Keypad Lockout.
This security feature allows you to lock out the keypad to prevent unauthorized tampering with the program. Two levels of security are available, Total
Keypad Lockout or Partial Keypad
Lockout. Total Keypad Lockout renders all buttons inoperative. Partial Keypad Lockout allows only the 
or 
to operate for temporary temperature overrides. It also limits the temperature to the maximum heating and minimum cooling temperatures used in your program. This is
especially useful in buildings where unscheduled events are common. Anyone can change the temperature, but only between the temperatures you set and only for four hours or the number of hours you specify if you set up your Hold Till timing (see Temporary Program Override, page 18). To select or deselect this feature, refer to the USER CONFIGURATION section (page 11, steps 1 and 2).
