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 have an Aprilaire 600 series humidifier that I run in manual mode as an outside sensor was never installed. Water runs to the solenoid and all the lights to the humidistat appear normal. However, I do not ever hear the solenoid click and no water is passing through it to the black tubing into the unit. Thoughts on a solution - not wired correctly or bad solenoid ?

Thank you for your inquiry regarding your model 600 Aprilaire humidifier. The maximum humidity level our humidifier control can attempt to attain is 45%. If the humidity level on your humidifier control reads 45% or higher or if your HVAC system fan is not running, the humidifier will not operate. You may test the operation of your humidifier control by turning on the heat for your HVAC system and turning the humidifier control dial to the test mode. Provided everything is wired correctly the humidifier should operate for 1 minute in the test mode. If not you will want to have your HVAC installer review the installation.

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