Place limits on the program
setpoints or the local setpoints
when the controller is in program
operation.
* Places the limit on the program
setpoint, local setpoint, or
remote setpoint during program
operation.
* When LP2 lamp is on, SPH
and SPL limit the program
setpoint for program pattern 2
retransmission.
* This does not work when
a program pattern is being
created.
