Every issue ranked. Every fix explained.

OnPoint ranks issues by dollar impact, severity, and ease of repair, then shows the evidence, the likely root cause, and how to resolve it.

Do this first

Restore the heating/cooling lockout on RTU-2

  1. Check the heating valve. Confirm commanded and actual position while the unit is cooling.
  2. Restore the lockout. Re-establish the deadband between heating and cooling setpoints.
  3. Mark it resolved. OnPoint keeps watching the same points.

The problem

Stop chasing symptoms. Know what to fix first.

Complaints and alarms catch some problems and miss others that quietly cost money. Digging through trend data by hand takes time your team doesn't have. Unresolved HVAC issues drain your budget and your team's time.
