Unplug the unit and see what happens. The face controls zone 6 (main zone) only. Change the dip swtch settings to another zone and see what happens. You can also swap out keypads, if you do that write down what the dip switch settings are so you can pit it back how it was.
Power off the unit when you make changes.
