Hi! My name is ***** ***** I can assist you with this. I may need some additional information from you first in order to give a complete answer.

T​hey seem to have a lot of issues with this model. Do you have the User's Manual for it? Sometimes disconnecting it for about 5 minutes will allow it to reset and if that isn't successful, a system reset can be done. Get back to me about the manual and we can go from there. All follow ups are included in our one time fee. No time limit.

I cannot find the manual

See the attached link for a copy of this. Try unplugging it for about 5 minutes and then plugging it back in again. See if that resolves this. If not, try a reset as per the manual and see if it corrects the problem. Let me know what happens.

Programming is in section 15.
