The computer setpoint override will continue until "SHED" from
communications occurs or the controller is placed into monitor mode
through communications. Doing periodic "SLAVE READS" within the
shed time will allow the override to continue until communication is
stopped and shed time elapses.
0 Shed (code 154) allows the override to continue indefinitely or until the override
is canceled. (See override selection ID code 183.)
When SP is overridden, the upper display will flash "CSP" (provided the
SP Programmer is not enabled) and the lower display will show
"CSXXXX."
