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.

II purchased the Aprilaire 400A humidifier with the model 60 control to replace an old foam type mounted on my 30 year old Temp-O-Matic FHA furnace. I have a pluming heating contractor wired it with a RIB relay to start the blower when humidity is called for. Not sure it's working correctly. When you turn the knob on the model 60 controller it doesn't come on right away. After awhile I go back and check and it is working. Is this normal?
