Frequently asked questions

• I cannot find the PMOC menu. It is in Operations › PMOC and appears for whoever has Read on the Tickets row (Operations group) or on Maintenance plans (Planning group). To act — create, save, activate, generate — you need Create/Edit in Maintenance plans (chapter 1).
• Can I build the PMOC in the app? No. The PMOC is built on the web. What goes to the app is the preventive ticket, executed like any other (chapter 8).
• Do I need one PMOC per building? Yes: one PMOC per site, and only one active per site. If the company has several buildings, each one is a site with its own PMOC. If a site groups several buildings, the equipment of all of them enters the same inventory — separate them by rooms (chapter 5) or create one site per building.
• The equipment does not appear on the Equipment tab. Only assets of the HVAC family whose site is the PMOC site or a site below it enter. Check the family and the site on the asset page (chapter 2).
• The activity periodicity says 30 days, but the tickets come out every 90. The schedule follows the periodicity of the task template, not of the activity. The Periodicity column warns in amber when they differ: edit the template or switch it and generate again (chapter 6).
• A11 (air quality) generated no ticket. It is a room activity (“Applies to” = ambientes): it stays in the plan and in the PDF, but does not generate per equipment — the measurement is done by a laboratory. If you want a six-monthly reminder, create an activity with an empty “Applies to” (chapter 6).
• I clicked Generate schedule twice. Did it duplicate? No. The second generation reuses the schedule and only adds what is missing; the result shows already existed (chapter 7).
• I added a new split unit. How does it get in? Register the asset at the site, put it in a room (optional) and click Generate schedule: its pairs appear as new and the tickets are generated from today to the end of the horizon (chapter 7).
• I changed the validity and the schedule keeps the old horizon. The horizon is set on the first generation and does not follow the validity. Adjust the dates on the schedule page (Automatic Scheduling manual, chapter 6) or archive and create a new PMOC for the new validity (chapter 7).
• I activated the 2027 PMOC and the 2026 tickets disappeared? No: the 2026 PMOC was archived and its schedule closed (end = today, Finished). The tickets already generated stay on the agenda; cancel on the schedule page the ones that should no longer happen (chapter 7).
• The technician is empty on the Execution tab and in the PDF. H2O shows the technician of the ticket’s task, or the technician assigned to the ticket. Assign the technician (or set a default technician in the template) so that the name comes out (chapter 8).
• The ticket photos do not count as evidence. Only the photos of the task’s checklist items and the ticket attachments count. In the cleanings the template already asks for before and after; in the other activities, add an item with a required photo to the template (chapters 6 and 8).
• I want the PDF for September only. The screen generates the PDF of the whole period; the date range of the Execution tab applies only to the screen. The PDF address accepts the dates — ask support, or use the filtered Execution tab for the check (chapter 9).
• I deleted the PMOC and the tickets keep being generated. Deleting does not close the schedule. Close it on the schedule page (Planning › Automatic Scheduling) — or, next time, Archive before deleting (chapter 7).
