@desieranks sometimes the fire alarm, or high static pressure safety will be wired to DI4 but in this case those safeties are wired in series with the fan start/stop signal so a jumper is needed on DI4. The input numbers are programmable and can change, but that's the basic idea. A jumper will be put in place if the safeties are wired in somewhere else.
This video saved my life and my job 🙏🏼
Thank you
Keep these video coming.
I'm glad you are getting something good out of them!
What are those jumpers for
