered up by mulch or something which is preventing it from registering. If tha is not the case, could there be another reason? I am sure in the winter, snow could have the same affect unless it was placed some where that will not get covered by snow. Please let me know your thoughts. Thanks!


Aprilaires' response:

Thank you for contacting us with regards to your model 8570 Thermostat. The outdoor temperature sensor would not necessarily fail if it were covered, but only if the wires were cut or disconnected. In order to register the correct temperature, it should be placed outside, on a non-south facing of the home, away from any exhaust vents and above any potential snow line. Failure to do so could result in an incorrect temperature reading. If your thermostat has lost connection to the temperature sensor entirely, the failure could be with the sensor, the wire or the thermostat. Try removing the faceplate of the thermostat, give it 10-15 seconds to power down and then plug it back in. If the outdoor temperature comes back, it may have simply lost connection at some point. If it does not come back, you may need to have your installer or another HVAC contractor test the sensor. It should be tested at the wires inside the thermostat as well as at its installation position outside. If the sensor has failed, it should be replaced with part #8052. If the wire has failed, it might be possible to repair the wire, or else it should be replaced.
Please let us know if you have any further questions.

Aprilaire model 8466 thermostat questions

Monday, September 19, 2011 by Aprilaire Team
Consumer question:

Does my Aprilaire model 8466 thermostat have an auto mode. A mode where it will switch between cooling and heating automatically when the temperature drops at night?


Aprilaires' response:

Thank you for contacting Aprilaire regarding your model 8466 thermostat.

Your thermostat is capable of utilizing the "AUTO" mode. The HVAC contractor should have set up you thermostat to allow access to this feature. In order to check; all you have to do is press the mode button to switch between "HEAT", "COOL", "AUTO", and "OFF". If "AUTO" does not appear in the mode section, you will need to contact you heating/cooling contractor to correct this.

If you have other question regarding you thermostat please feel free to contact us.

How do I program my Aprilaire Model 8465?

Friday, September 2, 2011 by Aprilaire Team
Consumer question: 

How do I select 5/1/1 programming mode on my Aprilaire Model 8465? Documentation only explain how to program for 5/2.

Aprilaires' response:

Thank you for calling us regarding your Aprilaire Model 8465 Thermostat. To change the program mode, you need to access the advanced set-up options. Option 19 will allow you to adjust the program between 5/2 and 5/1/1.
