Sta Rite heater SR400HD runs continuously and does not cut off

Recently, the heater runs continuously when the filter pump is running and does not cut off. Is this normal? I tried pressing all of the buttons on the membrane pad and there is no response. I believe the California sun has damaged the display...possibly the pad too.

The only light that is lit on the pad is Spa Only. Please help...thank you.
