FAQ — dual interval PMS
Which due date takes priority?
When both calendar and running-hour intervals apply, Actinium-sm (and good PMS practice) uses the earlier due — “earlier condition wins”.
Can I extend a maker interval?
Only with condition evidence, company change control, and Class approval where the item sits under survey/CMS.
What if daily average RH is unknown?
Use a conservative estimate (e.g. 16–18 hrs for continuous operation) and refine from noon reports.
