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.

I have an Aprilaire 600, and had the A/C unit removed temporarily for basemant work. The HVAC tech also removed my ODT sensor and lost it. I purchased another and see 4 wires on the outside not 2. Two going to the humidistat and two to the curcuit board on the furnace, red -Y Y2 & white -C. I assume I connect the ODT to the humidistat wires, what about the other 2?

Thank you for your inquiry about the Aprilaire humidifier model 600.

Yes, connect the sensor to ODT terminals on the humidistat. The other wires at one point probably went to the outside condenser.
