# Commissioning checklist

*Part 4 — Operate and fix.*

***

Work through this before handing an installation over. Most of it takes minutes; all of it is cheaper now than after the client has moved in.

***

## 29.1 The project

* [ ] Every unit in **Device manager** has a **Description** — not just an address
* [ ] Every address matches the physical hardware
* [ ] **No yellow dots** on any floor plan — check every floor
* [ ] Every wire in **Wire manager** has a **Name**
* [ ] **Project settings** carry your name and email as author
* [ ] The project **version** is set, ideally with **Increment version before save** on
* [ ] **Prefernces** shows nothing close to a limit
* [ ] The `.elp` is saved somewhere it will be backed up
* [ ] If custom function blocks are used, the `funcBloks` templates are exported as `.fncb` **or** **Save function blocks templates to project file** is on

## 29.2 The central unit

* [ ] **IP address**, **Mask** and **Gateway** are correct — and **written down**
* [ ] **DNS1** / **DNS2** set if the CU needs internet
* [ ] **NTP server** set and **Time zone** correct
* [ ] **CU time** matches **IDM time**
* [ ] **Error code** is clear
* [ ] Firmware is at or above the recommended minimum for every unit
* [ ] Cloud, MQTT or Modbus configured and tested, if used
* [ ] Passwords set — and recorded where the client can retrieve them

**Time zone deserves a second look.** It silently shifts every schedule in the building by an hour, and nobody notices until the seasons change.

## 29.3 Function testing

Test physically, not by reading the project.

* [ ] Every light switches from every button that should control it
* [ ] Dimmers reach full and zero, and hold at intermediate levels
* [ ] Hold-to-dim stops on release — no light creeping to 100 %
* [ ] Blinds run fully up and down, and stop when commanded
* [ ] Blind tilt is a tilt, not a full run
* [ ] Every group responds — and contains everything it should
* [ ] "All off" leaves nothing on. **Walk the building and look.**
* [ ] Scenes set the levels intended
* [ ] Each heating area's **Actual** and **Required** temperatures look sane in **Monitor**
* [ ] Heating actually fires — valve and boiler demand both
* [ ] **Antifreeze temperature** set on every heating area
* [ ] Time programs fire at the right times
* [ ] Sunrise/sunset switching happens at roughly the right moment
* [ ] Timers expire after the expected interval
* [ ] SMS and calls arrive on a real phone

## 29.4 The awkward cases

The ones that come back as callbacks:

* [ ] Power-cycle the central unit. **Does everything return to a sensible state?**
* [ ] Non-volatile system bits survived that reboot
* [ ] Two people pressing different buttons at once behaves sensibly
* [ ] A held button that is never released does not leave a light climbing forever
* [ ] Conditions that gate on time-of-day work **outside** the hours you tested in
* [ ] Heating does not fight cooling
* [ ] What happens if a temperature sensor fails?

## 29.5 Handover

* [ ] The client knows what every button does
* [ ] Written down, per room, and left with them
* [ ] They know how to change heating temperatures themselves
* [ ] They know who to call
* [ ] A copy of the `.elp` is stored somewhere they can get it
* [ ] Your author details are in the project
* [ ] The final project is uploaded and *"Projects are the same."* confirms it

***

## 29.6 The last check

Connect and confirm:

> *"Projects are the same."*

If it says *"Projects are NOT the same!"*, the central unit is running something other than the file you are about to file away as the record of this installation. Resolve it before you leave.
