Customer Question

How do I restart my 8444 Aprilaire thermostat? I turned the AC mode selection off for several days. Now when I press any buttons, There is no reading/message available. I have replaced the batteries and pushed the reset button. I am wanting to start the AC mode.
JA: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?
Customer: Something specific to the thermostat.
JA: Do you plan on doing the work yourself?
