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).
