Aprilaire 8466 programmable thermostat is displaying LO for indoor temperature and auxiliary heat is running constantly. What do I do to get it back on scheduled mode and temperature settings?

Look first and see if thermostat has batteries.If so lets start by changing them.

Customer: replied 1 year ago.
Already changed the batteries. They are backup anyway. And the LO is a room temperature indicator. Please do not offer any other advice. I will pay for this one time if required but I DO NOT want a monthly charge. Your website was deceptive and entrapment.

I have someone qualified coming to service the system.
