I recently had a contractor install a furnace/AC in my home. He included
a Aprilaire humidifier with the package. It's a Aprilaire Model 600 Series Humidifier.
I have a few questions:
1. The humidifier control baffles me. I went through the owners manual
and it's not clear. Refer to the attached pic. You'll see that the Manual
Mode handle (resistor case) is pulled out from the humidifier control box.
Does tha3. t mean it's in Automatic mode ???? The owner's manual and
installation instructions don't even tell you. There is an Automatic Mode
(Figure A) pic in the owners manual, but it's not my humidifier control box
nor does it have this Manual Mode handle. But on the Manual Mode pic in
the owners manual (Figure B), it shows this manual mode handle, but it
appears to be pushed in toward the humidifier control box. The owners
manual never says anything about pushing this lever in, or pulling it out,
or anything like that. My question is how do I know this humidifier control
is on Automatic ?? Or can it never be on Automatic with this Manual Mode
handle installed ??
2. Are you supposed to put the bypass damper handle on "Summer" during
every summertime ?
3. Is 35% a normal setting for the humidifier control? I think that's
what the contractor said to keep it on.
I want the humidifier control to be on Automatic. I don't want it to be in
a Manual mode.
Can I register my humidifier (for warranty) even though it was purchased and
installed by a HVAC contractor ?
Aprilaires' response:
The model 600 humidifier can be installed to operate either manually or automatically. How the control is installed and wired will identify the current operation of the humidifier. Based upon the information provided in your email it appears that you application is currently wired to operate manually. The blue manual mode resistor that is currently seen at the humidistat identifies that the product is currently setup for manual operation. This basically would require that changes be made to the setting at the control anytime there is a noticeable change to the outdoor temperature. The other operating option that is available for the model 600 is automatic operation at the humidistat. When the humidistat is in automatic mode an outdoor temperature sensor would need to be installed and wired in place of the blue manual mode resistor. When the outdoor temperature sensor is being utilized this will allow complete automatic control of the humidifier. The outdoor temperature sensor will take approximately 400,000 temperature reading daily and adjust the setting throughout the day based upon the outdoor temperature. We do not recommend utilizing the blue manual mode resistor and the outdoor temperature sensor at the same time as this will cause operating issues with the product.
In regards to the bypass damper of the model 600 does require that the arm be positioned into the summer mode during that season. This will allow any airflow during the cooling season to be directed away from the bypass arm of the application. If the damper is not placed into the summer position it will not cause any harm but rather allow a small amount of air to bypass through the arm.
