Apex Program Help

I want to turn on a fan when the chiller is on and stay on for 10 more minutes when the chiller is off then turn off the fan. Would this set of code work?

Fallback OFF
If Outlet Chiller = ON Then ON
If Outlet Chiller = OFF Then ON
Defer 010:00 Then OFF

I think this is what you want.
question, if the chiller is controlled by the apex via temp., why not just control the fan via temp?

Good point. I am going to try controlling the fan with the same temp setting that cut off the chiller.

what's the fan for, to cool the sump water or for to move air for the chiller?

the fan is moving air around the chiller when it is running
