Keypad Lockout

The Keypad Lockout feature allows the operator to lock the keypad to prevent tampering. If the Keypad Lockout feature is turned on, all keys except the ON Key and OFF Key are prevented from functioning. The unit can still be turned On and Off, but doing so does not clear Keypad Lockout.

To turn Keypad Lockout on, simultaneously press and hold the ON Key, CYCLE SENTRY Key, and HIGH SPEED LOCK-OUT Key for five seconds. The display shown ( ON Key, CYCLE SENTRY Key, and HIGH SPEED LOCK-OUT Key) will appear, with [0 - - - n] replacing the box temperature. When the three keys are released, the display will return to the Standard Display of box temperature and setpoint.

When Keypad Lockout is turned on, only the ON and OFF Keys are functional. All other keys are locked out. Pressing any key other than the ON Key and OFF Key will cause the box temperature to display [0 - - - n]. When the key is released, the display will return to the Standard Display of box temperature and setpoint.

To turn Keypad Lockout off, simultaneously press and hold the ON Key, CYCLE SENTRY Key, and HIGH SPEED LOCK-OUT Key for five seconds. The display shown ( ON Key, CYCLE SENTRY Key, and HIGH SPEED LOCK-OUT Key) will appear, with [0 - - - n] replacing the box temperature. When the three keys are released, the display will return to the Standard Display of box temperature and setpoint. All keys will function normally.
