i think you are working on a cgaf chiller(air cooled cold generator) and this might be the problem that you are encountering
ok, if that is the problem you need to make adjustments on the following menu (system programing setpoints menu) and scroll down to the following setpoints and make the correct adjustments. ok, i hope this help.

GT1980, every IntelliPak chiller I have started, or even seen, has been set up as Gbrlgms suggests. That is, to limit chiller loading to 50% while the Hot Start STPT is exceeded. Even limited to 50%, the temperature will come down to below that setting, at which time the chiller will fully load. It sounds as though yours has been set up to lock out during this time. I suggest that you verify that the load(s) on the chilled water can tolerate the 80 degree (or higher) water ( I expect that would not be an issue - if so, what would the alternative action be?), and set this one up to limit to 50% also. When set up this way, there will be "Informational Warning" generated when this situation occurs, but there will be no trip and no manual reset required.

found in manual too the pages required for the programming/ too, the time interval of stretching restart (on one compressor it described) time frame to re-test it self as well.
Another man from Cleve Ohio Sals' Heating with there and another prev co said you folks REEEALLY HELPED ALOT ! and immediately asked if we were (I am attempting) communicating.
He tried the 'other h forum' and said he was pleased HVAC-TALK wants more "just stick to the thread" conversation with out all the HSCHOOL antics every time there's confusion.
-working on my HVeeze.
SYSTEM operational ! Thank you all.

it sat in the 94 deg day with another 'tech' (I dunno who I was that moment) checking a pump and left off for 30 sec , enough to trip pump flow proving sensor....
then the short time limit reset-test-itself mode was too short to restart.
Step-logic programming, like a ti-56 1976-used calculator in college, is clear enough in the manuals now. Reviewed until I have some grasp.
