How to program an Aprilaire 8463 Thermostat.

Consumer question:

My 8463 Aprilaire Thermostat was installed with a new furnace and A.C. The thermostat was programmed to 5-2 by the installer. I want it to 5-1-1. The installer did not know how to do it and the companies techs are stumped. How can I change this thermostat from a 5-2 to a 5-1-1? Or can I? I would like the settings for Saturday and Sunday to be different.

    The battery indicator on my 3 Y.O Aprilaire 8463 showed low battery so I replaced them. When I did the display read ‘OFF’. I pressed the ‘MODE’ and ‘UP’ buttons together and held them for 3 – 5 seconds and ‘OFF’ remains on the screen. I even held in the ‘RESET’ button and tried again. No luck. Any ideas?
