Can I lock all the keys on the panel?

There are 2 keypad lock modes: the full lock, or the partial lock. The full lock, as the name implies, locks ALL keypad functions. The partial lock locks only the programming functions; the Pump, Blower, and Light keys remain useable.
To lock, press on the Pump 1 key for 5 seconds. At that point, “LocP” will be displayed. If the key is released at this time, keypad will be in partial lock. however, if the lock key is kept pressed for another 5 seconds, “LocF” will appear and the keypad will be fully locked.
Note that a power-up unlocks the keypad.
