Changing local setpoint
1, 2, or 3
Use the procedure in Table 5-11 to change any of the local setpoint
values.
After changing a local setpoint value, if no other key is pressed, a
minimum of 30 seconds time will elapse before the new value is stored in
nonvolatile memory. If power is removed before this time, the new
setpoint value is lost and the previous setpoint value is used at power up.
If after changing the LSP value another key is pressed, then the value is
stored immediately.
