960 Control Troubleshooting
Alarms
The Model 960 continuously monitors itself and sounds an alarm if it detects something wrong. The alarm is a beep that is on for one second and then off for nine seconds.
When the alarm sounds, the display shows the letters “Err” with a number from 1 to 4. The table below lists the Err numbers, a description of each error, the cause of the error, and the solutions. To silence the alarm, press any button on the control. If the error still exists, the control will go back to the alarm condition after 30 seconds.
