My Aprilaire thermostat model 8346 unit shuts off, after I hit reset, a code of 11 displays

Aprilaires’ response:
Thank you for contacting us with regards to your model 8346 Thermostat. If the Reset button does not restore normal operation, and if you’ve tried replacing the batteries, something is likely wrong with the thermostat. It may have suffered a static shock that damaged the components on the circuit board. If the unit was installed in 2009, we would recommend that you contact your installer for a replacement model.

Please let us know if you have any further questions.

    Unit reaches set temp then shuts off. Cannot lower temp to get it to operate , it keeps going to off. After several ( 5-10 ) minutes of debating back and forth as to whether to call A/C man the unit starts to work. When problem began we replaced the batteries which seemed to help but after about 2 weeks it’s back again.

    The temperature screen went blank, and a friend told me to hit the reset button; but I could not locate it. Please help; or let me know what to do for the light to come back on; thank you.

    Please advise WHERE a reset button is located on my Aprilaire thermostat model 8346. I heard there supposedly is a "reset" button but cannot locate it or find it mentioned in the owner’s manual. If there is no "reset" button, can the thermostat be reset manually, and if so, how? Thank you for any information you can provide to me.

    I set the thermostat to "cool" with set temp about 10 degrees below current temp. HEAT comes on. Can this be a thermostat problem or would it be something else?
